I am interested in the outcome of this question!
So is it finally possible to add an MCP23017 to the Sonoff 4CH R2 using I²C ?
Once serial RX/TX disabled you can use GPIO 1 and 3 for I²C ?
Someone has done it successfully ?

Trigger actions from http (API) request emit from the ESP
Hi, Sorry if my question are obvious for you, I didn't know ESP easy before today ;) I would like to send IR signals when a request on an API returns a result. So my questions are : 1 - is it possible to query an API from ESP easy to trigger an action at regular intervals (like sending an IR signal)...
