The device running HA suddenly restarted and some strang things happened after that.
All my zigbee2mqtt devices in HA got duplicated entities:
it seems like it’s an “old” and “new” entity…
The “old” keeps all the historical data and is called like “sensor.andrey_s_office_thermometer_humidity” but also has “This entity is no longer being provided by the mqtt integration. If the entity is no longer in use, delete it in settings.” message.
The new one doesn’t have the historicl data but keeps the current data and is called like “sensor.andrey_s_office_thermometer_humidity_2” (has _2 postfix)…
And all my devices behave the same way… is there a way I could resolve it without loosing all my historical data and without the need to reconfigure all my existing automation from using old entities without _2 postfix?
I also have the same issue. Most of my entités work in zigbee2mqtt dashboard but the entites are not available on the main dashboard of home assistant (they appear Greyed out) if I go to device in mqtt the devices are there but not available.
I have a similar issue, some of my devices show as unavailable - well technically its the related entities where the issues arise. I have a few ikea light bulbs which i cannot turn on via homeassistant because the regular ‘light’ entity is missing. I can publish a state set on the zigbee2mqtt topic to turn the light on or off and I can use the identify entity from HA to make the light go temporarily on.
I am quite at a loss whats going on, I got discovery turned on, have reconfigured this, purged the homeassistant topic in the broker but nothing seems to fix the issue.
I think for me there was some compatibility issue between z2m and home assistant because I was on venv and couldn’t update. So I migrated to docker and it has been working flawlessly ever since.
I am experiencing the same issue after updating from 2025.2.3 to 2025.2.4

In the dashboard-data show as unavailable, but in the MQTT Info all the data are being transfer from the broker,
