  • DrFragle and MrShark Bakeey i5S Smart Mobile Watch by DrFragle and MrShark: i already can't tolerate the knob of a chronograf as it causes pain in my back hand when i bend my wrist, sure that will be way worse... it has to be seen how much those apps are usable on such a tiny display... Dec 10, 20:03
  • DrFragle and MrShark Early Christmas by DrFragle and MrShark: i think those tips are the same of the usual 936 soldering station, i've a clone of that and i bought a spare full stick, too, as it's easier while you're soldering and need a different tip to just swap the stick (as the bit is HOT) than just wait for the bit to become colder to let you change it... i use a fine conical and a chisel or flat tip, the latter most of the time as it transmits more heat than the conical... full stick for just less than 3€ 🙂 https://it.aliexpress.com/item/936-Electric-Soldering-Solder-Iron-Station-5pin-Welding-Hot-Gun-50W-24V-Replacement-Repair-Tool-High/32816328131.html Dec 10, 20:00

  • Peter Scargill Big Timer by Peter Scargill: I have no idea what hass.io is so can't help - perhaps someone else can comment. Dec 10, 10:35
  • Big Timer by Torben R. Pedersen: Hi all, I would really like to big timer to my node-red setup. I do however have a hass.io installation running on a RPi where I have node-red activated as a plugin to hass.io. As far as I understand it, then it means I'm unable to use npm. Are there any alternative ways to install big timer? Dec 10, 09:20
  • Hantek 2-in-1 Scope + Meter by PuceBaboon: Extra Christmas bonus from Banggood, built-in precognition mode (AKA "WTF" - Waveform Theorizing Function). It'll show you what the waveform -will- look like when you eventually get around to putting batteries into the test unit (scroll down the ad to the photo just above the bold, "3-in-1" text). I'll take two! 🙂 Dec 10, 01:30
  • Peter Scargill Hantek 2-in-1 Scope + Meter by Peter Scargill: Indeed, thanks for that, blog amended accordingly. Dec 9, 22:57
  • Hantek 2-in-1 Scope + Meter by Squonk42: Hi Pete, Here is the scope on Hantek website: http://www.hantek.com/en/ProductDetail_13174.html Dec 9, 20:21
  • DrFragle and MrShark More from Sonoff by DrFragle and MrShark: well, as they're very "basic" in any sense (you can't do much more that enabling the relay via the button, or detach the 2 behaviours and do whatever you want), and tasmota just works well (once updated to support this model) and has whatever we need to use them fully, ota included, who cares... once they work, leave them there and forget about them, just use them... but many prefer the Shelly these days, as they've native mqtt support on stock firmware... Dec 9, 20:00
  • Peter Scargill More from Sonoff by Peter Scargill: Sadly still with 1MB Flash - and no more GPIOI4 - GPIO2 available - but not brought out so you have to solder. At first sight I don't like it. Dec 9, 19:42
  • DrFragle and MrShark More from Sonoff by DrFragle and MrShark: it seems way better at separating high and low voltages and there's a fuse now, too, but gpio14 is gone, you have gpio2 on pad IO2 on back (no pins, beware to not overheat it when soldering a jumper)... Dec 9, 18:51
  • DrFragle and MrShark More from Sonoff by DrFragle and MrShark: beware, there's a new updated version of the sonoff basic, which has now 2 thick wires for mains, instead of pcb traces... more info on tasmota wiki: https://github.com/arendst/Sonoff-Tasmota/wiki/Sonoff-Basic Dec 9, 18:49
  • Bob A Thermostat Weekend by Bob: Hi Pete, Just spent the day incorporating this into my HA system. Super easy and works lovely. Many many thanks for sharing all the hard work you have put in on it. Dec 9, 15:39
  • Peter Scargill Acrylic RPI Case + Twin Fans by Peter Scargill: I just moved my main PI3 home controller complete with tonight's updates and 128x32 OLED into the new case. It's lovely. A set of rubber feet will completely eliminate any fan noise without having to reduce voltage. Dec 9, 01:30
  • DrFragle and MrShark Acrylic RPI Case + Twin Fans by DrFragle and MrShark: I had to bend the oled pins a bit to avoid touching underlying components, and put a bit of insulating sponge to push display towards the upper acrylic and let it stay fixed... The acrylic case inner layers are enough to keep it in the right position Dec 8, 23:25
  • Peter Scargill Acrylic RPI Case + Twin Fans by Peter Scargill: You're right, the 32 px OLED DOES seem to fit in which case it is going in. I already have Python drivers in there so Node-Red etc can run the display. Magic. Dec 8, 22:37
  • DrFragle and MrShark Acrylic RPI Case + Twin Fans by DrFragle and MrShark: I've similar case, single fan, though... You should remove the protective layer on the acrylic, they're transparent 😉 I put an oled display in the case itself, too, fits perfectly as you can see Dec 8, 20:35
  • Peter Scargill Digital Breath Alcohol Tester by Peter Scargill: Probably very large v- actually by the time I was done it was probably nearer to a bottle than a couple of glasses - and being at home I had no requirement to ponder any legal limits - as for the device - probably not VERY accurate - it's a fun gadget, not a scientific instrument. Dec 7, 12:17
  • Digital Breath Alcohol Tester by George: Are you sure it is accurate in any way shape or form? When measured in mg/100ml (also known as Promile or ‰BAC) – popularly used by the Police in the USA - current UK drink drive limit would be displayed as 0.80 or 080. So you were 2.5 times over the limit. Just how large were those bottles sorry glasses? Dec 7, 11:19

