I sometimes get this, only with Aqara devices when changing batteries, if I delete the device and then do a re-add it comes back. I’m using Z2M now and not ZHA but it happened in ZHA and now in Z2M
I have several of the aqara motion sensors and never had big problems adding them again and i used deconz and zha in the past (now z2m).
Just a stupid question, you see the blue light when holding for 5 seconds or press the button just a short time?
