"""Ping Alexa API to identify all devices, bluetooth, and last called device.
This will add new devices and services when discovered. By default this
runs every SCAN_INTERVAL seconds unless another method calls it. While
throttled at MIN_TIME_BETWEEN_SCANS, care should be taken to reduce the
number of runs to avoid flooding. Slow changing states should be
checked here instead of in spawned components like media_player since
this object is one per account.
Each AlexaAPI call generally results in one webpage request.
