Support for devices which need an install code for pairing

I use a Conbee-II coordinator-stick for my Zigbee2MQTT home automation system and it would be nice to pair (for example) a BOSCH smart plug to it.

But I fail because this device requires to be paired with an install code.

Zigbee2MQTT supports this install codes, but as I read in the forum, the Conbee-II stick didn’t.

Is this information correct and if so, is it planned to extend the firmware of the stick?

Moved to correct area.

No clue where you got that from. Conbee support it with deconz.
