oh-knob-card

The problem

Knob card sends multiple commands when trying to set a new thermostat setpoint.

I configured an oh-knob-card to control Thermostat_Setpointcooling item on a CT100 thermostat. When changing the setpoint in the UI I see multiple commands being sent in the events.log and the setpoint ends up only changing by one degree.

Expected behavior

I expected to see a single command sent after the knob was released and the command would be wherever the knob was set at when released.

I was able to run a send command in the console to change the setpoint by multiple degrees and it worked as expected, setpoint immediately changed to the new value.

Additional: I've seen this behavior using safari on iOS and firefox on Linux. It doesn't appear to be browser related.

Sending multiple commands tracking movement isn't a bug, though a useful enhancement could be made to optionally manage that in more detail.
