Problem pairing with Nous A1Z Smart Plug

Hello everyone,

I have a Conbee II together with the ZHA integration up and running.
I already have connected 12 aqara humidity sensors to HA which are working fine. Because I ran into some connection issues due to the large area of my hous, I bought 4 Nous A1Z plugs to extend the coverage.

According to Nous Smart ZigBee Socket (A1Z) Zigbee compatibility the A1Z is supported on ZHA.

My problem is:
When I try to pair one of the plugs, it starts blinking and even after HA tells me, that pairing and configuration is done, it’s still blinking (which is not normal).
I can turn the plug on/off for a few seconds (<10s) but then it stops responding. The other seconds still work fine. Sometimes it even pairs the same device again (within the 3 minute maring that the conbee is in pairing mode). After that I can control that device again for a few seconds.

I tested deconz to see if it’s a problem with the device, but it’s not. They are working fine, even after over 24 hours. And when in pairing mode, they stop blinking as soon as the pairing is done, so there must be something going on in the python zigbee implementation.

Here’s a log, I hope somebody can tell me, what’s going on: hass.log · GitHub

I’m more than happy to provide more information or do things in my HA system.
