All ikea sensors go offline

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??

Yes: Probleem Ikea Parasoll

Hi Roy and welcome!

I guess you mean Homey Pro (early 2023), right?

no :slight_smile: i had a homey early 2019 (512mb ram) and now i have a homey pro early 2019 (1Gb ram).

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.

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:

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.

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 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.
