Xiaomi Zigbee Power Socket - incorrect wattage reported + voltage missing

[amit-nz]

The problem

Upon updating to 2022.10.5, I have found my Xiaomi Zigbee power sockets are over-reading by a factor of 10x (i.e. if it’s got a 200w load, the Electrical_measurement entity reports a 2000w load). I checked the update history/logbook, and this started immediately after the update:

I posted about this issue on the HASS forum, where another user with the same issue has mentioned that the Analog_Input entity is reporting the correct load.

Please let me know what log(s) I can supply to help diagnose this - it appears nothing is actually broken, just the values are messed up - so no "errors" to speak of. A few values (per my screenshot above) are showing zero or unknown, but as far as I know these have never worked so not too concerned with them.

@amit-nz can you go to the device page and reconfigure the device please?

FYI, if reconfiguring doesn't work (it should), you can either read the ac_power_divisor attribute on the ElectricalMeasurement cluster (and new reports will be correct again):

Or re-pair the plug to fix the issue. That should also add the voltage measurement and the total energy consumption now (which integrates with the HA energy dashboard).

[amit-nz]

@dmulcahey no go on reconfigure, but @TheJulianJES's solution to read the ac_power_divisor attribute has worked, wattage now reported correctly, but no voltage. That is not a big deal for me. I will re-pair them later on as I'd like to get them integrated into HA's energy dashboard, but for now this is sufficient. Thanks for your assistance.

[dmulcahey]

Ok I’ll look at the reconfigure part.

Fixed by rejoining the device. Enhancements may be made in the future to prevent this.
