With the EOS technology it is possible to place EOS devices in groups. This will give the ability to let EOS devices work together. It will let them share information of their sensor for movement and daylight savings (DLS)*.
Below a video that illustrates how to set EOS devices in a group and let them share their sensor information.
*Note that for Sensor sharing additional packages may be required. You may click here to see instruction on how to install packages on EOS devices.
