I’m a new Home Assistant user so be gentle with me! I do have some experience of programming and Home Automation in general (having a Vera Edge and Amazon Echo & Dot).
echo SETCH 144 | telnet 192.168.0.XXX 31339
from a command prompt on Windows 10 and couldn’t get it to work so I looked for alternatives.
I downloaded ncat (the portable version, a single executable file) from here:
and used it like this:
echo SETCH 114 | \path\to\ncat\ncat --send-only -t -n 192.168.0.XXX 31339
It only works with the “–send-only”, the command hangs otherwise
I also found this about the protocols
Hope this helps someone
