There is an off the shelve temperature switched called the w1209 which has essentially the functions I need. However, I need it to be silent without the click of the relays. I think a npn transistor would work just as well but without the noise. Further I need it to be hard set at 36C, no buttons, no display. Additionally, the w1209 runs on 12V. I need it to run on 7.2V. If possible it should have a charging circuit for lipo 2s pack as well. Power source should be a micro USB charger. No idea if all this is possible.
