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. iOS 15,4 Homey Pro 7.3 6.11.2.893 ---

Installed over 20 of those in the house Sounds like you just reached Homey’s Zigbee limits. Read [this article](https://support.homey.app/hc/en-us/articles/360019239879-Creating-a-stable-Zigbee-network-with-Homey-Pro) for more information. ---

Thanks, Didn’t realize the limit was this low… Every device shows as “router”. However, I have 23 zigbee devices directly connected to Homey. Plugged the device further away in the network and they started pairing again. ---

> [@Seandemy](#): > > I have 23 zigbee devices directly connected to Homey. 15 is the max. All others are or should be connected via a router / a few routers.

That is the way to go; Pair new devices near the router closest to where the new device is going to be mounted ---

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. ---
