Source priority connections in file logs

[petsicola]

I have created a data log.

In the data log there are 0 values. and I want to "delete it"

But in source priority settings I can't assign the file connection.

That's the way to set prioritys for a time out value? How I can make it?

I guess you have created a data connection named file? See Data Connections. Source priorities has nothing to do with this.

Yes, I have established a connection, and on my boat, I don’t use the speed-through-water data from the Tridata. I have it installed, but I usually don’t rely on it. As a result, this path provides inaccurate values.

To address this, I have created equivalent values calculated using the SOG (Speed Over Ground), and I want to ignore the data from this path.

and use the node red value calculated. I want to put a 100000 ms priority to use only the calculated value?

How I can make this with Signalk?

If you want to completely block some data and you know node red using https://github.com/SignalK/node-red-embedded?tab=readme-ov-file#signalk-input-handler should be simple. Pass all the normal data to the next node and ignore the data you don’t want.

I'm not sure with your answer. I can´t change the priority of a path when I'm using a log file. I can use node red or program a plugin or make nothing... but... I can´t change the priority of a path if it comes from a log file... is this true?

I know how to make it in node red but I'm reporting a possible bug.

Works on my machine:

Even if the UI won't show the choice you should be able add the source reference manually and even if that fails edit settings.json manually to add the priorities:

I did a fresh installation of the SignalK server, and now I can assign priority to data sources. However, I am facing a new problem: Node-RED does not inject data when using a raw file log. It does work correctly when the file is in NMEA0183 format.

I am sending an example of the flow.