  • Node-RED Global Flow and Context by Latchiya Karthikeyan: Hi sir, I would like to assign statuses of 45 variables to false and then use them later in the program..I would like to know if we can set global variables in an array Dec 4, 06:43
  • Big Timer by Adam Kotniewicz: Hello Peter, Huge thanks for bigtimer. I am having a similar issue to "Sydknee". The only way i can get it to "override" is to set it to manual and then sent a "1" but then the override is permanent. NodeRed v0.19.5 Raspberry PI Zero on latest Stretch Dec 3, 23:45
  • Darren W Solar Motion Sensor Light by Darren W: My one of these is in use on the Norfolk coast, 5 mins walk from the beach, facing north rather than south so doesn't get the best of sunlight or weather in general really and has endured sub zero temperatures already. It's been there, outside in the elements most of this year and is still working great and that's more than I can say for some cheap Chinese tech that I have bought that's never left my centrally heated man cave! Dec 3, 23:04
  • Big Timer by Sydknee: I got to the bottom of the problem with a bit of fiddling . The timer was set to a specific day of the week and won’t override unless it’s on that day. Either this is by design or a bug but as I only want to override on that day it works out ok for me. Dec 3, 22:38
  • Peter Scargill Big Timer by Peter Scargill: Whether you need a topic depends on. What you are feeding. For input values see the readme. 1 and 0 are good are on, off and auto. Dec 3, 22:16
  • Big Timer by Sydknee: I'm having a bit of an problem with inputs on the big timer, whatever I try they don't seem to work. I might be missing something obvious but from reading above I just need to inject a 1 or 0 (simplest form). I've tried also on and off also on_override but nothing happens. Does it need a topic? Pretty new to Node-Red but liking the other functions of Big Timer. Dec 3, 20:30

  • Peter Scargill H96 Max Plus USB 3 TV Box by Peter Scargill: As the unit is supplied with Android and intended specifically for use as a TV box I can't be of much help if someone chooses to hack it and use it for something entirely different. The only thing I would (and did) change on this unit is the remote. Dec 3, 12:17
  • H96 Max Plus USB 3 TV Box by wdt: I have one of these, specifically rk3228-8d4-v1.1,, it has a problem running any linux.. Uboot sees uSD OK, kernel loads, the dtb, then loses uSD, if you have a usb stick with right LABEL or uuid it will run from that After quite a while I have hacked a blodge, many errors in dmesg, runs from uSD, I still don't understand the problem (which is in dtb).

