Script web link CSV value to an item?

I have a La Crosse Gateway GW1000u - it auto uploads temp data to a web portal - where I can access the CSV file. ( hopefully anyone searching for the same might find this page in the future

All I want is the current “Probe Temp ©” out of the CSV. Line 1 is headers, line 2 is latest data, cell 3.

I’ve read that many sites and pages and guides, and have no idea what any of it means.

API link to my CSV

Can someone please help, or show me an example I can learn from ?
I just want to be able to able to see the Pool temp in my Basic UI :cold_sweat:
I’m running a Qnap 559ii Pro with OH2.4 app package installed, so my options to use python are limited, as the QNAP is locked down, and its old so I can use docker. Happily entertain and read anything anyone send though!!

Thanks to anyone who can help me.

Have you tried node-red
I got your latest data with a simple flow:

[{"id":"4ecb0b70.e290a4","type":"inject","z":"6250dce3.505294","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":140,"y":460,"wires":[["ffc8196.c81af68"]]},{"id":"ffc8196.c81af68","type":"http request","z":"6250dce3.505294","name":"","method":"GET","ret":"txt","paytoqs":false,"url":"","tls":"","persist":false,"proxy":"","authType":"","x":320,"y":460,"wires":[["f5d047a3.71e1e8"]]},{"id":"f5d047a3.71e1e8","type":"csv","z":"6250dce3.505294","name":"","sep":",","hdrin":true,"hdrout":"","multi":"mult","ret":"\\n","temp":"","skip":"0","strings":true,"x":520,"y":460,"wires":[["fc18f5e0.ee35a"]]},{"id":"fc18f5e0.ee35a","type":"function","z":"6250dce3.505294","name":"","func":"msg.payload = msg.payload[0];\nreturn msg;","outputs":1,"noerr":0,"x":680,"y":460,"wires":[["223134b9.01aafc"]]},{"id":"223134b9.01aafc","type":"debug","z":"6250dce3.505294","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":880,"y":460,"wires":[]}]

Look at this, it can give you a hint:

If it does not work, I think you should rely on external script (bash,python,php…whatever suits you).
