I use variables for username and password too and it occurred to me the other day that I could, and probably should, make the Tasker logic a little smarter and adjust the URL based on whether I’m on the LAN or not. That way I don’t have to go out to myopenhab.org when I’m home and can talk to OH directly. I haven’t spent the time on it yet but will update my original posting or create a new one when I get the chance.
Thanks for posting!
