💬 Sonoff relay using MySensors ESP8266 wifi or mqtt gateway

[gohan]

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]

A wired button would be a much fail safe option for sonoffs 😀

[Jan Gatzke]

@gohan won't this option miss some features? :D

[gohan]

@Jan-Gatzke for a sonoff there aren't many options and also a wired button you are pretty sure it would always work. 😀

[dbemowsk]

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??

[dbemowsk]

@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.

[gohan]

Can the Vera plug in work with mqtt?

[dbemowsk]

@gohan Here is a plugin for MQTT using Vera. You would still need to have an MQTT Broker set up though. I am surprised that there is not an active MQTT plugin for Vera in the plugins section. Didn't find anything when I did a search for MQTT.

[gohan]

I was just asking since tasmota works great on mqtt

I will just leave that here for other like me that wondered for hours why they could flash their sonoff, but it did not react once plugged to the main.

You need to setup your arduino with DOUT as flash mode.
Other mode will flash without errors, but the device will appear bricked.
My settings where:

[kalle]

@tripy yes, you are absolute right - you need to set the flash Mode to DOUT for flashing the newer SONOFF generation (the SONOFF's with the hidden green LED).

Hello!
Maybe someone here has a code for Sonoff RF with support 433 MHz receiver?

In my opinion, paired with a wireless wall switch, this will turn out to be quite a cheap and convenient solution for lighting control.

The cost of a set of relay and switch about 10 dollars.

[electrik]

Did you try this?

[vladimir]

@electrik Now I just read the description of this firmware. To do this, I need to understand how to work with MQTT. I hoped to find a simpler solution. Ethernet gateway is much easier to connect.:man-shrugging:

[electrik]

Mqtt Is really easy to use in fact. Just follow a tutorial to install mosquitto and you're ready to go.
It also depends on your controller of course

[vladimir]

@electrik Thanks you! Now I will order everything I need on TaoBao in China. I just yesterday learned about the existence of the Sonoff module with 433 MHz radio support and wall switches for them.

[gohan]

@vladimir what controller are you using? Most home automation controllers like domoticz and Home Assistant have a quick integration with Tasmota or EspEasy

[vladimir]

@gohan I use OpenHAB 2. As I understand it, it also integrates well with Tasmota.
