Hi All,
Thought I would post this in case anyone else sets their eyes on a cheap P20 or P20E on eBay (or already has one) and wants to integrate it with Home Assistant.
With the assistance of Emzi there is now support for monitoring and controlling all 20 outlets, the two current reading groups, the system uptime, the temperature and the optional humidity sensor if installed.

You’ll need to ensure SNMP is enabled on your PDU and that the two communities are set to public and private (unless you wish to change those in the YAML)
Hope this helps someone!
