Nest - Change active thermostat from HA

I have a Nest Thermostat and 2 add on sensors on different floors of my house. Using the nest protect integration I was finally able to read the temperature of the add on sensors.

The missing piece which I am inquiring about is the ability to set the active thermostat from Home Assistant. Just this feature alone without the ability to even read the temperature would be a HUGE benefit as the Nest app only allows you to schedule the active thermostat based on large blocks of time.
