Xiaomi Smart Plug EU loses power metering data every couple of minutes

[exi]

Describe the bug

I have setup my Xiaomi Smart Plug (EU) (lumi.plug.maeu01) but the power metering attributes randomly appear and disappear from deconz. I configured it in HA and the data looks like this: Screenshot 2022-09-21 at 16-15-06 History – Home Assistant

In the deconz Interface, the power metering cluster also appears/disappears randomly.

Steps to reproduce the behavior

1. Configure the Xiaomi Smart Plug
2. Wait

Expected behavior

The power metering clusters should be available permanently.

The "no longer available" message comes up every couple of seconds.

As a workaround, in the deconz interface, the plug exposes a writable attribute called Reporting Interval. The default value is 300, but setting it to "10" seems to at least prevent deconz from "forgetting" that it existed.

You might want to check https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Xiaomi-smart-plugs-not-working-correctly and update your deconz version to the latest

Thank you. I upgraded deconz to 2.18.2 and the issue went away! Did not have to firmware upgrade the device.

With the latest deconz version, I can set the reporting interval back to 300 and the measurements don't randomly go away.
