I try to do this from LUA script.

How can I update setpoint value without triggering device change event?

I tried CommandArray['UpdateDevice'] - it works with Selector Switch etc. but when I try to use it to adjust setpoint value it immediately triggers device change.

Also is there a way to get info about current state of nvalue ...

I'm current Vera user and joined Domoticz community to have integration with LG AC, Samsung TVs and iRobot - all of wchich Vera doesn'n support :/
But for now non of this works for me in Domoticz too :)

@Olinek2 unfortunatelly I'm unable to send you PM, since I am new user here - I installed LGAC ...
