  • OWSOO 801 1080p WiFi IP Camera by TungstenE2: to be honest, no Apr 24, 07:40
  • Darren W Solar Motion Sensor Light by Darren W: Another update on this. The internal 18650 battery isn't very high capacity - even by its own chinese (often optimistic) markings - so it might be worth swapping the supplied 18650 with a decent one if anyone else intends running an ESP8266 inside their solar light. Mine is set to deep sleep for 10 minutes and then wake for 12 seconds and send temperature via MQTT. I'm finding that there are a few hours where there are no readings - presumably low battery, hence my suggestions regarding the battery capacity, above. However, it always recovers and then starts working again, but this will be a concern come winter time with fewer hours of sunlight. Where my device is situated, there's only direct sunlight for a few hours each day - great for my temperature sensor accuracy - not so great for the recharging performance. I might increase the deep sleep duration slightly although I think I will end up upgrading the internal battery longer term. Apr 23, 22:56

  • DrFragle and MrShark The Script by DrFragle and MrShark: every service installed by the script (except grafana...) share the same user and password you put in on script run, in case of mosquitto it's the admin user and password... use that, or search the net on how to remove the password or change it... Apr 23, 06:39
  • The Script by Rudy: What credentials do you mean? I entered a new password for pi, for root, and for node-red user and admin. I didn't do anything (that I know of) about mosquitto. (some time later) I did a search about passwords on mosquitto, then found the password file. There was an entry with the administrator name I entered for Node Red. There was no indication that this would also be used for mosquitto. Thank you for pointing me in the right direction. Apr 23, 01:50
  • Leo Van der Hoek The Umidigi F1 Smartphone by Leo Van der Hoek: I was just at the point I needed a new battery in my phone and found it could not keep up with nowadays apps and that lead me to order this phone.

  • Peter Scargill The Script by Peter Scargill: As Antonio says (he beat me to it) you need the admin credentials Apr 22, 08:32
  • DrFragle and MrShark The Script by DrFragle and MrShark: if you entered credentials during script running, then same credentials are used by mosquitto to authenticate with it, so just use them ๐Ÿ™‚ the ones used are the "admin user" ones Apr 22, 08:16
  • The Script by Rudy: I made Stretch Lite image on a new sd card. I did an install of Mosquitto and it works as I expected. I am able to use mosquitto_sub, mqtt-spy, and an ESP8266 board with mqtt running on it. All good. Unfortunately it does not give me all the programs your fantastic script provides. But the critical part I needed was the mqtt. I'm sure I will get the rest in time. Apr 22, 01:12
  • The Script by Rudy: I just did a new install onto a Pi3 with Raspbian lite. I am trying to test mosquitto but I am not having much success. I am very green when it comes to Linux. I don't know what to expect from this script. Should Mosquitto be configured to run as is or is there additional setup that I must do first? I tried an initial test with ssh with the following result. (and on the Pi with lower response) pi@Broker:~ $ sudo /etc/init.d/mosquitto start [ ok ] Starting mosquitto (via systemctl): mosquitto.service. pi@Broker:~ $ mosquitto_sub -d -t hello/world Client mosqsub/850-Broker sending CONNECT Client mosqsub/850-Broker received CONNACK Connection Refused: not authorised.

  • Node-Red-Contrib-Timeout by Mike Honda: my mistake. here is what I am trying to do -- i have a garage door status hooked to node red. I want to start the timer when it gets the message that door is open. and after a set time (let's say 30 minutes) unless timer is cancelled (by garage close notification) it will send an alert. any thoughts if I could use bigtimer or timeout node for this functionality ? Apr 19, 19:49
  • Peter Scargill Node-Red-Contrib-Timeout by Peter Scargill: Ignore my comments about Auto, I was thinking about BigTimer... Apr 19, 17:07
  • Peter Scargill Node-Red-Contrib-Timeout by Peter Scargill: Yes, Timeout WILL timeout on restart of Node-Red. The input STOPS the timeout. I just attached a default Timeout node to debug and tested this. After 30 seconds it timed out - that is the intended operation. Pete Apr 19, 17:06
  • Node-Red-Contrib-Timeout by Mike Honda: Tried with auto-restart, same issue - timeout fired at restart of node-red server (without any input given to node) here are versions -- node-red-contrib-timeout - 1.1.1 node-red - 0.19.5 on Ubuntu 18.04.2 LTS (on a regular computer , not raspberry pi) Apr 19, 13:21
  • Peter Scargill Node-Red-Contrib-Timeout by Peter Scargill: Check the auto option. If you are still having any issues, describe exactly along with Node-Red version, BigTimer version and what you are using this on (Raspberry Pi ?) etc. Apr 19, 09:59

