@michaelmell Dear Michael,
I’ve now successfully integrated the Xiaomi Mi SmartPlug in OpenHAB 3. This was not possible with the ZigBee binding of OpenHAB 2 or 3, but with the help of ZigBee2MQTT. I’ve written down all my steps in this post: Setting up Xiaomi Mi SmartPlug (Zigbee) with OpenHAB 3.
Regards,
Heiko
Note: I’m not using ConBee II stick - mine is a CC2531.
