Just upgraded from HP2019 to 2026. Migration via backup in the Homey Cloud. After re-applying the backup, both Zigbee and Zwave are not working. Zigbee can be repaired (this was also expected), but Zwave is not working still. All devices give error “Invalid Node ID: X” when trying to turn them on …

What might happen (but this is just thinking out loud) is that, while Homey is busy updating the Z-Wave firmware, that hardware was not available during the migration and contributing to your issue. On the other hand: you tried factory resetting several times and I assume the firmware update was don…

I did a full factory reset via the USB tool, but that also didn’t help. Any other ideas / suggestions? I also created a ticket at Athom, but it’s already taking them a couple of days to reply. So nothing from them yet.

I don’t have Z-Wave devices myself, so I don’t have hands-on experience. Do Z-Wave devices - similarly like Zigbee devices - have the same ‘Try to repair’ option in the device tile’s Settings > Maintenance section? If so, you might try that option.

No, they do not. Repairing Zigbee is easy. For Zwave only option I see is to re-add all devices and therefore redo all the flows I have related to those devices. Which would be a lot of work. However, based on the migration page from Athom ( https://support.homey.app/hc/en-us/articles/9302284997660-…

If you can still gather the current device IDs of your Z-Wave devices, then there is an alternative that is less time consuming. After resetting your Z-Wave network and re-pairing the devices, your flows that contain Z-Wave devices will be broken, but there is a fix. This topic describes how you ca…

I have the exact same problem with the same models 2019 → 2026, tried everything mentioned and nothing works. No response from Athom in days , so either they are working on a fix or getting ready to handle a lot of returns.

Got a reply from Support today. They suggested the USB reset as well, but with 20 min. pauses between steps for Z-wave to iniate properly. However, that also didn’t work. They requested Diagnostics Report, which I created and replied to them. Very, very annoying this!

Yes, exact same here. Also the 20 min pauses. Did absolutely nothing.

Exact same issue migrating HP2019 to HP2026. Furthermore i can not install a new device. Did someone tried to install a new device to z-wave network?
