Fixing flows isn’t needed any longer. Just replace the ‘old’ device ID('s) with the new one('s).
.
Alternative: I added every zigbee device to it’s own matching < group > device.
This way, I only have to change the group member (old device for new device), flows stay unaltered.
Disadvantage: zigbee devices depend on < group > app
For sensors: if you use the Zone activity in flows, you can also replace devices without needing to modify flows.
