Maybe it suffers from interference by your (or your neighbor’s) 2.4GHz wifi signal? Thread uses the same radio and thus the same 2.4GHz frequency band as zigbee @ Homey Next, Homey uses the same chip for Thread & zigbee, called Multiprotocol, which comes with a price for you. When you either use many Thread and/or many zigbee devices, things are going south on one side or either side. Multiprotocol is considered a bad idea in hindsight, and it’s recommended to use separate hardware if you like to use both Threat and zigbee next to eachother. Below you’ll find info on how to tune the channels Note: when adding your first Matter-over-Thread / zigbee device, Homey picks the best channel to use. It’s important you’ve fixed the wifi 2.4GHz channel to preferrably 1 or 11 prior to that. > [@Advanced Zigbee Troubleshooting on Homey](https://community.homey.app/t/advanced-zigbee-troubleshooting-on-homey/115930): > > If you’re experiencing issues with your Zigbee network on Homey, here are advanced troubleshooting steps to help optimize performance and stability, especially in more complex environments: Power Supply Integrity A stable power supply is critical for Homey’s performance. An underpowered adapter can lead to instability in the Zigbee network. Always ensure you’re using a reliable adapter providing at least 2A. Power fluctuations can cause disconnections or communication failures, especially un… --- _[View the full topic](https://community.homey.app/t/some-matter-devices-unavailable/140566)._
