Got a fix today from Homey support and that worked for me!
If you currently do not have a backup of your Homey Pro (Early 2019), could you create a new backup first? For this process we will need a backup from a state where it already works, which is on your old Homey.
After making a backup of your Homey Pro (Early 2019), please ensure that it is no longer powered on to avoid network conflicts when restoring your Homey Pro (2026).
When you do have a backup of your Homey Pro (Early 2019), could you install an experimental update to your Homey Pro (2026)?
You can enable experimental updates by going to Homey Developer Tools , select your Homey Pro (2026) on the top-left (under your user icon), then enable the slider “Enable experimental updates”
After enabling the experimental updates, please follow these steps on the Homey Mobile AppGo to More (…)
Go to Settings
Go to Updates
Tap Check for Updates
Install the experimental update (12.13.0-rc.4)
More information about experimental updates can be found in the following article: https://support.homey.app/hc/en-us/articles/12199889665308-Enabling-experimental-updates-on-Homey-Pro.After the update is installed and your Homey Pro (2026) has rebooted, please reset your Homey Pro (2026), using the pinhole at the bottom by holding it for 30 seconds until the Homey LED ring is pulsing red.
More information about resetting this way can be found in the following article: https://support.homey.app/hc/en-us/articles/7261843930396-Resetting-Homey-Pro-to-factory-defaults.After that, set up your Homey Pro again, after setting up Wi-Fi again please wait 20 minutes before continuing
After that, restore the backup from your Homey Pro (Early 2019) again.
After restoring the backup, again wait 20 minutes before continuing to use the device. This way we can ensure that the Z-Wave network is initialised correctly.
