  • Peter Scargill USB Soldering Iron TS100 by Peter Scargill: thinking about that, the supply is able to deliver at least 1 amp at 12v Apr 20, 14:40
  • FeelTech FY6600 Waveform Generator by BSense: Hi Peter. This is a silent follower (that teaches NodeRed and has made some custom nodes ;). Anyway I am glad you are recovering. I just wanted to ask you (or maybe warn you) about the firmware issues of your FY6600. Which firmware version is it flashed in your unit? It seems that release 3.0 (and to lesser extend 3.1) tends to self destruct by flash overwriting. Regards. Apr 20, 14:25
  • Peter Scargill USB Soldering Iron TS100 by Peter Scargill: That is a very good point, though it still does not explain difficulty in finding the official software... but I will amend the blo based on this feedback, thanks. Apr 20, 14:23
  • QuickFix USB Soldering Iron TS100 by QuickFix: Please remember that it's a 65W iron: if your PSU isn't beefy enough (eg. 1A@12V) it doesn't work at all (not even a bit); you'll need at least a power supply of 6A or more when using 12V. Greetz, Peter (I've just registered an account) Apr 20, 12:59
  • Peter Scargill USB Soldering Iron TS100 by Peter Scargill: I can see on that site a link to 3rd party software, but not having luck finding the official update. However as the iron should already have software on it and I can't get it to heat up with 12v on the second input, the point is somewhat mute. Thanks for the info. Apr 20, 12:51
  • USB Soldering Iron TS100 by Peter: The official firmware can be found on the forum of miniware.com.cn (mind the .cn TLD): http://www.minidso.com/forum.php?mod=forumdisplay&fid=67 The iron should be seen as an external drive when plugged into a free USB-port, if it isn't try another port or even another PC. If that still doesn't work, there's great chance you've got a defective iron (as it also should already contain working firmware and work right out of the box). Apr 20, 12:29
  • Peter Scargill USB Soldering Iron TS100 by Peter Scargill: I wish mine would heat up... the only other iron I have here is WAY too big for smd work Apr 20, 08:45
  • Emil Chobanov USB Soldering Iron TS100 by Emil Chobanov: I use this soldering iron for more than 2 years. This is very useful. I supply with 18V old Compaq adapter. I like mostly quick time to start, for me there is no such time :). And I am happy with auto switch off function too. May be negative is too light and hard to find the appropriate power connector at the adapter side. I use TS-I solder tip perfect for SMD and TS-B2 for other cases. The solder tips can be changed very quickly. May be use of 2 TS100 will be more convenient, but the price is no so low for that. Apr 20, 08:42
  • Peter Scargill Sonoff 4CH PRO R2 by Peter Scargill: I never did figure out their naming scheme.. Non-pro I guess is equivalent to "amateur"... don't know why they didn’t just call it version 2.. anyway, a nice boxed unit at a reasonable price. Apr 20, 07:50
  • Sonoff 4CH PRO R2 by Steve Lenehan: Maclej - As does the R1 version - maybe you are mistaking it with the non Pro version Apr 20, 07:20
  • Peter Scargill The Script and ESP8266 Code for Beginners by Peter Scargill: esp8266flasher.exe appears to work well, I've been using that myself. Only wire GPIO to ground for programming.. ie before powering on or with reset.. with GPIO to grounde under those conditions it should program up, it should be high any time. GPIO12 is a good choice for testing with a LED. When programming there is an additional complication that some WEMOS D1 boards need DIO mode, mostly, other boards need QIO mode, this can be set in ESP8266flasher.exe before you start programming. Apr 20, 06:52
  • Peter Scargill Sonoff 4CH PRO R2 by Peter Scargill: Yes I can see that being useful. Apr 20, 06:45
  • Sonoff 4CH PRO R2 by Maciej: The most significant difference is that it works with 5-24V DC input. This is big! Apr 20, 05:22
  • Randy The Script and ESP8266 Code for Beginners by Randy: Pete, hope you are recovering well. I found your site about two weeks ago from a video that Andreas Spiess had posted about your script and use of the ESP8266. I have read most of the posts regarding the script and flashing the ESP8266. Great information. Thank your for your work and sharing it with the community. I am pretty much a novice to the electronics work. I have several ESP8266s and have tried flashing your code to a couple of them. If I can throw in a little humor, I don't have an uncle named Bob (or the many years of experience in electronics you have) so I am having some issues with the flashing of your code. I have downloaded the ESP8266Flasher.exe program and used that to flash the three files to the chip at the addresses specified. That appears to work ok. I see LED activity and the progress bar shows the activity. After this is complete I unplug the USB and plug it back in. I have used both the Serial Monitor from the Arduino IDE and Putty to look for serial activity and don't see any. I have tried wiring the GPIO0 pin to ground, and GPIO to a LED. Any help/thoughts would be appreciated from anyone. Thanks Apr 20, 05:08

