edit1:
it’s as if the system is slow, the lights toggle on or off one by one (some at the same time) while some remain untoggled. Raspberry pi 4 with latest HA 64 bit. As if the system can’t handle the load.
I am not sure from your post how these lights are integrated in to home assistant, however notice that some of the light entities above are greyed out and this to me would suggest those entities are not currently available / communicating with HA.
How are they integrated? Do they all come from the same integration and if so are there any errors in the integrations logs?
Correct, the green out are off by a physical switch. All lights are integrated by a conbee 2 stick and zha (pre installed with the HA image) integration software. So I’ve added all lights through that software.
Well, if you take zigbee lights off power, they cannot route information for other nodes. So you are constantly “messing” with the mesh that is needed to deliver the information. So when Home Assistant tries to access the lights, the info might not always reach the intended node because one of the lights that was supposed to deliver the message is not powered. Never take Zigbee lights off the power.
