- From the devices tab, you have added them to the system? (arrow should be blue) - Yes
- Users, did you specify any devices for the user you are logging in with? If yes, did you also add the P1 meter? - No, but I did now and they are there!
Thanks!

I have a Pi3B+ newly set up (as the old zero was no longer supported by domoticz) connected to a P1 Meter and connected as slave to the master domoticz (running on Windows). All P1 device show up on the Pi3B=+ (in "devices" and "utilities") and are showing up in "devices" on the master domoticz ...

After defeating Microsoft for not allowing wifi on a server OS, your script works like a dream on my Solax X3!
Thanks for sharing!

Hi!
Did you get anywhere with these lamp holders?
Got a few of them as well.
They are branded here as "Mengshen". Also checked the circuit board and it says "www.zsgeer.com.cn", but that site seems unreachable.
