Hi @Stefan DB

/data is a path that survives any firmware update. It's a good place.

If you have the SSH on LAN enabled, use an utility like WinSCP.

Not clear how I get acces to the cerbo via WinSCP.

Cerbo doesn't show up in the list off network devices

Cerbo and the computer with WinSCP must have IP address in the same network. For example Cerbo 192.168.10.12 and the computer 192.168.10.15.

Cerbo must have the SSH on LAN option activated. This option is available after you enable the Superuser access level in Settings - General.

You enter Cerbo user/password pair in WinSCP.

Then all should work.

Ok this works but my file is not there.

Used "/data" but this is clearly not ok ... tried "/data/filename.csv" also but also fault.

Maybe that condition that leads to that "writing into the file" node is not met.

Use some simple condition, that you know it's always true, to trigger that.

And see if it writes something.

Are there any logs to verify that?

found the file but the owner is not "root" but "nodered"

this will be the reason why i don't see the file when logging in with root
