3. Operation
3.1 Transport Mode
Sensors are shipped with a plastic battery insulating pull tab that must be removed before
the operation.
3.2 Default Operation
While in default operation, the device will send a join request message after booting for a
minute. After joining successfully, the device will detect the ambient light every 5 minutes.
When the sensor detects the change of ambient light, it will send a status change message.
