Sonoff and Vera

[nicomedia]

I'm completely new to MySensors, and I don't understand how it works 100%. I wanted to connect sonoff relays to my Vera, but I don't know how the connection works: it says on the website that the vera needs a serial or ethernet gateway, but why would I need that when the relay already has WiFi? Do I need to create multiple devices and configure them as a separate gateway for every relay? Thanks for your help.

You would have to run the MySensors firmware on your Sonoff (acting as gateway) presenting and controlling the relays in the device.

I haven't tried this myself (haven't got any sonoffs) but in theory it should work.

Which one? The only firmware for the esp8266 that I can find is for gateway only, but the sonoff also has an onboard relay... Do I have to modify the code or something to make it work?

You have to find out which ESP-pins that controls the relays and modify the gateway sketch using the Relay example as a hint.

@hek Sorry for being annoying, but I don't know anything about MySensors. I know that the relay is controlled by GPIO 12 and is active high. Do I flash the esp8266, the RelayActuator.ino or do I merge the two together? Thanks so much for your help.

You will have to merge them.

@hek Thank you so much! I've been able to write my code for the relay. The problem is that it doesn't compile because it finds errors in the mysensor.h library. How can I fix this? Did I do something wrong?

@nicomedia I stumbled on this doing a google search. Just wondering if you are still trying to get your Sonoff's working with your Vera controller? If so, I have written a blog post on the subject. It uses a different firmware called ESP Easy and an HTTP Switch plugin on the Vera rather than MySensors. but it works rather well for me. Here is the link to the blog post:
https://dan.bemowski.info/2017/07/04/using-a-sonoff-with-espeasy-and-vera/
I use this in conjunction with some MySensors wall switches that I built.
