Groups are the key to device management in DME. Every device is member of at least one group. Settings, schedules, RSS feeds, etc. (in the following simply called settings) should be applied to devices through their membership of groups.
A system of group hierarchy ensures that devices that are member of multiple groups are given the correct settings in case there is a conflict between settings in the different groups.
This group system has a number of advantages. First of all, you can be sure that all devices are given a set of settings. Secondly, it makes it easy to manage large numbers of devices because new devices are automatically assigned to groups. The groups that you create are smart groups, meaning that group membership is determined by the current properties of the device. If the properties change, the device may also change groups. For instance: You decide to create a group for each country where your company has offices. The country affiliation is based on the SIM card of each device. If a device in the country group France is given a new SIM card issued in the UK, the device will automatically switch to the United Kingdom country group. For more information, see Adding groups.
The group membership of a device is evaluated every time properties are changed for the device after a system information synchronization.
If you want to see which devices are currently member of a group, go to the Devices tab and click the Advanced button in the filter bar. Then click Group filter, select one or more groups, and click Search. The members of the selected group or groups are then displayed in the Devices tab. See Advanced filters.
On this page, you see a list of the groups that have been created, along with its type (described in the section Adding groups) and the number of devices in each group. The group Default Settings is a system group that cannot be removed.
