I'll second the suggestion for Wemos D1 Mini, as I've just started to play
around with them for thermostats / override buttons for my heating control
system. I'd recommend looking into the micropython firmware for them too -
it makes development easy and fast. Look for an IDE (loose term) called
uPyCrft - very fast turnaround to test your code.
In just 100 lines of micropython I have a program that will connect to my
wifi, connect to my heating controller (TCP connection) and send and
receive commands. It auto-reconnects to the wifi, and in my 100 lines, I've
got exception handling to reconnect to my TCP connection too, very quick
and easy.
Regards
Simon
