Although the Hub has a built-in battery to account for any power outages at your home, it should be plugged in at all times. If your Hub temporarily loses its power source and has depleted its battery from 8.5V to 7.5V, a Trouble Condition will appear in the app and your Hub will enter Low Power Mode.
Within Low Power Mode, your Hub will decrease LED brightness, turn off the Z-Wave controller, and make other concessions to conserve power for life-saving operations until plugged in again.
If the power at the property had been lost but is now restored, plug the AC adapter into your Hub and allow up to 72 hours for the backup battery to recharge. Once the battery is fully charged again, the "Panel Low Battery" trouble condition will disappear.
If your Hub is showing a Panel Low Battery status after 72 hours of charging, please follow the steps below:
- Make sure that the power outlet the Hub is plugged into is working and isn't controlled by a switch.
- Confirm the AC Power cord is securely connected to the wall outlet and plugged into the rear of the Hub.
- Open the battery compartment and ensure the black battery switch is turned to the ON position away from the battery wire connection, as shown in the picture below:
