I’d love to see a direct integration of this too. The only thing I’ve found so far is an option to flash the Sonoff with firmware that you can then get to work with an MQTT bridge. But it does mean that you need to setup an MQTT bridge in your network somewhere and that’s just another thing that can go wrong.
The RF bridge does not natively support IFTTT at this point, but if iTead ever get that working, that would be another option, albeit not a great one.
