mcqwertyPlease could you try:
and see if this turns your valve number 3 on. Replace 'VAL03' with 'VALxx' where xx is the number of the valve you want to control and "ON" for "OFF" to turn off. I doubt this will work, but its worth a try.
Good luck, and please let me know anything I have missed or messed up. I plan to try to keep this google sheet up to date with findings from this thread and also work to add documentation for understanding the status updates sent from the IntelliCenter.
First, I tried port 6680 per the latest from kyleaa but I was not using a reverse proxy.
PuTTY did not like that port at all.
Next I used port 6681 and tried your test command. Valve 3 did not move and this was the response..
