I'm looking for a local only thermostat, something more "raw" than a proprietary piece of hardware. I'm thinking of basically a esp32 with enough solid state relays (I hate the clicking of normal relays) and a good enough temp sensor so that it can run standlone if HA goes down. IE, just maintain a 72 degree temp for instance. Otherwise while HA is up and running, it would be controlling those relays basically.

Something like a zigbee TRV?

What does TRV stand for?

Sorry, this is for a central air system
yea
I DON'T want any Tuya devices as I don't want to deal with that ecosystem.

It's not a tuya ecosystem if you use zigbee. But there are different manufacturers.

yea if I could find a zigbee version of what I want that would work, I also have zwave
There isn't a temp sensor included, but something like this im imagining: https://www.aliexpress.us/item/3256806004168248.html?spm=a2g0o.productlist.main.39.5e24kVGMkVGMN6&algo_pvid=4f1611a7-cf0c-499b-b4d2-28da4b419bf0&algo_exp_id=4f1611a7-cf0c-499b-b4d2-28da4b419bf0-19&pdp_ext_f={"order"%3A"960"%2C"eval"%3A"1"}&pdp_npi=4%40dis!USD!7.52!7.52!!!7.52!7.52!%402101ea7117412943728165435e06f1!12000036200859545!sea!US!882474611!ACX&curPageLogUid=ojK8O4R0DQNO&utparam-url=scene%3Asearch|query_from%3A

Unfortinately I don't have any specific or zwave suggestions.
If you go for that you probably want external sensors anyways so it could just be a separate hygrometer.

Well I really want it to be able to function on its own as a dumb thermostat if HA goes down, but that might be asking a bit much. Ideally it would have a programmable chip (ESP, arduino compat?) and temp sensor
