Contact with Homey Support solved my issue. The advise was also given by Peter_Kawa (thanks). Unfortunately I was to fast with doing the full factory reset first (which did not resolve a thing btw), resulting in losing all my known devices and flows. Thanks for all your support!
**** [instructions from Homey Support]
Hi Jelle,
Thank you for reaching out to our support.
I am sorry to hear that your Zigbee is currently not working! To solve this, we are going to try to fully re-install Homey’s software. Often, this resolves issues like you have with Zigbee at the moment. Don’t worry - doing this won’t erase any of your data on your Homey.
Can you please try the following and let us know if your Zigbee is working again?
- Go to Homey Developer Tools and select “RESTART IN RECOVERY MODE” on the bottom of the screen.
- When Homey enters the Recovery mode, please open your mobile app and tap “More”. After this please tap your Homey’s name beneath your account name, and tap the “Plus” icon to add a new Homey Pro.
- Connect your Homey app to your Homey’s WiFi setup and then to your own WiFi. After checking for updates, please select “No” if you are prompted to restore a backup. (Only for Homey users who have a backup subscription) The “Options” button in grey should become available after this. Tap “Options” and select “Download full software update”.
- When this process is done, please check if your Zigbee issue still persists.
Can you please let us know if your Zigbee works after following these steps? If your Zigbee does not work after this, could you please create a new Diagnostic Report for us? You can do so by logging in to your Homey, go to Settings → General and press ‘Create Diagnostics Report’. You’ll get a unique ID, which we’ll need to view some diagnostics and dive into the problem further. Please copy this ID in your reply to this e-mail.
Thanks for your cooperation! I hope this solves your issue.
Best Regards,
Dennis
