Sonoff Dual only usable with app?

My 3 sonoff dual arrived last week.

I tried one out last weekend and can now control it wiht the APP provided.

I miss the features to control:

- via REST

- via MQTT

Is this device only usable with the APP or do I miss something?

Writing my own firmware seems to be difficult to, as the IO is routed through a seperate MCU and the protocol doesn't seem to be open.

Would you know how to best control temp/humidity with Sonoff? I need to link 4 devices (humidifier/dehumidifier/heating pad/cooling device) for an incubator. A TH16 pair with 2 Sonoff duals? (can they actually be paired?) Thanks!
