Please consider adding mop320

[ecranbleu27]

Just bought a mop320 (double outside plug) but can’t add it whatever way available I tried (address + key or Meross cloud). Anyway, thanks for the great job !

Hello @ecranbleu27,
The mop320 has been reported in various issues in the past but in general, it was correctly integrated. Maybe there's some new strangeness with latest firmwares that should be addressed. Do you have any log ? I guess you should enable debug logging (from the top-right 'burger menu' in the meross_lan integration page) so to have more insights about the detection/registration process.

Hello. Thank you for your reply.
No log yet as I can’t connect to Meross cloud.
I have this error when I try to connect with my Meross login & pwd.
ConfigEntry.init() missing 1 required keyword-only argument: 'subentries_data'
The mop320 is in the Meross app and in Apple Home.
As a workaround, I used HomeKit to HA to have it discovered but the power consumption is missing.

Ohh..so it might be a more general issue (compatibility with HA core) in device configuration.

Hello @ecranbleu27,
Which version of meross_lan are you on? The error is likely an indication of incompatibility with HA core.
That particular fix was added in v5.4.2.

Hello @krahabb. I’m on v5.4.1… I’m going to check why I didn’t have any update notification. Thanks for your help.
