Good local-only/local-first wifi thermostat? - eviltoast

I want to be able to control my thermostat from my phone, so I’m looking for recommendations for one that meets the following:

  • Works with no network access (as in, I can access it but it can’t access anywhere else, enforced via VLAN on my firewall)
  • Lets me control my single apartment thermostat (temperature, heat/cool, maybe programming but it’s okay if I have to do that on the unit directly)
  • Not hundreds of dollars
  • No microphone

Any thoughts? Really just want something simple.

Edit: I have no other smart home devices right now, if that matters.

      What’s the thermostat controlling? How is it wired up? I replaced mine with ram esphome with a temp sensor and a relay that bridges the pins when it wants to turn on. Mine is connected to home assistant but i think you can use esphome devices stand alone.

        This is probably not a useful answer, but it’s the level of knowledge that I have: it controls the heating and cooling, and it just gets pushed into the holder on the wall.
