 *  Known issues:
 *  Xiaomi sensors do not seem to respond to refresh requests
 *  Inconsistent rendering of user interface text/graphics between iOS and Android devices - This is due to SmartThings, not this device handler
 *  Pairing Xiaomi sensors can be difficult as they were not designed to use with a SmartThings hub.
