💬 Sonoff relay using MySensors ESP8266 wifi or mqtt gateway
-
If someone wants, I create a modification to cooperate with DHT22. Data pin of DHT22 is connected to pin 5 of sonoff.
/** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0 - Henrik EKblad * Contribution by a-lurker and Anticimex, * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de> * Contribution by Ivo Pullens (ESP8266 support) * * DESCRIPTION * The EthernetGateway sends data received from sensors to the WiFi link. * The gateway also accepts input on ethernet interface, which is then sent out to the radio network. * * VERA CONFIGURATION: * Enter "ip-number:port" in the ip-field of the Arduino GW device.

I think it is an easier and more general solution to use https://github.com/arendst/Sonoff-Tasmota

@efflon Do you know how I can setup the sonoff gateway on the Vera Edge? I used the MySensors plugin to add the sonoff to the network but can't get the relay to toggle.. :/ Help is much appreciated!! Thanks!!

I am using a Vera Plus. I did not go the route of MySensors for my Sonoffs. I use the ESP Easy firmware with a slightly modified Vera plugin. Here is my BLOG post on how to do it.
https://dan.bemowski.info/2017/07/04/using-a-sonoff-with-espeasy-and-vera/You could still go the MySensors route. I just figured I'd show another alternative to this.

It's a shame that we cannot have both, mysensors and the ESP Easy stuff. There has been a project for this: https://github.com/letscontrolit/ESPEasyMySensors :disappointed_relieved:

@Jan-Gatzke It is my understanding that ESP Easy can send and receive MQTT messages, couldn't you just use a MySensors MQTT gateway if you wanted to keep it on the MySensors path?

@dbemowsk You cannot because MQTT is just a transport and not a strict data format. You can however use MySenSors MQTT + ESP Easy MQTT + a broker + node red + a controller. Node Red can do data conversions and integrate everything.
@Jan-Gatzke I was just speculating. I do not use MQTT, so I am by no means an authority on the subject.

There is no real benefit to have the sonoff running mysensors instead of other firmwares, if your controller is able to communicate over mqtt to switch on/off the relay, you are fine

@gohan I know some controller are aware of ESP Easy via MQTT. If you controller does not support this directly, you have to integrate it manually (with node red). In my opinion scenarios, where MySensors with ESP Easy frontend would be of use, do still exist.

IMHO there is one, when your controller is down, gateway is down or whatever, you could still have direct control or the light switch from a MySensors button with node to node communication.

@gohan said in 💬 Sonoff relay using MySensors ESP8266 wifi or mqtt gateway:
How do you do that if the sonoff is only having wifi?
Ah yes in that case you can't and yes there's no benefit :)
-
@gohan won't this option miss some features? :D
-
For the Sonoffs, you could wire an external button directly to the onboard button which is on GPIO 0, or you could wire it to GPIO 14 which is broken out on the programming header on most Sonoffs. Some older Sonoffs didn't have GPIO 14 on that header. Once you have a button or switch wired on, you can then change the code or do some firmware scripting depending which flavor of firmware you use.

@dbemowsk Do you know if there is a way to use vera edge / plus with Tasmota firmware instead of EasyESP??
@sam9s I have never played with Tasmota, so I have to say that I don't know. A Vera plugin would have to be coded or modified as I did with the HTTP Switch plugin to make it work if there is not one out there already. I am assuming that you looked at my blog post on the ESP Easy way.