  • Village idiot LCD Display for Node-Red by Village idiot: > In /home/mat/.node-red/settings.js, I've added httpRoot: '/red'. This changes the urls for admin and dashboard to /red and /red/ui Mine works and I don't have that set. You may need to set up: httpStatic: '/home/mat/.node-red/public', Just below what you did. and put the fonts in the public directory. That may help. Dec 1, 07:40
  • Village idiot LCD Display for Node-Red by Village idiot: When I posted that, it was true at that time. To put things in context - as that seems to have been lost in the post. As I don't understand what is written - and that is nothing against who ever wrote the instructions - *I* had to put in the extra effort to understand what was written. That I can understand it doesn't mean anyone else who reads what I did any easier. So: me putting in the hard yard is that I had to read what was written and translate it to something I can understand. As to "help": Yeah, well I am trying, but it isn't easy and the lessons are on-going and of little benefit. But I guess it is slightly mitigating the net effect of doing nothing. Dec 1, 07:36
  • LCD Display for Node-Red by Mat: Nobody is going to punish you. But I think you may need some emotional support or help, based on the things you said. I say that with all sincerity. As for the content of what you said previously: "I am looking up and down in the replies and there is a very poor explination of what to do." [sic] " ... it would have helped the other person (Neil East) and myself a lot of pain had there been clearer stuff saying what to do." "eg: This is where you get the fonts ....... Set up of "myfonts" in the settings.js file ....... Copy these to "myfonts" ......... Done. But that's just a thought." It's very odd that you seem frustrated nobody spelled it out for you, then later you say "I have to put in the "hard yard" to get answers", implying that you are choosing to deny others the same that you hoped for in the first place. As for suggesting I "expected you to post the answer" and that I "want you to be nice to me" - neither of these things have I said to you. Anyway, good luck! Nov 30, 23:54
  • Village idiot LCD Display for Node-Red by Village idiot: Hi Matt. Yeah, you are right. But all I can say in response is: We are all brought into the world pretty much equal. No biases, etc. As we go through the journey of life, we are changed by how people treat us. Sometimes good sometimes bad. You are expecting me to post the "answer" to the question after I worked it out. Which is fair enough in some respects. But understand that I am mirroring how people treat me. I have to put in the "hard yard" to get answers. Which is also fair enough. This entire layout/syntax/system is BEYOND ME! I'm an 80's computer person. I NEVER was taught the languages/syntax/etc. It is still mostly "conceptual" to me. The fact I can get things done is still **more luck than skill.** So: If you want me to be nice to "you" how about you set a good example for me to learn from? (And I'lll let that syntactical error pass: ending with the word "from") If that is how you are going to talk to me, why would you expect me to talk any better to you? There are MANY DECADES of me being treated like crap for me to get over. When this happens it only takes away all the work I have done to become better. I'll shut up now. I really don't need this. And I am probably going to be punished for being "a smart arse" and the reply is "not welcome". Nov 30, 22:47
  • Julian Knight RFLink and Node-Red by Julian Knight: None of this existed when I started my journey into Home Automation but I invested early on in a RFXtrx433E USB device that Max Hadley very kindly created Node-RED nodes for. That unit has been live for years now and works flawlessly. Connected to my Pi. Node-RED is used to listen for inputs from many devices including various doorbells (currently 1byone), HomeEasy PIR and magnetic door sensors and an Oregon Scientific temperature/humidity sensor. Outputs go to the doorbell ringers, Lightwave, HomeEasy and other switches. 433MHz was the only cheap game in town when I started so the £80 or so investment in the RFX unit was easily repaid several times over. Now, of course, with cheap ESP's, things have changed a lot though 433MHz is still great for really low-power units. Incidentally, the RFX has no problem with signal reach right through our 5 bed Victorian end-terrace. Though it does require a little care in placement as it is in the loft. What is weird is that a year or so ago, after a rare firmware upgrade (the unit gets regular updates published, I just rarely update it). It suddenly started receiving far more signals from houses around us 🙂 Nov 30, 17:54
  • Peter Scargill Solar Motion Sensor Light by Peter Scargill: My panel (the subject of this blog entry) is currently in the Northeast of England.. let's see how it handles the winter. Most fail the test. Nov 30, 17:47
  • Julian Knight RFLink and Node-Red by Julian Knight: That might explain why I settled on using them for everything. I'd had loads of power problems with other ESP units before I hit upon the mini. I'm not very good with electronics so I could never sort things out previously. Nov 30, 17:44
  • Julian Knight Solar Motion Sensor Light by Julian Knight: Love the idea of shoving an ESP inside. Good call. Not so sure about these though, here in the North of England. I note that some similar units have people complaining about them not getting enough charge and this will be significantly compounded in the winter when you have bad weather, short days and the cold to deal with. These cheap units all seem to have some form of LiON battery and these not only don't charge well below 0 deg. they also have greatly reduced max. charge when operating below zero. Nov 30, 17:36
  • Julian Knight Credit Where Due–MQTT Logger by Julian Knight: It doesn't trigger Windows Defender. But it does mark it as untrusted since it isn't a signed executable. Nov 30, 17:05
  • Julian Knight Credit Where Due–MQTT Logger by Julian Knight: Well, it certainly has some uses I can see. It is only a 32bit app which isn't ideal and isn't signed which makes Windows 10 nervous understandably. It also tried to automatically create a link, I'm guessing on the desktop which fell foul of my advanced security settings 😉 But it works and I like the grouping and filtering. Not really all that useful if you have JSON payloads though. Also, I think you can only connect to a single MQTT broker? I use 2 at the moment. Still, more useful than the busy MQTT-spy UI if you just want a quick overview of a single broker. Connected to my live HA system, it is currently using 126MB after 5 or 10 minutes and very little CPU. Seems to peak and then return to around 110-113MB. Naturally, this is creeping up as it logs more data. Nov 30, 17:03
  • LCD Display for Node-Red by Mat: Argh, spent about an hour now screwing around trying to get fonts to work. I have read every single comment on this thread and followed various links to other blog posts to no avail. Here's what I've done: Default install of node red. In /home/mat/.node-red/settings.js, I've added httpRoot: '/red'. This changes the urls for admin and dashboard to /red and /red/ui Then in the same file I set httpStatic: 'public' and create the directory /home/mat/.node-red/public. I add a text file to test, called hi.txt, restart node-red and try to access it from //blah:1880/hi.txt - in the browser it says "Cannot GET /hi.txt" What am I doing wrong?! Nov 30, 11:54
  • LCD Display for Node-Red by Mat: You made a long whinge about how there are no clear instructions anywhere, spread over 3 or 4 posts. You even set out a template for how information should be presented, to be more helpful to other people. Then you figure out the answer and surprise surprise, absolutely no help to others in your comment, who might be struggling with the same questions you had. Good work! Nov 30, 07:57
  • Peter Scargill The Script by Peter Scargill: Good. Time to investigate further then When I get back off holiday and into the UK and in front of a PI, perhaps Antonio and I will do a little experimenting. Thank you for that. Nov 29, 15:04
  • DrFragle and MrShark The Script by DrFragle and MrShark: as i already said here, now the email node REQUIRES nodejs8, which has caused MANY issues to A LOT of us, npm/bcrypt/hw related... so we're sticking to v6, for now... i hope v8 issues are addressed soon (even docker nodered container guys suggest to use v6 for now...) https://tech.scargill.net/the-script/#comment-45725 Nov 29, 13:24
  • Jbreda01@gmail.com The Script by Jbreda01@gmail.com: also, i sent this along to the node guys and they think its a problem in the script also: Just a quick question, the node-red-node-email node gets installed during the node-red installation as a default. There is a newer version available as the palette manager says there is an update, but it is not updatable from the palette manager as it is installed globally. It has to be uninstalled and reinstalled to work. Little bit of a pain. Nov 29, 10:34
  • Jbreda01@gmail.com The Script by Jbreda01@gmail.com: Ok Pete, Did as you suggested and ended up with the following solution to the above problems: When node-red and npm are installed by the script, the errors occur. I'm not exactly sure why but it does. If I wipe my pi and reinstall stretch, then system updates, then npm, then node-red, then run the script omitting the npm and node-red install options, everything works perfectly. Solved Chris's problem also. Great script and thank you for your help. John Nov 29, 10:11

