I searched and found some problems that look the same, but not entirely so sorry if I missed a right answer that already is giving.
Was running ZHA first and had the sonoff 01minizb running without problems.
Just changed to z2m and paired it again. It works in z2m and I can control it. Back in HA is sees the device, only the only entity it shows in mqtt is linkquality. I have some other zigbee devices that work flawless.
I have a similar problem since the latest HA update. Also all my old switches are not available anymore. This affects all my divices (Aqara and Zonoff).
I assume it has something to do with the MQTT naming changes from August?
Oh man, what a brain fart on my part… I was looking at the OS, I acctually didn’t update to the new cor yet, doing I right now and hope that solves the problem.
