Multiple doorbells to one thermostat or Multiple thermostats to one doorbell

If pairing multiple First Alert VX1 or Ring Doorbell Cameras in a location with multiple thermostats, individual doorbells can be linked to individual thermostats.

If a single doorbell is linked to multiple thermostats, both thermostats will receive the notification.

If multiple doorbells are linked to a single thermostat and a doorbell is pressed while the thermostat is already streaming from a different doorbell, the second doorbell will be ignored until the initial stream ends.

There is no maximum number of pairings. The limiting factor is network bandwidth.
