Multichannel MQTT Relay Board

Can anyone recommend a multi channel MQTT relay board suitable for switching 240v mains loads? I’d like to automate my heating controls and this seems to be one of the better ways.

I can see that it wouldn’t be too hard to make one from an ESP8266 plus a relay board - but I’d rather someone else work out the details on how to keep the mains voltages separate to the controlling voltages - just to be safe!

Thanks!

What about a sonoff 4ch pro?

That’s a pretty good suggestion actually - thanks!

If all you need is relay control then just go for the sonoff 4ch and not the 4ch pro as it is cheaper, the pro adds stuff like inching etc so unless you need that the 4ch should meet your needs.

The non-pro also maintains earth connections, if required.
