Displays the location of all sensors which have coordinates (latitude and longitude) set. They can come from the sensor itself if it is equipped with a GPS, set manually in the sensor menu or by clicking on the map while in edit mode and selecting which sensor to move.
The location is saved on the sensor object itself which means that the location will save between sessions and be shared across all Google Map widgets. Sensors with GPS positioning will have their coordinates overwritten on the next data transmission.
The color of the pin is either red or green to indicate alarm status (with red of course meaning an alarm has been triggered).
