Cannot retrieve data from Signal-K

[itsharrie]

Hi,
I'm trying to send a delta object to signal-k using Node-Red, and subscribing to the key to retrieve the value.
Sending the delta works. Updated values are visible in the Data Browser in Signal-K.
Subscribing using the 'signalk-subscribe' node does not output any data.

The flow I use:

What should I do to make this work?
Thank you!

In your subscribe node, set the $Source to signalk-node-red

Thank you very much! It works like a charm now!
Obviously, I need to read the manual on the usage of the source property.
