Hello community!
I recently removed the Hue Bridge and migrated all devices such as motion sensors, light bulbs, and switches to Zigbee2MQTT. I created groups in Zigbee2MQTT so they could be controlled accordingly via a switch. Because it annoyed me that I also had to create an “all lights” group, in which I would have had to add all light bulbs individually, I deleted the groups in Zigbee2MQTT and created them directly in Home Assistant instead. Unfortunately, this led to the issue that the lights would turn on one after another rather than simultaneously (this worked correctly with the Zigbee2MQTT group).
I therefore deleted the Home Assistant groups again and recreated the groups in Zigbee2MQTT. I always made sure that the entity IDs remained the same so that I would not have to adjust my automations and switches. Now, however, something has happened such that a switch which normally should control the lights above the dining table is now also switching the living room light and the outdoor lighting. This is not limited to a single switch but occurs with all of them. The same happens when I turn the groups in Zigbee2MQTT on and off: other lights turn on and off as well, not only those within the respective group.
However, the groups in Zigbee2MQTT contain only the intended light bulbs, and according to the GUI, the bulbs are assigned to the correct groups. What could be the cause of this?