  • Peter Scargill The Script by Peter Scargill: Pretty much how I do it but once I got a working setup a while ago I started cloning from rpi-clone backups so I can't comment on new bcrypt issues. Nov 27, 23:34
  • The Script by Chris Dobson: Instead of changing bcryptjs from root to pi, i left its owner as root but changed permisions then tried to install from command line: pi@NodeRed2:~/.node-red/node_modules $ sudo chmod 777 bcryptjs pi@NodeRed2:~/.node-red/node_modules $ cd $HOME/.node-red pi@NodeRed2:~/.node-red $ npm install node-red-contrib-combine + node-red-contrib-combine@1.6.2 added 1 package from 1 contributor, removed 1326 packages and audited 1 package in 57.309s found 0 vulnerabilities REMOVED 1326 Packages!! BROKEN Again. I just don't get why it removes all the other packages. Would it be possable to install new nodes into a different folder so they dont delete all the other stuff, like in the httpstatic path? Nov 27, 22:13
  • The Script by Chris Dobson: My Walk through of node red install with the script.(Headless). 1. Wipe and format sd card. Ease partition master seems to work better than SD Formatter. 2. Write raspbian image to card. Win32Disk Imager still works for me. 3. Before putting card in raspberry open it up in windows explorer, and in the root directory make a new blank text document and save it as ‘ssh’ (without quotes). This will enable SSH on boot. No need for Keyboard & Monitor !!! 4. Put card in Pi, connect wired network and power. Wait for it to boot. 5. Check router to see what IP address is. 6. SSH into it (I use Putty) Logon = pi, password = raspberry. 7. Check file system (you used to have to expand it to use all the card, but recently seems to be already expanded. df –h 8. sudo raspi-config and enable ssh, I2c and serial and disable serial console - others may have different requirements. 9. sudo nano /etc/ssh/sshd_config and Change #PermitRootLogin prohibit-password to PermitRootLogin yes (uncomment!) save and exit. 10. Restart sshd service using: /etc/init.d/ssh restart or sudo reboot 11. Set a root password if there isn't one already: sudo passwd root 12. Now you can Log in as root. 13. Get the script wget --no-check-certificatehttps://bitbucket.org/api/2.0/snippets/scargill/ekon6o/master/files/script.sh 14. And then bash script.sh 15. Script will start, and after a few seconds will ask you to log out as root and log in as pi, then bash script.sh Again. 16. It will ask you to change user password, admin password then Pi password and root password. 17. Then you get the options menu, select what you want then GO!.........wait . (pi3 Model B with all options about 35 -40 mins). This method has always worked for me, but now i can't load new nodes via pallet, got somthing to do with permissions of bcryptjs being root.

