I know the topic title is nog new on this forum, but I started a new topic since solutions did not fit my case and posts are quite old.
Today I migrated my Homey 2016-2019 to a Homey pro 2023, following the steps lined out in the instructions. After connecting the 2023, I downloaded the latest backup from my 2016-2019. Backup was installed correctly, but I ran into the Fibaro z-wave“ no valid node ID” issue that came across this forum before. The issue is that solutions point to re-installing a backup from the old Homey, or reference to a specific old version that is no longer available (most topics date back tot 2023-2024). But my issue exists after installing the backup. So I am kind of stuck. Hopefully it can de fixed without resetting devices, since there are mostly build-in dimmers.
Most migrations took place since the introduction of Pro 2023, so I don’t get the fact why you describe 2023/2024 posts, and possible fixes, as old / obsolete. Nothing’s changed right? Not Homey 2019, not Pro 2023.
I wondered what you mean by “specific old version”?
Firmware? > this doesn’t get included in the cloud backup system.
Backup? > I can’t see how that would be related.
