This is one of the reasons I am working on an enclosure-compatible open-source version of the 2nd gen Nest thermostat. It reuses the enclosure, encoder ring, display, and mounts of the Nest but replaces the "thinking" part with an open-source PCB that can interact with Home Assistant. Nest has been pretty-badly supported in Home Assistant for over a year anyway, missing important connected features.

I've got the faceplate PCB done and working; the rotary encoder and ring working; and the display working but with terrible code with a low refresh rate.

I need to ship at the end of October to beat the retirement date. Plans to get some regular development report-outs and pre-orders are coming quite soon.

It's open source, and uses ESP32-C6 so it can be Wifi, BLE, or Zigbee, whatever software you intend to load onto it.

Any plans for 1st gen support too?

Not at the moment, as the physical layout and components are different. In theory, all the research we put into making boards and software for the 2nd gen should have some applicability to making equivalent models for the 1st gen as well.
