Ich möchte auf dem Filesystem eine Datei speichern. Ich verwende die node "write file" und bekommen eine Meldung, dass ich keine Zugriffsrechte habe (Error: EACCES: permission denied, open .......). Was muss ich machen wenn ich eine Datei auf dem File-System ablegen will ?
hallo,
du darft nicht nur einen dateinamen angeben, du musst auch den pfad angeben und ich wuerde dir empfehlen, eine sd-karte einzusetzen und die daten dort zu speichern.
ich benutze dazu eine mysql-datenbank.

That is covered by https://www.victronenergy.com/live/venus-os:large#q1write_read_file_gives_erroreaccesspermission_denied:
Q1: Write/read file gives "Error: EACCESS: permission denied'
Since Venus OS 2.90 and on wards, Node-RED no longer runs as user root, but as user nodered. This means that the Node-RED flows are only allowed to access files and directories that are owned by the nodered user. These files typically start below /data/home/nodered/. So modifying the storage location to something like /data/home/nodered/storage.txt ought to work.
hello,
i have some good ideas to make victron products better and some are possible, to use node-red to realize them.
i have also some problems with venus-os which make things, which it should not make like ignoring configured limits!
but i have no posiblity to contact the right persons at victron to discuse my ideas and the problems with things, which should not happend.
can you hellp me with that?
goodby
Best way is to make a community post describing the ideas and tagging me. Our development is largely community driven, and quite a few of my colleagues are active here too.