  • USB Soldering Iron TS100 by leo: It did work well a couple of months ago, will try later tonight, the firmware is waaaay superior than the original one, it's a must. Also, you can play tetris on it! looking through releases looks like there is a new version of the hardware? https://github.com/Ralim/ts100/releases Apr 19, 12:53
  • Peter Scargill The Nano Peripheral Update by Peter Scargill: I use the Aliexpress 5v 328 version, sometimes with ftdi built in, sometimes not. Apr 19, 11:55
  • The Nano Peripheral Update by Dan Barnett: You might like to look at the Pro Mini module from AliExpress. There are versions with and without the FTDI and also versions with the 168 or 328 chip and also 3.3V or 5V. This one is $1.88: https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwiv8vPkocbaAhUIuMAKHRzpCZoYABAUGgJpbQ&ohost=www.google.com&cid=CAESEeD2IYl6ONl-5DYKA5-zT9CD&sig=AOD64_3xpsLcHshi2UPH39cfwwEMcnN36g&ctype=5&q=&ved=0ahUKEwjC5u3kocbaAhUK84MKHfyVDiQQ9aACCEI&adurl= Apr 19, 11:52
  • Peter Scargill Sonoff 4CH PRO R2 by Peter Scargill: I can confirm the board IS DIN rail mountable so that's wrong Apr 19, 09:46
  • Steve Lenehan Sonoff 4CH PRO R2 by Steve Lenehan: Looking at Itead website it appears the only significant difference between this unit and the original version is the change to the range of time delay options in inching mode which seems odd given the nearly 25% uplift in price. The Itead site also implies that the new model is no longer DIN rail mountable. Can you confirm? Apr 19, 08:47
  • Peter Scargill USB Soldering Iron TS100 by Peter Scargill: You've both had more luck than I. Apr 19, 08:01

