I have five Sonoffs TH16 that replaced my old electric floor heating thermostats. It works pretty nicely and I can preheat my house before I arrive.
What I would like to have is a device to put into holes after old thermostats that would allow for physical control of desired temperatures and maybe a readout of current temperature. I know that Sonoff started to work with Nest but are there any other (cheaper...) options? LAN control would be appreciated.
Or maybe even we could get a Sonoff TH16 integrated into display with min/max temperature set and current temp readout + ability to change it with WiFi too? Something like Danfoss Devi Reg Smart but not for 100 bucks ;).