  • Hantek 2-in-1 Scope + Meter by Desmond Downs: "A small volume of the non-profit grip by a single hand; The suspendingstand was designed to support multi-angle adjustment;" I think the misunderstanding about being a non-profit group is most likely caused by a bad Chinglish translation of one of the features.

  • DrFragle and MrShark The Umidigi F1 Smartphone by DrFragle and MrShark: i love my pocophone f1... very fast, as big as my previous oneplus one (which lasted 4 years to me, 1st time in my life...), an impressive battery life (i can reach 2 days if needed, and FOR SURE i can have a VERY HEAVY day and reach night with a single charge)... ๐Ÿ™‚ Apr 16, 08:27
  • Peter Scargill Big Timer by Peter Scargill: Don't just look at msg.payload on the outputs when using the debug nodes. Look at the whole message - lots of information. Pete Apr 16, 08:26
  • Big Timer by James: Wow. I can't believe that 4 years later you are still answering comments. Impressive. Not to mention the famous node! DISCLAIMER: I am somewhat new to Node-Red... I would like to adjust certain settings of BIGTIMER via the input. Is there a chart, or any documentation that delineates what each field is called? Forgive my ignorance. In other words, let's say I would like to set the "Off Offset" time by sending a message to the node's input. Is this possible? I see that I can send "on" "off" and "auto" as payloads in order to manually override the timer, or reinstate it. VERY COOL! But if I want to do the same for other parameters, how do I ascertain their respective variable/ msg.parts names? Thanks for creating such a versatile node and especially for the continued (and unprecedented) support. Apr 16, 05:52
  • Darren W Solar Motion Sensor Light by Darren W: Just an update on this. My solar light (as above) is still working great at our holiday chalet - it survived the winter and sub-zero temperatures. I bought several more of them on the strength of that and am currently testing my adapted version with added WeMos D1 Mini (ESP8266) and Dallas DS18B20 temperature sensor and deep sleep / MQTT to give me an outside temperature reading - hopefully without the need for powering it. The DS18B20 is on a short cable so that I can mount it away from direct sunlight. Testing this week at home, and if all goes well, it'll be deployed in place of the standard 'dumb' unit to be a motion sensing light with integrated MQTT outside temperature sensor ๐Ÿ™‚ Apr 15, 22:24
  • Pikantekip Big Timer by Pikantekip: Hello, Thank you very much for Bigtimer. It works very well! Only thing I would like to see is if it can output (4th output maybe?) its own current state like auto, manual/temp on/off etc. This for other nodes to be informed what state it is in. Thank you again for this great node! Apr 15, 20:17
  • Peter Scargill Sonoff, Tasmota and Alexa by Peter Scargill: Raspberry Pi 3 B+ which, trust me is well up to the job of running that, Blynk, MQTT, Grafana, my VPN and lots of other stuff all at the same time. Indeed, if only the RPI guys would increase the RAM, the sky would be the limit. As it stands I'm no-where near to using the PI to full capacity. Apr 15, 13:55
  • Sonoff, Tasmota and Alexa by Nick Marino: Guess I am a little confused how this all comes together. Where are you running Node-Red from? Apr 15, 13:27
  • The Summer Begins by Smithy: If you load up the front page of Iteads website there's 5 images displayed at the top of the page. The first image of the 5 showing the Sonoff Basicr3 shows an "MQTT Enabled" logo Apr 15, 08:13
  • Big Timer by Nick: I had to add an extra check state to check for motion after BigTimer. It would be nice to have a 4th Output to output only when input is received or to have a check box within the BigTimer config to select this as an option. Please let me know if there is currently that option. Apr 14, 18:02
  • INA3221 v INA219 by Glenn Pearston: Thanks, my INA3221's are taking a slow boat from China and am hoping to not add to the delay by having to wait until they arrive to order some resistors. Thanks again Glenn Apr 14, 16:07