  • USB Soldering Iron TS100 by Vlastik: Hello Peter, I highly recommend trying this firmware: https://github.com/Ralim/ts100 - it contains lots of new features and is actively developed. I like adding my own starting logo, changing the temperature on the go and boost mode. Apr 19, 05:52
  • Mustool G600 Microscope from Banggood by Phil Grant: OMG!! I bought a 20Meg MFM hard drive from a Radio Rally once only to find it had no heads inside! Apr 18, 21:27
  • Steve Lenehan The Script and ESP8266 Code for Beginners by Steve Lenehan: For what its worth I used a combination of standard TRV bodies with a 220V thermal manifold https://www.aliexpress.com/item/230v-24v-normally-open-close-Electric-thermal-actuator-for-manifold-underfloor-heating-valve-radiante-actuador-M30X1/32842183873.html?spm=a2g0s.13010208.99999999.262.TpZhb0 connected to a Sonoff Basic or Sonoff TH and for those where mains power was not convenient I used battery powered bluetooth TRV's. As all the radiators have standard TRV valves and its usually cheaper to buy complete TRV sets than just valves alone they can be installed and tested as standard TRV's. Replacement is then a simple screw off screw on task. As for sensors you can use any combination talking to your control point but I would suggest the Xiamo Zigbee gateway and temperature sensors for the price you get a system that is cheaper than a "build your own", good range and extensible with other sensors - all of which can then feed into Node Red for controlling the valves. As to NO/NC it is just a matter o how you would like the valves default - I make sure mine open and close on a weekly basis to prevent sticking . Partial opening is not practical unless you cycle them rapidly which would not be good for the device and given the delay in room temperature reflecting radiator position probably not practical Apr 18, 14:39
  • Tom Strickland The Script and ESP8266 Code for Beginners by Tom Strickland: Thanks for the reply. I should have said that I do intend to use BME280s. Is it possible to use Nano(s) to allow several BME280s per esp8266? Apr 18, 13:07
  • Peter Scargill The Script and ESP8266 Code for Beginners by Peter Scargill: Personally I'd be powering the valves with 220v (UK) though the alternative would be a low voltage supply for each valve, you really don't want wires all over the place. Partially open? Well I guess that depends on what kind of valve. The alternative is manual valves (standard radiator) - definitely not per-radiator thermostatics - and zone by room or floor. I use an esp8266 in the area of zoning, I would have used a Dallas DS1802b in the past or a DHT22 (heaven forbid, don;t use a DHT11) - but today as my ESP8266 handles I2C, I plan to use BME280 boards. My Pi Node-Red software talks to the ESP8266 boards with manual override where needed. Apr 18, 11:16
  • Tom Strickland The Script and ESP8266 Code for Beginners by Tom Strickland: It is so good to see you making such progress in your recovery. I have had friends go through similar and strong early progress such as this is probably very heartening for you. I am having our house's central heating partially replaced and would really like to make the whole setup more efficient. I plan to use the excellent-looking Home Control script. I have a few questions about how to plan this. The problem is that we are having the plumbers in quite shortly and I need to have the valves in on the radiators, and some control of the boilers, but it's all happening quite soon, before I can be certain of having a complete Home Control setup, so I am looking for a way to have some intermediate steps that will allow me to get past the plumber stage. Eventually, I am looking forward to adding weather control, and extractor fans in various parts of the house that switch on & off depending on outside humidity. I am excited by the possibilities beyond that, but the ability to get on top of our heating & damp issues is most exciting. This project is exactly what I am after. This is a large Victorian house. Sometimes we're only interested in heating one room, sometimes the whole house. Gas boiler, supplying water to radiators on 3 floors. The plan: - 3 CH circuits, one per floor - remote control valve on each radiator - Bosch BME280 sensors throughout house to enable precise monitoring of temp/humidity - The eventual aim is to have easy control of the CH system on a timer, with it being easy to override on a per-room basis, but considering that the house is basically running as two zones at the moment, I am happy to take the shortest path to having a working CH system and have fine-control sorted out at a later date. I need to be able to get the valves installed such that the plumber is happy to sign off on them and work backwards from there. Plan of attack (feel free to critique): Milestone 1: all valves can be somehow set to a position that the plumbers will be able to test the system. Milestone 2: boiler circuits can be controlled on a timer Milestone 3: a radiator can be controlled. Milestone 4: control of all valves, and the boiler, on a central timer per circuit. If possible, the ability to set radiators to an intermediate position. Milestone 5: temperature sensors in each room, temperature targets in each room. Questions: 1. What valves should I use? 1a. Normally open or closed? 2. Can the valves be partially open? This would seem to be more intuitive to me, as heating could be steadily supplying enough heat to a room to keep it at the desired temperature without cycling the boiler excessively. 3. Does the plan of attack above sound sensible? 4. Power supply considerations. This is the one that has been paralysing me slightly. How do I get power out to all these controllers & sensors?

  • Peter Scargill The Script and ESP8266 Code for Beginners by Peter Scargill: Just took a look to remind myself. AnalogWrite (0-255) has nothing to do with analogRead (0-1023) and as my writing is deliberately slow for PWM, a readback function would sensibly have to read the INTENDED value not the actual value which limits its usefulness. Apr 17, 21:08
  • The Script and ESP8266 Code for Beginners by Leo van der Hoek: I want to read my PWM OUTPUT! Can I send command nano:9,5,10? Here is 10 an OUTPUT set by nano:9,12,10, According to your command definition I will get back a message in JSON format on MQTT. However what is the topic of this message so I can subscribe to it? Why I do this? Because I have some LED supplies with PWM level control. I however added a bit of logic to handle local control by touch switches to be able to set my LEDs also when MQTT is down or as an alternative operation mode without using the NodeRED dashboard. Now I only show the value sent to the LED, but I want to read the level from the output so I can see "local controlled" changes. Apr 17, 15:35

  • Peter Scargill Big Timer by Peter Scargill: Right, I'm taking a look at this. There are two types of override, temporary and permanent. It makes no sense to have a temporary override to a timer that is not on today, but perhaps the permanent override could run regardless. I'll need to ensure this does not create any conflicts, and if not, then I'll arrange so that if you preselect manual then select 1 or 0, there's an output regardless. That should keep everyone happy. Apr 15, 08:26
  • DrFragle and MrShark Mustool G600 Microscope from Banggood by DrFragle and MrShark: whatever you want, but to have your rights affirmed you need to ship back the good to china mainland, and in a trackable way... this usually costs more of the broken good, so better buy a new one...

