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.

    Recently I went through some pain with this myself. Had a full Heatmiser setup with wireless receivers in every room and 2 manifold controllers for our underfloor heating on two floors.

    The devices ate batteries like nothing I’ve seen before and regularly dropped off the network and didn’t send call to heat signals properly, so I decided to switch out the thermostats for cheap ZigBee temperature sensors.

    I then ordered a relay board from AliExpress with a baked in esp8266 cheap and flashed esphome onto it. These replaced my manifold controllers

    After trial and error, I now have my heating system run by esphome and home assistant. It has been faultless! Will probably reinstall the Heatmiser kit if I sold the house though
