Thanks cappy. I don't disagree. I was hoping that, by not loading the driver, the sensor itself would actually not be "activated" or powered up. Sort of like keeping WiFi off, if the sensor can be kept powerered off, I'd imagine there would be some savings. Although the polling "event" only blips the CPU a small amount, the sensor device would be draining power all the time (since, I assume, it is always "on" in order to report the change in state?).

Thanks again for taking the time to write. You made very good points.
