Hello, I have HAOS running with some zigbee devices and the mosquito and zigbee2mqtt add-ons. I use Enable Join in z2m and it adds a new device to both the mqtt and zigbee integrations.
The problem is that it automatically creates duplicate devices/entities in the default dashboard, one linked to zigbee and the same one linked to mqtt.
It doesn’t make sense (nor is it supported) to install ZHA if you use Z2M, and vice-versa. I am even surprised it works at all as one should have a lock on your coordinator.
