P1 USB cable with Prolific serial chip	Works	Cable recognised after plugin update; systemd port access needed fixing Saved copy I have bought a P1 cable, attached it to the RaspberryPi and installed the software. After the software successfully is installed I rebooted the RaspberryPi. During the boot of Homebridge I see that the P1 software is loaded, with 2 warnings about the node version and the Homebridge version.

Maybe an issue in hex/base64 encoding? see next example: app is showing : 13:13 ==> 66,83 Wh in Eve, homebridge-p1 calculates 401Wh 13:23 ==> 42 Wh in Eve, homebridge-p1 calculates 252Wh 13:33 ==> 39,67 Wh in Eve, homebridge-p1 calculated 238Wh [code] Excerpt saved from GitHub on 2026-10-22.
