Thermostat recommendation (Again)

Any chance that anyone knows of a Home Assistant compatible thermostat for heating and cooling? There are a few recommendations on the forum but they are all for heat only.

And, NO CLOUD!

Really, how hard can it be to add a DS18B20 to a Wemos D1 Mini? Add three relays (heat, cool and fan), then interface it with ESPHome. I cringe at paying upwards of $200 to replace yet another failed Honeywell device.

I’m using a two way smart switch and a temperature sensor of a multisensor (primary motion) together with GitHub - hacker-cb/hassio-component-smart-thermostat: Home Assistant component: Smart Thermostat with auto Heat/Cool modes and PID control support.

Cheap and works fine. Just not having a separate display, the way to set it is thru HA interface.

Thanks- it looks like quite a project, and I will have the time this winter when my MIL moves in with us…

Specifically, what hardware are you using on the air handler? For control, I am thinking of something like HASP with a thermostat page.

I forked the project and hope that I am not too far over my skis on this one.
