LEDVANCE Smart+ GU10 zigbee

Hi there,

i have 24 of those and they are driving me crazy.

They are nested in groups and some of the are:

staying (actually turning off and then on again) on after an off command
blinking green
being slow

In the past weeks they also

got stacked in a different setting from the others (different color, different dim etc)

All the other lights (hue/ikea on zigbee are fine).

all addressed by HA skyconnect and ZHA

Any ideas on how to solve those?
