There is a DDF for this device but only enabled for some versions.

"comment": "DDF for device firmwares at least above 0.0.0_0022, paired with xBee I fw 0x26400500 / xBee II fw 0x266f0700 and above", "matchexpr": "R.endpoints.includes(0x15) && R.endpoints.includes(0x1F)",

Do you have endpoint 0x15 and 0x1F on your ? it's visible on the GUI. Else try direclty to edit the DDF devices\xiaomi\xiaomi_sp-euc01_smart_plug.json

replace the "eval" line by "eval": "Item.val = Math.round(Attr.val / 10);"

Thank you, I've already fixed it in similar fashion. I just wanted to report it as a bug since it has been introduced in 2.18.2.

So the patch is working ?

DDF is working as expected, my Sonos SL is consuming 5W

So the patch is working ?

My working solution was to alter the value right in the HA for the sensor.

I wanted to do it via ddf file within Home Assistant however there is no mapping for the addon container to this day to my knowledge (if you know any other way how to do it). I will try to locate it right within container and alter it via DDF file and let you know.

The wiki has a few remarks for the device in https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Xiaomi-smart-plugs-not-working-correctly from what I understand the plug should work with the DDF when it's updated to the recent OTA firmware. The older Xiaomi firmware is a bit messy.

I'd suggest to also update the ConBee firmware to 0x26780700 as 0x266B0700 is older when the needed one (with a backup first).

Side note: The following PR adds the "known issues" section with a link to this wiki in the DDF in https://github.com/dresden-elektronik/deconz-rest-plugin/pull/6386 to show up in https://dresden-elektronik.github.io/deconz-rest-doc/devices/xiaomi/xiaomi_sp-euc01_smart_plug

I have the exact same case, originally reported as a bug of the deCONZ addon to Home Assistant, but since that is only wrapping the deCONZ software the fault is in the underlying deCONZ rather than the addon itself.

https://github.com/home-assistant/addons/issues/2679

Power values increased with a 10x after the update, and was "fixed" by rolling back (to deCONZ 2.17.1 from 2.18.2)

@manup so we can close this issue?

[carentius]

All my Aqara Smart Plugs measuring with a factor of 10. Rolling back to 6.15.0 resolve the issue.

@manup so we can close this issue?

I have not have time to test ddf since I'm away from home atm but I will do it this weekend.
