Ok, this is how I solved it (no HA core backup restored or w/e):
Update node-red to 16.0.2
Install Samba addon.
Set password in samba
Go to a file explorer (windowskey+E) and enter in the search-bar \YOURHOMEASSISTANT_IP_ADDRESS
Enter the username & password you just set for samba
For me, this shows:
For me, I went to the “backup” folder, and looked for the latest .tar file (sort from new to old) that was larger than 10KB.
Open that folder
Open “configs”
Now you see this folder
Open the .flows.json.backup with a text-editor, and copy the contends (this is your node-red config!).
Save it to a new file - called “flows_backup_thank_mfing_god.json”
Now open Node-red in Homeassistant
import flows
Done.
I’m not 100% sure this is all latest changes, but I think it’s at least 98%
Hope this helped some1
