I have 6 independent wall heaters throughout the house. Electric. 1 of them has little spinny knob on it and rest are hooked up to wall thermostats. I'll have to get an electrician in for the spinning knob hook up and I'll have him do all the others at once.

I want a centralized mechanism of control. The ones with the thermostats should be an easy swap out remote control thermostat.

This solution should not be limited to just controlling these thermostats. I should be able to put a remote control device on any wall switch controlling lights and electrical outlets.

It should be controlled by the same system.

The controls should be via some type of wall mounted/portable tablet (multiple control tablets, one on each floor) and should also be controllable from both my Android and my wife's Apple phones.

So does anybody have a preferred solution for this issue?
