Since today it is not possible to connect any new device to the zigbee network.
First off:
Aqara window and door sensor, could be that the newer models are not supported… Need to try this with their hub.
Second:
EcoDim Zigbee led dimmer. Installed over 10 of these in the house…. As of today, simply adding 1 more is just impossible….
Third
Robb Smarrt switch (zigbee). Installed over 20 of those in the house, again simply adding 1 more is impossible……
It just doesn’t recognize the devices while they are in pairing mode. Rebooted homey, even killed the power a couple of times. Restarted my phone / app etc… Tried generic zigbee search instead of adding it through the app… Nothing works.
Same problem for me, which does not come from the limitation of the devices: everything was working properly for several weeks. Today, an Aqara Motion Sensor is not responding anymore. I deleted it, then tried to add it again. Impossible, I try another one, impossible. I try to add another Zigbee device, impossible. I delete another device, no effect. I always rebooted the box in between the tries. The problem comes from Homey, and I wait for it to be fixed as soon as possible. The problem is just not solved.
