It seems the issues with the device stem from the use of Lazer reflection for door status. If you do an update someday how about a Bluetooth door detector, battery powered with a gravity tilt switch to indicate complete door open. It would only transmit when open so battery life could be extended. I love this device and know that changing might be to expensive an engineering task. Thought i would throw it out as a wish list. The Bluetooth tilt switch could be a sealed all in one unit that could be a reoccurring sales item. Thanks for building a such a great tool for home automation.
