I cannot see a reason why, upon sending a 20.0 command to the tempMax item, an HTTP GET is not performed to http://192.168.0.103/control?cmd=event,changedummy=20.0. @rlkoshak, does anything look amiss to you, or should an issue be opened here?
Nothing looks wrong to me. I’m thinking something must be broken in making sure both bindings get the command. The Exec test adds more evidence, though there could be a whole lot of other things that could go wrong with Exec.
@paveleremin, when you trigger the switch do you see anything in the log at all from the Exec binding? You will not get an error in the log if the command failed but you should at least get something like "Exec binding executing " if the binding is being triggered.
That will confirm whether the problem is just with the HTTP binding or with the core.
The new exec 2.0 binding widths very differently than the 1.9 binding. Three is a recent PR with some improved documentation for how to say it up and use it but personally I would recommend sticking with the 1.9 version for now. At least until the PR with the improved docs makes it into the baseline.
