Could you make it even cheaper? Absolutely, yes! You can make it even cheaper, but the point is that you don’t have to spend money on an expensive off-the-shelf product from a company that may or may not get bored of providing their service–or at the least expect you to buy a new product every few years. You can make a thermostat. They’re not incredibly complex and if you want to check out the code I’ve created to operate this thermostat, check out the GitHub below.
This thermostat is made to work with Home Assistant using what they call "helpers", but it isn't required for functionality.
I’m not affiliated with Home Assistant–or anyone, really. I just like this stuff and I’m trying different things. I’m not a pro at home automation or the technologies just yet, but this is all part of me figuring all of this stuff out, and regardless of whether it’s the best approach, my approach to things generally works out in the end.