  • The Script by Chris Dobson: Have you tried with rasp jessie ? i have that on my main controller with node red v0.17. 7 and it has been running for over a year,maybe two, with no problems.

  • Jbreda01@gmail.com The Script by Jbreda01@gmail.com: Thanks peter, yes. I have installed a new copy of stretch on the pi, updated the system and ran the script - once as root as mentioned in the script which takes me in to the user pi than run the script again as pi. Also tried just running it again on a fresh system from the pi user and get same results. All goes well until I try and install the node-red-contrib-simple-gate node (which always fails) with the above messages. I am now reinstalling everything fresh again and will try the node install and report what happens. Actually, I have spent too much time on this and I cheated. I put the problem node installations in the script and ran it again and they installed ok. Node-red-node-email is a problem as it gets installed globally and cannot be updated from the palette, so needs to un-installed and reinstalled again. Have done this successfully before but with the new install I now get the following when I try and reinstall email node: npm i node-red-node-email npm WARN deprecated mimelib@0.3.1: This project is unmaintained npm WARN checkPermissions Missing write access to /home/pi/.node-red/node_modules/bcryptjs npm ERR! path /home/pi/.node-red/node_modules/bcryptjs npm ERR! code EACCES npm ERR! errno -13 npm ERR! syscall access npm ERR!

  • The Script by Chris Dobson: I'm having similar problem. Pi3 model B. after running script all seem ok, until you try to install extra nodes. after looking at the log file it is a permission problem with file /home/pi/.node-red/node_modules/bcrypt. when you look at it in winSCP you can see that its owner is 'root', (all other stuff in there is 'pi'. So using putty as user 'pi' as i cant get into root (access denied) i did a sudo chown on that file to pi. i then went back to node red and tried installing again. it worked!! i installed another brilliant!! feeling very pleased with myself i went off to bed. Came back to it this evening and all seemed ok, Until i rebooted. node red no longer starts! I thought no problem i will just change the permissions back to root, reboot and try something else. But All the files and folders have gone !! all that is in node_modules is the two nodes i added. P.S. when i run the script it says must be run as root the only way i can get to user root is sudo su. could this be relavent? Anyone Help ??? many thanks Chris. Nov 26, 22:23

  • Blade2021 Big Timer by Blade2021: Hi Peter, First and foremost, absolute big fan of your big timer node. I've been using it since I started building upon my smart home and am actually astonished that you keep up with it and all the other projects you are conquering. I do have a question though. I am using the bigtimer node to as a regular timer in one part of my home, I send a timer 45 input to set the timer to turn off after 45 seconds. Is there a way to cancel this action after its sent? Thanks, - M Nov 25, 03:12
  • Bob Green The Script by Bob Green: Hi Nicolass, I had the same problem running 'the script' on a dual boot PC using ubuntu 16.04. I found some information on the net about the npm issue, unfortunately I didn't make a note of the source. Basically I installed npm manually and then selectively ran just the part of the script to load the node-RED nodes. Well that's as much as I recall. Once done all the other stuff 'the script' installs runs beautifully. Dr Fraggle and Mr Shark is the real expert on the Linux stuff and he may be able to provide far assistance than I can.

