If I restart HA, the scenes often don’t come back as they should. They kind of exist if I look in the scenes settings, but they have a different name (eg ‘bright’ instead of ‘Kitchen Bright’) and they also say “this entity is no longer being provided by the mqtt integration…”
Once I restart the Z2M addon, they then come back as expected.
I don’t have this issue, no, even though I am using Z2M scenes. Are you running the Mosquitto and Z2M add-ons? There have been some complaints about auto-discovery in general not working correctly after a HA restart, but I haven’t seen those on my setup. (I am using external VMs for both the MQTT broker and Z2M though, but that should not make a difference in theory,)
