I am running nodered on my Synology NAS. I want to write a message (msg.payload) that arrives from a temperature sensor on my nodered server to a csv file on my Synology NAS. I have big problems with the correct formulation of the file path. Can someone give me an example of how to enter the path? …

Hi and welcome to the world of Node-Red. When you say write a csv file.... Do you mean each value would be written to the end of the file to create a csv file? So, basically: You get msg.payload with the value you want. You want to write that to a file (appending). And each entry would be sepa…

Unfortunately, even with this information on the file structure, I am still not making any progress.

Also unfortunately no-one here (so far) seems to know about the file structure on this device. Do you need to run node-red there rather than on something more appropriate?

[image] Colin: Also unfortunately no-one here (so far) seems to know about the file structure on this device. That isn't true Colin. A number of us have Synology NAS's. We are missing critical information though. Is Node-RED running in Docker on the NAS? If so, as seems likely, the OP needs…
