OK. Thanks. It seems that I just have a hw issue with my sensor. Other than that, there are many other threads about the cases with Zigbee sensors, also some are related to wifi/zigbee network design, as they are using the same frequency band (so it could be that in some more dense living area some neighbour installes some new wifi AP (or changes the channel), and it can start interferring already. Also, might be good idea to start from Athom’s own articles, e.g. > **[Creating a stable Zigbee network with Homey Pro](https://support.homey.app/hc/en-us/articles/360019239879-Creating-a-stable-Zigbee-network-with-Homey-Pro)** > > (This article only applies to Homey Pro (2016-2019)). > Zigbee is one of the wireless technologies in Homey and is used by popular brands like IKEA, Philips Hue, Xiaomi Aqara, and others to control d... where it is also claimed, that there can be up to 15 directly connected devices, however, some people claim to have larger networks (but is some scenarios their exact network designs are not described). Also, might be good idea to check about changing the Zigbee RF channel before making a network reset… Some threads: > [@Changing Zigbee Channel?](https://community.homey.app/t/changing-zigbee-channel/39985): > > In several older posts I read the zigbee channel can not be changed.

I have about 35 devices linked, about half of which powered/router so plenty of coverage. I also found the reference to this page: On the Developers page - Tools - Zigbee there is a dropdown where you can change the channel. In my case it’s currently set to 16, which is in the middle of… > [@Zigbee network not acception any more devices?](https://community.homey.app/t/zigbee-network-not-acception-any-more-devices/49042): > > Using Homey Pro v7.0.0 i was not able to add more zigbee units. Ofter advice I reset the Zigbee network, and then i was able to add devices again. But after 16 devices I cannot add any more. Still have 3 Aquara Temp measurement devices but they is not ‘detected’. Have tried location near homey, but all the first devices where added from a more distance without any trouble. So how can I get more devices in ? The Channel is 13. I do have a Unify network with 2 AP ( using channel 1 and Channel 6… hope it give some thoughts for You. --- _[View the full topic](https://community.homey.app/t/app-pro-sonoff-zigbee/36418)._
