Thermostat Data Packet

When UC701 controller is paired with or connected to the wireless thermostat (WT401) and the communication mode of the thermostat does not include LoRa, the thermostat status will be reported via UC701 controller. The UC701 can forward the following information from the WT401 thermostat:
  • Battery Level: transfer when the thermostat turns on or the battery level changes;
  • Battery Alarm: transfer when a low battery alarm is triggered or cleared;
  • Button Event Report: transfer when the corresponding button is pressed;
  • Device Status: transfer when the thermostat turns off.
