In node red I can connect to the server and get the output but in one large block, apparently with all the formatting line feeds and carriage returns removed.
In the debug window I see the same unformatted text output all blocked together until I mouse click over the text and the formatting reappears - but not in the dashboard! What is happening here?
How do I get the formatting to appear correctly in the dashboard?
I'd also like at a later stage to take out parts of the data and place them into a database, if I can get the line feeds back then should I be able to extract features from this listed output?
Is the program source under your own control? If so then you might consider replacing it with a node red flow, then you run the whole thing in the pi.
If you do want to keep using the program then it would be much easier to decode if you changed the program to write to mqtt, or alternatively reformat the output to be in JSON form.
If you cannot modify the program then show us what you see in a debug node when you feed the result there.
Th original program is not of my making and is no longer supported by the original author, and I don't think I'm up to converting it ... 'you changed the program to write to mqtt, or alternatively reformat the output to be in JSON form.'!!!
The code generated by the debug window is

The above doesn't appear to be all of the output but it is representative of what I see in the debug panel and the dashboard.
Note that it is a string with newline characters embedded (the little right angle arrows). Not sure whether these are CR or LF or both. I suggest using a Split node to split it into a sequence of messages, splitting on the newline character. Then you can use a Switch node using a Regex testing the start characters (so whether it starts with Thermostat or Temperature or whatever) and sending each one to a separate output. Then in each output you can extract the value and do what you want with it (send it to a chart or a guage or a text field or a database or whatever).
