Zigbee gateway integration

[tigi]

I added a new zigbee smart plug recently and while it's values gets updated in the LM zigbee app the linked group addresses are not.
Only when I manually click on 'device status' in the zigbee app the group addresses are updated.
The linked group addresses all have a tag 'groupread' for replying to group read requests (https://forum.logicmachine.net/showthread.php?tid=18)
The other group addresses for the linked zigbee devices all get their values updated correctly.

What can be the problem and the solution?

Thanks!
