Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

and it runs fine with other sensors, that are added, but this one particular that causes issues - does not work. sensor itself does work and also runs fine on my other node red system.

thank you
