Questions about Sonoff devices


I crack the remote open and the 2 ends, the shapes of the circuit is located. I have a piece of the electrical line and formed a loop, as a test, it is turned on /off the heating as expected.

Which device, if not Sonoff, supports Dry Contact Relay via Bluetooth LE or Wi-Fi? Since the active power is not available or required, how would I power the Sonoff device?

Background info; not versed in electronics, so my questions.
