I was able to get this to work by using the device handler from here: https://github.com/digitalgecko/mySmartThings/blob/master/devicetypes/digitalgecko/hue-motion-sensor.src/hue-motion-sensor.groovy
Will test it out and report back. However, I looked at the execution location and it is Cloud - no doubt because of the DTH. Any way to have local processing for this?
