TCP Binding - Send Command, Parse Response Into Items

Add-ons Bindings
1

I am having issues understanding how to use a TCP binding to retrieve data. I have a TCP device that I connect to, send the string ‘T0’ and then it returns lines of ASCII. The line I am looking for is in the format:

00 01 YYYY XX.XX

where YYYY is a unique serial number and XX.XX is temperature.

I can’t figure out how to set up the Items to use the binding to do that. I assume I will actually have to set up four items and just parse our the serial number I care about for that item, but I can’t seem to get it to send the T0 command and get the results back, even into a String.

Anyone have an experience with that TCP binding?

Some updates. I have figured out how to send the command and get the response, but it appears I am not transforming the data correctly. I assumed that it was due to the fact that I am getting multiple lines back, but the data “breaks” at strange places.

Here is what the data looks like when I connect manually:

T0    <---- This is my command input
1      <---- Junk line back I need to ignore
00 10 1AF8 22.43      <---- Actual data I want
>

And here is the OpenHab2 config:

mss.items

String MSS70 "MSS 70" (gMSS) { tcp=">[192.168.2.70:3001:'REGEX(.+([0-9][0-9].[0-9][0-9]))']"}

mss.rules

rule "Pull MSS Data"
when
        Time cron "0 0-59/2 * * * ?" 
then
        MSS70.sendCommand("T0")
end

Here is what I see in events.log