  • Mustool G600 Microscope from Banggood by Phil Grant: I'm going to read the Ts&Cs I think just to understand what the warranty is, it doesn't look like it's the same as here. Of course there is no legal requirement in the UK for 12 months warranty, there is consumer protection law but this isn't the same.

  • Mustool G600 Microscope from Banggood by Phil Grant: I wonder if the warranty is different on different devices or it may be that you're a reviewer of their kit, I don't mean that in negative way just it's a fact to consider.

For alexa I used the home skills node and set up a device, this requires setting up an account.

  • The Nano Peripheral Update by Ed Darby: Ah good to know, I got the bare chip DIP versions and to be fair, due to a shipping error I got them for 9.9 pence each πŸ˜‰ I'm making a home controller for the wife who is, how can I put this delicately? a little technologically adverse πŸ˜‰ The idea is, there a 10 way selector switch, a push button and a rotary encoder. This sends MQTT messages via an ESP 12-E running espeasy firmware, to node red that toggles what she wants on and off, set the selector to, say, TV, press the button and the TV turns on, set it to lights, press the button et voila the lights come on. The rotary, I originally designed to change the volume to whatever the rotary value was but settled on turn it left and volume goes down by 10% and vice versa as she was happy with that. It's eventually all going to be mounted inside a vintage bakelite radio housing with some WS2812B's to give it a glow behind the old dial πŸ™‚ It looks an atrocious mess in it's prototype form atm but works like a charm!

I've been using 'TheScript' for a while now and it is very helpful. I just added SonWEB yesterday and I didn't have any trouble. If you are interested in adding it to TheScript, it is at https://github.com/reloxx13/SonWEB. Anyway, keep up the good work and stay away from the hospital. πŸ™‚ Apr 11, 19:57
  • Peter Scargill FeelTech FY6600 Waveform Generator by Peter Scargill: excellent. good news. A 6800 unit is on its way to me to test. Apr 9, 22:51
  • Andy Thomas FeelTech FY6600 Waveform Generator by Andy Thomas: Thanks for the quick response! Actually it seems you can do this - I've since downloaded the user manual and it seems the output from CH2 can be used to modulate CH1 and the Trig/FSK/ASK/PSK rear panel socket can accept external inputs as well. For the price and the fact I've not bought any test gear for years (last RF sig gen I used was a Marconi TF144H where I worked in the 1980's), I'll get one of these. Will let you know how I get on with it, Andy Apr 9, 21:48
  • Peter Scargill FeelTech FY6600 Waveform Generator by Peter Scargill: Who better to ask than the manufacturer? Apr 9, 20:01
  • Andy Thomas FeelTech FY6600 Waveform Generator by Andy Thomas: I'm thinking of buying one of these to use as a traditional RF signal generator when repairing or re-aligning vintage AM & FM radio sets. But what I can't find in the FY6600 spec is whether it's possible to generate a modulated RF carrier, modulated AM or FM with, say, a 1 KHz sine wave? Is this possible with this unit?

