Yes, the users will get a notification in the Ecovent app when a sensor or vent loses communication with the control hub. Reasons for a loss of communication could be an unplugged sensor or low battery in a vent. The room settings would still be saved after plugging the sensor back in or changing out the batteries.

If for whatever reason the vent or sensor is still not communicating with the control hub, then the user would need to follow the instructions for resetting the vent or sensor.
