Supported functionality

This integration interfaces with the kernel’s power management system to detect whether the Raspberry Pi is receiving sufficient power. It creates a binary sensor that indicates whether your power supply is adequate (normal state) or if there are voltage issues (problem state).

If issues are detected, consider upgrading to a higher quality power supply that can deliver stable 5V power with sufficient current for your Raspberry Pi model.
