How does the smart screen save energy?

When the PIR sensor detects no movement (vacant) for 20 minutes, the screen stops updating to conserve battery power.

Can data be lost if the network goes down?

No, the device supports data retransmission and stores historical data locally, which cannot be manually deleted, ensuring data integrity.
