I believe this issue is fixed in firmware 2.08. I have been testing Hubitat zigbee groups with no binding involved (3 bulbs and 1 switch). Controlling the switch does not “mirror” these commands to the other devices in the group.
The firmware should be available on Hubitat for testing. If you have the latest driver, double click on “Update Firmware” and watch the logs for progress.
Updating various switches as I type this, and can also confirm that my zigbee group messaging is now working flawlessly between Blue switches. Well done sir!
Please mark as resolved!