  • Big Timer by Nick: I figured out how to get the instant output (move connection to the second output node of BigTimer. The problem I now have is that it triggers an output when the timer kicks in. Is there a way to deactivate the output for the time and only trigger an output when there is an input? Apr 14, 16:04
  • DrFragle and MrShark The Summer Begins by DrFragle and MrShark: indeed, that's not their use case... but for me, i used a 2 relay shelly which fitted perfectly in my 503 wall mount box, nothing viewable from outside, immediately working for my already functioning up/down blinds, then easily connected to wifi... an sonoff dual would have been a "diy" solution with lots of cons, 1st of them it's HUGE, and no power consumption monitoring... shelly uses power monitoring to detect when my blinds are full open/close, and automatically turn power off... 0 programming/hacking, 0 ugly stuff on the wall... shelly and sonoffs have different uses, most similar, but each with its pros and cons, and the price is the smaller of their problems, as i just explained... sure, i'll never mass deploy a setup of shelly for everything, just because their expensive, indeed... but i'll never do the same using sonoffs just because they're cheap, as they need more "cure" and hacking and are just too big for many uses... Apr 14, 15:49
  • Peter Scargill Big Timer by Peter Scargill: Manual override doesnt work when a day is not selected... because it is an override, overriding the times. If the timere is not active on a given day there is nothing to override. Apr 14, 15:45
  • Peter Scargill The Summer Begins by Peter Scargill: You mentioned the most important thing - the Shelly is WAY more expensive than the Sonoff - if all you want to do is turn a light or even a heater on and off, why spend 20 Euros on a Shelly 2.5 when you can spend under 5 Euros on a Sonoff. Even Shelly One is just shy of 10 Euros. Apr 14, 15:38
  • Big Timer by Nick: First of all, you created an awesome node. Thank you. I have a situation where I would like to only trigger floor lights to turn on when motion after dark. Is there a way to trigger the output to be sent instantly when an input is detected? I don't want to modify the output. I just want to trigger a resend of the output. Currently, I need to create a variable from BigTimer that I check against when I detect motion. In my attached image, the first row is where I save a variable to trigger on or off based upon the timer. The third row shows my implementation using this variable. I don't prefer this approach because the variable saving steps aren't inline with the automation. The second row is my attempt to put the BigTimer inline with my automation. The problem is that the output is not sent past BigTimer. I also don't want BigTimer to trigger the lights on without motion. Do you have a solution for this with the current BigTimer node? Apr 14, 15:37
  • Peter Scargill INA3221 v INA219 by Peter Scargill: I don't know the size off the top of my head. If the resistors I used surface while I'm unpacking, I'll leave a note in here. Apr 14, 09:29
  • Big Timer by russ: love your work. not sure where i have gone wrong though. i am (trying to) use bigtimer to control a device based on off-peak times. so power off from 7am to 11pm monday to friday, but with a manual override. (which will ultimately be controlled by presence of excess solar power). but....if i have only mon-friday ticked, then i cant turn on for the weekend, and i found even a manual override on doesnt work. any hints as to how i can achieve this? (i thought a second timer for the weekend might work, but dont seem to be able to configure for 24hour 'on'. Apr 14, 08:44

  • DrFragle and MrShark Raspberry Pi Pin Layout by DrFragle and MrShark: seen those but not added to comments because i think they're some way multiplexed or use a resistive matrix, instead of having directly exported pins like my 1st 2 items (the 3rd one i think it's like yours...) ๐Ÿ™‚ usually when prototyping you need few buttons, each directly connected to gpio... even hardware debounce like the capacitors in 1st item can not fit your sketch, if you're doing software debouncing... well, of course it depends on each case scenario ๐Ÿ™‚ Apr 13, 12:29

