Hey all, I’ve been running into issues since a few weeks, where I cannot add any Zigbee devices anymore. It started with IKEA Tradfri which wasn’t responding anymore, and later other devices followed. I tried removing and adding them again, but it could find the device, but took too long to add them and failed. I tried a network reset, but the problem persists and devices (tried with Hue and iCasa) could not be added. I also checked the channel, where all WiFi networks (Channel 1) in the area aren’t overlapping with the Zigbee channel(tried 16 and 21). Anyone has an idea what to do? ---

Did you try using an other power device, which delivers 5Volts and 2 Amps minimum? The original one tends to deliver too little Volts in time. ---

How many Zigbee devices do you have connected to Homey? How many of those are router devices, and how many are end devices? ---

I will give that a try, thanks! Edit: Tried it with a 5V, 4A device, but still the same issue. ---

Currently nothing, as I cannot even add the first router after the reset. ---

Check this link: and see the connected devices [https://tools.developer.homey.app/tools/zigbee](https://tools.developer.homey.app/tools/zigbee) How are you trying to add devices to Homey? Are you using the IKEA Tradfri-app that connects your devices directly to Homey or are you using IKEA Tradfri Gateway-app. When I was at 50-ish Zigbeedevices the entire network began to timeout and I had all kinds of issues. So I added devices to Tradfri gateway and Hue Bridge. ---

I’ve been in contact with Homey support and apparently somehow Zigbee was not responding at all anymore after the reset. A factory reset(luckily there’s an option to keep the data) was needed and now Zigbee is responding again as it should. Thanks for helping on this topic all!
