i had a homey early 2019 with the ikea app. after a few days the parasoll door sensors stopped working. when the door was closed , the keep “saying” the door is still open. After restarting the app in my homey or disconnecting the battery again the cam online again. since yesterday i have a home pro 20219. And i noticed that there is no conntection with my 3 doorsensors and the temperature mesuerement. After restarting the app they are online and after a few minutes they are offline again… is this a know problem?? ---

Might be influencing performance: Is your 2.4GHz wifi channel set to a fixed channel? If no, set it to preferably 1, 6 or 11 If yes, check if the zigbee channel is set to one with the least chance to interference. > ![Screenshot_20210413-165254_Chrome~01](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/9/29f6698638a638a6c12d8e2167f46b2960c6e466.jpeg) ---

Thankx! My 2.4 network was set to “auto”. I changed it to 11. Hopefully this works. If not, how/where van i change the zigbee channel in the homey? ---

Changing the wifi channel is the easy way, but the zigbee channel can be viewed and changed here: [https://tools.developer.homey.app/tools/zigbee](https://tools.developer.homey.app/tools/zigbee) It might be possible some devices need to be re-paired afterwards. Or, when you don’t bother to start over with zigbee, just reset the zigbee implementation. The procedure finds a quiet channel automatically. Keep in mind close neighbours’ wifi signals can interfere sometimes. ---

> [@Roy\_V2](#): > > i had a homey early 2019 (512mb ram) and now i have a homey pro early 2019 (1Gb ram). Ah, ok. So you had to build the Zigbee network from scratch. Beside the tips from @Peter_Kawa , I hope you followed also the support article [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) for Homey Pro (2016 - 2019). What should also be taken into account is that end devices (battery-powered devices) should be added at the installation location to the Zigbee network. Changing the Zigbee channel of Homey after you have already set up a Zigbee network is not recommended by Athom. At least that’s what an Athom support employee once told me.