  • DrFragle and MrShark The Summer Begins by DrFragle and MrShark: nice addition to a best selling product, but... BUT... it's always the same product... while other competitors succeed to put 2 relays WITH power monitoring on both in half a sonoff basic size, itead increases even more its box size... and the only addition is just an http api... no REAL new products, only little improvements on a well established lot of old ones, maintaining the same price, which is good, of course... most of the innovation today is done by Shelly, but they cost twice as much as the equivalent sonoff devices in half the size of a sonoff, usually... this has just been announced Apr 13, 06:15
  • Peter Scargill The Summer Begins by Peter Scargill: Well, that's no big deal for people like us using MQTT. I sometimes use Tasmota but recently I've been using my own ESP-GO more frequently - no longer do you need Alexa compatibility if using Node-Red thanks to the Amazon Echo node.. lovely and works a treat. Apr 12, 16:15
  • Peter Scargill Big Timer by Peter Scargill: I assume you are referring here to a BigTimer in manual timer override mode - which does work in seconds unless you use a suffix for minutes "timer 2 mins" or timer "1 min" etc... Current version of the timer is 2.19 from December 2018. Only the first letter of the suffix is used so "m" will do. Apr 12, 13:40

  • PIVPN and PI-HOLE by Vince: Thatโ€™s another package to install, configure and maintain. Since itโ€™s not part of PiVpn it wouldnโ€™t get any updates automatically and potentially might be broken if pivpn updates a service it depends on. Here is my logic, if someone decides to use pivpn script it means they are not fluent in Linux to configure openvpn themself and shouldnโ€™t be messing with any additions. I prefer to run pivpn on separate machine to minimize the risk of braking dependencies. By the way, what are the use cases for home automation that require Vpn to be on 24/7 ? Apr 8, 14:34

  • ESP8266 and ATMEGA2560 Mega Board by Ulrich: Hi Bob, thank you for your helpful comment. I'm going to flash the ESP8266 with ESP-Link Firmware. The mode button has to pressed during flashing operation, right? Apr 5, 10:33
  • PIVPN and PI-HOLE by Vince: Changing the port does not add any security whatsoever, you might as well stay at default setting. Within 48 hours of creating DNS records the whole world will know you are running some sort of server. Bots will start scanning port range immediately and will find yours. Yes, by changing port you will avoid all stacks from amateurs, but itโ€™s not who you should worry about. Iโ€™m kind of paranoid (I was hacked twice before) when it comes to server security and here is my solution: I run multiple rpi servers in (openwrt as a firewall router, web server, mqtt/nodered, domoticz, vpn client to work network, nas, plex, syslog, openvpn server) each dedicated to do its own task. All of them are On 24/7 except Vpn server which is connected through a relay, controlled by gpio in domoticz, with on/off by telegram bot. Any time there is for need remote access to my lan I would send a message to Telegram, wait a minute for Vpn server to start, connect, do what has to be done, shutdown the server. Ones cracked Vpn server has unrestricted access to your lan, it should be well secured, but since I donโ€™t posses skills to customize iptables keeping it off is my way of securing it. Apr 3, 18:25
  • Bob Green ESP8266 and ATMEGA2560 Mega Board by Bob Green: Ulrich, The little slide switch should be set to Tx3 / Rx3, the DIP switches are set to the 'special solution' as shown in the table above. On the picture you posted those highlighted pins are attached to the ESP8266 and, if you are running ESP-link on the ESP8266, you do not need to re-define them. I have one of these boards and I have flashed the ESP8266 with the latest version of ESP-Link. I am currently evaluating its stability by periodically powering it down and then powering it back up to make sure it performs reliably. I have sought information on several websites and the consensus is that this combination of ESP8266 and MEGA perform reliably. Apr 2, 23:10

