Configuring Thermostat with external sensors

Configuration
1

I using a Venstar T2000 and a few Aqara temp/humidity sensors. What I’d ideally like to do is create rules so that if one of the Aqara sensors reaches X1 temperature, the AC kicks on until the temperature comes down to X2.

I’m not sure it’s possible but it would be cool if those Aqara sensors could be averaged into a separate sensor.

Where I’m struggling really is trying to figure out which service to call to get the AC to turn on and what that automation actually looks like. Do I power the unit on and off?

Thanks in advance

would help if you shared some of your config…
Here is an example of how I did something similar but with humidity for my bathroom
Adjust the humidity into temp, and change the service to a call to your climate entity
Hopefully it helps

@lolouk44 at the time I didn’t really have a config to share, but I’ve been playing around and have found a little bit of success. It’s currently not using the second sensor, but I’ll deal with that later once I get it reliably working with one sensor.

this is a bit too complicated indeed.
Replace your trigger with:

  trigger:
  - above: 76
    entity_id: sensor.0x00158d000238c915_temperature
    platform: numeric_state

Thank you for that. Using numeric_state makes sense and worked well.
