Well, I suppose since most thermostats have wifi now, they sort of count as gadgets... lol

I need a programmable thermostat recommendation. But...
  • must use 4-wire connection only - NO C-Wire!
  • One box simple DIY solution - no 'watch this YouTube' to make brand X work
  • I don't need the wifi... but do need programmable time cycle features
I tried posted on Reddit /HVAC but the mod's there are all 'pros' that delete any/all home user install or requests for recommendations... asshats!

What are you trying to do? By programmable do you mean 5/7 day and occupied/unoccupied?

If you just want a dumb temperature switch there are lots of options. There are mechanical stats that require no power themselves and just open or close a circuit for example.

Or you could get a line voltage stat if you controlling something 120v.

A normal t-stat needs a common wire because it's powered itself by 24v AC.

Your system and any possible changes also come into play here. I simply had my HVAC guys make a recommendation (assuming you have a relationship with an HVAC company).
