Hi, I may have a solution to all those pairing problems. I bought Aqara Temp and Humidity Sensor and an Aqara Wireless Micro Switch. The temp+humidity sensor paired right away with Homey Pro v5 through Aqara & Xiaomi ZigBee app but then I spent hours trying to figure out how to make the Micro Switch to pair without success. I also could not pair a new Philips Hue Motion Sensor (without Hue bridge and using Philips Hue ZigBee app). Then I changed ZigBee channel under [https://developer.athom.com/tools/zigbee](https://developer.athom.com/tools/zigbee) from 11 to 18 and restarted my Homey. After that, both the Philips Hue Motion Sensor and the Wireless Micro Switch paired at the first attempt! Before choosing channel 18 I checked what channels my wifi was using for B/G/N and then consulted [https://support.metageek.com/hc/en-us/article\_attachments/115017048148/ZigBee\_Channels.pdf](https://support.metageek.com/hc/en-us/article_attachments/115017048148/ZigBee_Channels.pdf) to find a ZigBee channel as far away as possible from the one(s) used by my wifi access points. Since my wifi access points use channel 1 and channel 11 respectively, ZigBee channel 18 seemed to be my best option. Good luck, and please comment here if it works for you or not. --- _[View the full topic](https://community.homey.app/t/aqara-water-leak-sensor-and-homey/36759)._
