Description

When setting up Better Thermostat with three Tuya devices and one of the three is used as temperature sensor, the current temperature reports 0.

Steps to Reproduce

1. Setup BT with Tuya thermostat devices A, B and C.
2. Use thermostat A as the temperature sensor

Expected behavior: The current temperature reported by thermostat A is read correctly (external_temperature_sensor -> state)

Actual behavior: The current temperature reported by thermostat A is reads 0.

I noticed this with mine as well. If you choose your own thermostat as a temperature sensor it does not take the local temperature - it takes the temperature offset instead. So it will show 0 or -1 or +2 or whatever the offset is set to. If you change the offset value in your thermostat, you should see it change in Better Thermostat. I solved it by just ordering more temperature sensors and using external ones - that's what it's meant for anyway as it isn't great measuring the rooms temp right next to it's heat source.
