thanks for clarification.
So my system seems to be up to date.
Still the question why the smart button is not useable?
I have now a Hue Smart Button and a Hue Dimmer Switch V2 connected to the conbee.
The Dimmer Switch V2 works fine and can be assigned to groups. But i am not able to assign the Smart Button to a group, it is not listed in the ‘availalbe switches’ list.
In deconz it is recognized correct as ‘Hue smart Button’.
Phoscon has the issue probably. In that case you can’t do a lot but wait for @de_employees to respond. Phoscon is closed source so only they can help.
Given their response time I suggest you switch to using the Hue essentials app as that is able to leverage deconz rules and configure devices that way.
