I am a circuit neophyte, understand basic concepts but have never done a project. Am looking to automate my home heating which is electric baseboard. Am putting in a thermal mass wood heater so am aware that this heat source is not a great one but am not looking to install a different one with the wood heat project coming online next year. One zone is controlled by a programmable thermostat but with TOU power there aren't enough programs and the other zones are manual control. I'd like to be able to do it without spending a mint. I have an old android device I'd like to use as the controller. I'm thinking of simple wifi controlled relays good for up to 120v 15A coupled with wifi heat sensors in each room to turn the baseboards on and off in each zone separately. Most sources I see of plug-n-play wifi relays are somewhat expensive. I can solder, am a good woodworker, have machining experience so am good at following directions. i just don't know enough to whip this up on my own. Can someone help? Would need components and how to assemble instructions. Any assistance appreciated.