  • Bob Green Credit Where Due–MQTT Logger by Bob Green: Hi Phil, I had exactly the same situation with Kaspersky anti virus, It detected supposedly malicious code in the .exe file. Probably a false positive but it made me wonder what anti virus software people were running who got the software to work properly. I haven't had time to try it again, perhaps by somehow telling the AV the software is OK. Kaspersky deleted it from my system. Kaspersky which I use on six machines has never been any trouble for years. I do not know if it is possible to send the software to Kaspersky and get them to check it. I also left a note on the authors GitHub but to date have received no response. Nov 24, 23:41
  • Credit Where Due–MQTT Logger by Phil Grant: Well I tried to install it but Avira anti virus blocked it with "Heur/APC" found. Possibly a false positive, anyone else had this? Nov 24, 20:57
  • The Script by Nicolass: The work here is awesome. Thank you so very much. It looks like the script will not install under an amd64/x86 distro of linux. I have tried ubuntu 16.04 (I have two machines running it now on ubuntu 16.04), mint linux, raspberry pi desktop, and a couple other debian variants. The issue I have is the npm does not get installed -- claims missing dependencies. The script works fine on rpi with noobs/rasbian. Any advice? Thank you again Nov 24, 20:49

  • Bob Green Sonoff T1 by Bob Green: Dave, one of the things I like about Peter's blog is the sharing of information. I wasn't aware of the switch spacers. Another way to get 2 or 3 mm would be to fit those finger plates designed for light switches, intended mainly to keep the wall clean around light switches. Nov 22, 09:11
  • New Toys in the USA by Mike: Interestingly, I found when living in the USA that the vast majority of common out-of-patent (generic) drugs were very inexpensive, especially at WalMart who offered a great pharmaceutical service. Now I'm back in Australia, don't even start me on limited ranges and grossly inflated prices for electronics! Probably far worse than the UK! However, we do have an excellent medical system - a mix of private and public that is, I'm informed, similar to that in Canada. Yes, there are waiting lists for public, but no-one goes without because they can't afford it - a la USA. Nov 22, 08:27

  • Scott Millken New Toys in the USA by Scott Millken: "Such a shame that with an obviously thriving consumer market here in the states, there is also a completely corrupt pharmaceutical industry. We just got charged more for a month’s worth of widely-available blood thinners than I paid for my last mobile phone." As one that resides north of the 49th, (USA) it amazes us as well at the very poor medical and pharmaceutical systems they have in place or not in place. Have to love the cereals tho! Hope you have a great holiday! Nov 22, 02:09
  • Sonoff T1 by dave: Thanks for the quick reply Bob. My living room back boxes are 25mm but my cables (live, switched live, neutral and earth) are all run inside conduit so any excess cable can be pushed up inside the conduit and out of the back box area, so I might just get away with them. Our bedroom back boxes are a different matter though (only 16mm deep), so I will need to make them deeper at some point, in meantime I could always add some of these 10mm spacers (there are places on ebay selling 7mm thick versions and 20mm thick versions). They will probably spoil the look of the switch but as a temporary solution or until sonoff come up with a much thinner/more compact design, they will do the job. https://www.screwfix.com/p/schneider-electric-lisse-1-gang-spacer-white/5782j Cheers Nov 21, 16:55
  • Bob Green Sonoff T1 by Bob Green: Dave, I can't give you the dimension from the rear of the fascia plate to the back of the Sonoff but I doubt it would fit in a standard 25 mm back box and leave any room for the wires. I think you would need a 35 mm back box to get the unit in without trapping / crushing the wires and to be safe. Nov 21, 14:22
  • Sonoff T1 by dave: How deep does the wall back box need to be for a Sonoff T1 (UK version) ? The sonoff website says the overall depth of a Sonoff T1 (UK version) is 32mm, but what looks between 5-10mm protrudes from the wall, meaning actually depth required is really somewhere between 22-27mm. Can someone give me and exact figure? Thanks in advance. Nov 20, 19:18