  • Peter Scargill The Script and ESP8266 Code for Beginners by Peter Scargill: Thank you Dennis. Glad the script works for you. Several people helped make this work reliably. Apr 9, 17:09
  • The Script and ESP8266 Code for Beginners by Dennis Bourassa: I've been using your great Script for over a year, without a hitch. Thank you !! I just received a new Raspberry Pi 3 Model B. I installed a hard drive as a boot drive, ran your Script, and watched as it installed without an issue. Net result, the Script screams on a Raspberry Pi 3 Model B running off a hard drive. I have 23 Tasmota MQTT devices on my network. I'm so glad your back and best wishes with your recovery. DennisB Apr 9, 16:25
  • Peter Scargill LCD Display for Node-Red by Peter Scargill: Very good. Apr 9, 15:32
  • LCD Display for Node-Red by marc: the WAF on this is super high. thank you! i especially love the 'old-timey' effect with the faded digits ... and its potential to burn our screens πŸ™‚ i've put this in a super large widget (22x14) -- the #back div changes image-background on a timer; then #inside (has the clock) and 2 animations to move it around. #inside { animation: screenSaveX 200s alternate infinite, screenSaveY 175s alternate infinite } @keyframes screenSaveY { 0% {top : 20px; }100% { top : 250px; }} @keyframes screenSaveX { 0% {left: 30px; }100% { left: 400px; }} Apr 9, 15:22
  • Sonoff TH10 and TH16 by Peter Diffey: Hi Darren I am in UK I have lots of Byron Homeeasy kit, which is 433Mhz I also have a Telldus USB stick connected to an old RPi model B. My first attempt at programatic control was with an Arduino conncted to a linuc PC (2012). ambituous but rubbish as they say - it worked but only as aconverastion piece. I have 12 sets of ceiling lights controlled via 433 actuators- these are all in my modern house extension, they are controlled by wall mounted 433 remote switches. all that works quite well. all these actuators can be controlled by up to 8 remotes, and they are self learning. In the old part of the house most of the lights have wired switches. Like your solution, it is user friendly, no wifi everything still works. The RPi runs telldusd and a web server, so by opening a port on my router I can control the lights from a phone. I have also installed postfix and procmail on the RPi, so I can control the lights via email. I recently bought a Google Home Mini. This is the point I started looking at MQTT and IFTTT and where I realised that these proprietry systems are not a good idea. Dead internet or router being the first issue with most of this kit you cannot switch the lights on even from inside you own phone. So the tasamota/mosquitto solution looked attractive. I bought a Sonoff RF and looked at updating the firmware. I then realised that changing the firmware will break the 433 interface (AFAIK) - this means no router no lights. Even if the Sonoff 433 does still work, it will only pair with a single wall switch, so I cannot have a switch by both doors - all these switches come with a unique code. Even if the Sonoff were able to support 433 and wifi, It still leaves folks with a problem getting stuff to talk MQTT from a phone. AFAIK IFTTT does not yet talk MQTT, you need a further bridge and configuring that bridge looks nasty. So for the moment I will stay with my 433 based kit I have voice activated lights from my phone and Google Mini to show off to my friends but the real good stuff stays on the 5 year old RPI Pedro - Apr 9, 13:23

  • The Script and ESP8266 Code for Beginners by Leo van der Hoek: So it should be possible to supply D1 mini from Nano 5V when I use 12V for Led dim and supply Nano? I cannot find current spec for this 5V, but it is AMS1117 5.0 with 0.9A current limit. I will have to try it and measure currents! Will report one of these days about my findings. Apr 9, 09:35
  • Peter Scargill The Script and ESP8266 Code for Beginners by Peter Scargill: Hi Leo The D`1 Mini and Nano clones I use both have regulators so I can use either as the source. Apr 9, 08:52

