In isolation a temperature sensor can be “flappy”, so you may want to try and smooth the data to avoid hysteresis. I use the statistics integration to help improve the quality of my sensors.
Have a read of this for inspiration:

Using this you would create a calibrated sensor which you would use for automations as SeriousBug suggests.
At least seven years. That’s when they first demanded I provide ID. I was traveling a ton for work and using VPN so likely got flagged. My account has been in some wired shitty limbo ever since. I won’t give them my ID, and have purged my posts, likes, groups and so on. The account is nothing but a ghost now, cest le vie!
