Another way to view Data is on the Maps Page. Located on the Maps Page are little pips to show where your devices are. Normally these pips will show a Device Icon and nothing else.
By default, a device's pip will have no tracking enabled, just a Device Icon.
Instead of this Device Icon you can track a sensor's data, allowing a number to be quickly displayed whenever entering the Map Page.
A device with tracking enabled will instead display a sensor's value. If a temperature sensor were to be tracked, the Device's pip will display the latest temperature reading.
To track a sensor, navigate to a Graph Page. Click on the gear icon in the top right then on the popup click on Track Sensor.
Finally select the sensor to track on the drop down and press Select. Now the Sensor is being tracked and can be viewed on the Device's pip in the Map View Page.
