The P1 USB energy meter loses connection after a few hours.

Post by Jabo »

Version: 2025-2
Platform: Raspberry Pi 3
Plugin/Hardware: P1 via Prolific USB converter
Description:

The P1 USB energy meter loses connection after a few hours. Restarting the P1 USB device, it works again for a few hours with Trixie 32-bit and 64-bit. It works normally with Bookworm. Replacing the P1 hardware and power supply has not improved anything.
