Another usage is to measure energy cost for something that does not provide energy or power values.
I was just about to implement this, when I looked in the code to see that it is fully supported as of the current state of the binding.
Add a new state machine with the following config:
create these simple rules:
I tested this with my ZwaveReading Light. When the item “ZwaveReadingLightSwitch” is turned ON it will send 60W as on.
The machine will then calculate energy consumption as long as it is on until another value is sent. When turned off I send 0. If you want dimmed values, you can send 20, 30 , 40 etc.
rule "BridgeOmaticPowerTest"
when
Item ZwaveReadingLightSwitch changed to ON
then
logInfo("Omatic", "TestMachine send command")
OMTestMachinePowerIn.sendCommand(60)
end
rule "BridgeOmaticPowerTestOff"
when
Item ZwaveReadingLightSwitch changed to OFF
then
OMTestMachinePowerIn.sendCommand(0)
end
