Hello,
I’ve just upgraded to zigbee2mqtt to version 2.6.3.
From zigbee2mqtt everything is working fine. But if I open the MQTT component I don’t see the entities I added after the upgrade…
I think it’s supposed to be that way. That’s the MAC address of the device, which is unique to the device and constant. That’s how HA identifies the device. doesn’t know what the light entity is called in HA.
Maybe the issue is you aren’t checking the “update Home Assistant entity ID” option when you rename the device in Z2M?
I’d start with the basics, and ensure the discovery topic matches.
In the HA MQTT Integration: Settings > Devices & Services > MQTT > Gear Icon > Configure MQTT Options > ensure discovery prefix is set to homeassistant
In the Zigbee2MQTT Dashboard: Settings > Settings tab > Home Assistant Integration tab > discovery topic set to homeassistant, and “enable home assistant integration” is checked