  • ESP8266 and ATMEGA2560 Mega Board by Ulrich: Hi Peter, I'm struggling with the communiction between ATMega2560 -> ESP8266. ESP -> ATMega works. The little onboard switch is set to RXD0/TXD0. I wrote a sketch for a standalone access point. Returned data from the ATMega has to go to the ESP8266. On the screenshot attached I defined a red area. Do these pins belong to the ESP8266? If so, I could experiment with different pins, define them as Tx/Rx including softwareSerial.h and connect them to pins of AtMega. I do not find any board description on the internet. As I'm not very experienced in this case, the advice of an expert would be very helpful! Ulrich Apr 1, 14:08
  • Peter Scargill Bakeey M30 Smart Watch by Peter Scargill: Well, my view for what it is worth, the watch has AVERAGE charge life, nothing special. It is NOT that good in bright sunlight, but in other lighting, it is fine and the display and general finish are very good. I'd have preferred a better strap, but then it is hard to know which way to turn... metal straps look great but the cheap ones tarnish quickly. The flexible strap with the M30 still looks nice after weeks of use. Being able to get a fuss-free refund or repair is very important - sadly more and more companies go out of their way to distance themselves from customers. I'm glad Banggood sorted your refund efficiently, Andy. Apr 1, 13:16
  • Bakeey M30 Smart Watch by Andy Cox: I ordered one last month but arrived with a faulty screen. All credit to Banggood for a quick refund once I'd provided them with video evidence. Never did get to see if the watch was actually any good though. Apr 1, 12:24
  • Bakeey M30 Smart Watch by Dave Thompson: > the time on the M30 wanders off Yours is a lot better than mine,, 1min/day slow Also, the app cuts phone run time in half, I always kill it after syncing time Mar 31, 21:01
  • Garry Hayne The Thermostat Continues by Garry Hayne: Thanks for that, very easy to interface with InfluxDB (Obviously ๐Ÿ™‚ ) Mar 30, 18:30
  • The Kitchen Sink by Joachim Baumann: Did this project come any further than the state described here? I would be very interested in it. Cheers, Joe Mar 30, 12:17
  • DrFragle and MrShark The Thermostat Continues by DrFragle and MrShark: he transforms tubes and metal sheets into drones, bikes, motorcycles, dune buggies... it all seems so easy how it does, but sure he plans everything, and it's impressive the results with basic tools and materials he gets, nonetheless... i like a lot the first minutes of his videos, when he collects materials: he has shelves of wheels, shelves of accelerators, shelves of fuel motors, shelves of brushless motors, shelves of tubes, shelves of whatever thing you can imagine... he has shelves of everything, even shelves of shelves! ๐Ÿ˜€ Mar 29, 06:48
  • DrFragle and MrShark The Thermostat Continues by DrFragle and MrShark: as you said, do what you can with a drill or dremel, then go with a file to refine edges... in case of displays or other devices with a flat panel larger than the part which goes inside the box, even not perfect borders are ok as the face panel will cover them... Mar 29, 06:44
  • Bob Green The Thermostat Continues by Bob Green: That video made me smile, he is certainly a creative fellow! His Dremel cut illustrates what I was saying. I was trying to suggest ways to get a nice straight cut with square sides, something that a display might fit into. I'll have to look at more of his videos. Mar 28, 23:37
  • Peter Scargill Big Timer by Peter Scargill: Not undocumented. Mar 28, 21:42
  • MrBorg Big Timer by MrBorg: Oh so there are an undocumented options called "repeat" - that should be set off by default... Mar 28, 21:20
  • Peter Scargill Big Timer by Peter Scargill: You must have repeat setting on in which case you would get an output every minute - turn it off if you don't want that. Mar 28, 21:09
  • MrBorg Big Timer by MrBorg: Sorry but I haven't read all incident above - theres a loooot. But I'm experiencing an odd behavior of my Bigtimers. When bigtimer is turned on I get an update of state update each minute even if I'm using the first connection from the top (right side) - this I would expect from the last connection on the right side. Is my installation wrong in anyway or is the Bigtimer broken? Mar 28, 21:00
