The SHAC has this inbuilt explanation for the SetCBusMeasurement function... " -- Set temperature and units of channel 1 of sensor 1 on the local network to 25.2 degC SetCBusMeasurement('Local', 'sensor1', 1, 25.2, 0) -- 0 is the units parameter as per chapter 28 of the C-Bus documentation" does anyone know what C-Bus documentation this is referring to? I am looking for the "units parameters" for kW and kWh and have been using trial and error (I am upto 40). Any ideas ? thanks