  • Darren W Sonoff TH10 and TH16 by Darren W: I have two Pi/MQTT based home automation systems - one at home and one at our holiday home. I have made them 'family friendly' by adding 433 MHz push switches to the walls alongside the normal ones. I've also got 433 MHz push buttons that are smaller that I mount elsewhere for lamps etc (panic buttons repurposed for IoT). I have a 433 RF to MQTT gateway running on an ESP8266 and rules on my Pimatic home automation system to trigger events based upon the different numeric codes transmitted via the 433 MHz push switches. This way I can control my lights/heaters/devices via my Pi with automated rules, manual push button events from a web front end (tablet/phone etc) and also from a push switch on the wall that replaces the original rocker switch. So far it seems pretty girlfriend proof - and she's not easy to convince usually! Apr 8, 23:22
  • Darren W Ruideng UM25C USB Colour Display Tester by Darren W: A great find and an excellent review - thanks Pete. I've ordered myself a couple. This always happens when I read your reviews...dangerous web site! I have an original 7 segment LED 'Keweisi' (crazy?!) USB tester and the later LCD one with the mAH counter but these are the next step up so I've bought one of each - the basic and the bluetooth one. It's great to see that you're well enough to continue with your valuable and well-respected work on this site/blog! Take care! Apr 8, 22:12
  • The Script and ESP8266 Code for Beginners by Leo van der Hoek: I am using this for PWM controlled LED lamps via WiFi and the Nano Peripheral just works fine in contrary to the ESP8266 which has interruptions causing quite annoying light flashes. So use the nano for that purpose! For ease of use I use Wemos D1mini with a supply from them as backbag in the same format as the D1 mini. Agreed for simple on/off Sonoff and Tasmota is very well packed in one case, no hustle to get your processors in a safe housing. There are a few possibilities to attach a display to this and control them fom Node-Red. So I am happy with this firmware, so keep it alive( and extend it)! Pete did you ever tried to supply the Wemos D1 mini from the Nano Peripheral(it has a voltage regulator to 5V)? Apr 8, 20:20
  • A Thermostat Weekend by IceStuff: Hello All, Nice work on the controls and displays! I have extended an existing project called Hard Thermostat with webpage controls, heating and cooling modes and supports all temperature sensors. Check it out and provide feedback would be great. Humidity control is coming. https://github.com/IceStuff/Sonoff-Tasmota/releases/tag/v5.12.1 Thanks, Paul Apr 8, 17:11

  • Ravpower the ultimate Pi UPS? by JetStream: Try out the Xiaomi ZMI Powerbank. https://www.gearbest.com/power-banks/pp_662137.html It has 2 x 5V 2.4A USB outs. It is a bit higher spec. I use the powerbank for my laptop (USB-C PD). The price drops during flash sales etc. Do Lithium cells degrade fast if kept at near full charge all the time (when used as UPS). Should we think of reducing the charge cut off threshold down from 4.2V? Apr 7, 22:29
  • Another Very Busy Week by Dean Cording: Hey Pete, I've just written a new Linux client for the Owon B35 multimeter. Apparently they changed the chip mid last year and the data transfer protocol changed which broke existing clients. I've designed my client in the classic Unix tool tradition of doing one thing very well so that it can feed into other tools like gnuplot and mosquito_pub - yep, you can publish real time measurements onto MQTT! Check it out at https://github.com/DeanCording/owonb35 Apr 7, 16:19
  • FeelTech FY6600 Waveform Generator by Peter Cranwell: Download the correct software from the vendows website. I had the same problem. The software is identified by Norton as having a virus but this is not correct. Disable NORTON and install. Cant figure out how to use some of yhe generator functions and the documentation is very poor in this regard. Pete Apr 6, 18:43
  • Big Timer by Bjarne: Can I select/change those days by an input? Apr 6, 10:17
  • Peter Scargill Big Timer by Peter Scargill: bigtimer works. dont know what scenes you are talking about, sorry. Apr 6, 09:22
  • Big Timer by Scott: Hi Peter... I love what you've done with bigtimer. πŸ™‚ I downloaded it a put it into a bunch of light flows I have for evening scenes in my house, however, once I replace the standard time node with bigtimer, they stopped working. πŸ™ I've done some troubleshooting, and I find that no matter what time setting I try, or manual inputs I push through bigtimer, I NEVER get anything out of the first (topmost) output on bigtimer. If I connect debug to the second output, I get the message as intended, at switch time, and every minute as well, and when I manually push ON or OFF through input. But in any of those circumstances, I NEVER see any output through the first output... Any ideas why this isn't working? PS - I have tried this on several different new bigtimer nodes, and even on multiple tabs and flows... I get the same results each time. Thanks for any advice!! Apr 6, 03:04
  • Peter Scargill Big Timer by Peter Scargill: The repeat only refers to the output message. You turn the timer on and off by selecting which days you want it to run. Apr 5, 23:56
  • Big Timer by Bjarne: Is there a way to change on wihch days the timer repeats, by input? For example: You send a msg with Monday = true and Saturday = false to let the timer repeat on Monday but not on Saturday. Apr 5, 21:13

  • Sonoff TH10 and TH16 by Pete: I have come to the conclusion that WiFi lighting control is unsuitable in a house with real families. Tasmota and all the various solutions are great for us geeks, but not real solutions. The acid test is could you sell the house with all this techno-stuff installed. Pedro Apr 4, 22:20
