Device groups are primarily used to assign device types based on a particular rule. The assignment can be done automatically or manually. When done automatically, the Controller will compare the properties of the device with the existing rules. If it finds a match, it will assign the selected device type to the device. This is done when the device sends data to the Controller for the first time. The synchronization is done by the audit.

The assignment can be done based on the following properties:

• Based on source IP address - available only for HTTP Post, MQTT Server and UDP Server. For local connections, it is necessary to use local IP address (e.g. 127.0.0.1) instead of localhost. The IP addresses has to be filled in in CIDR notation (IP address, a slash ('/') character, and a decimal number describing the count of leading 1 bits in the subnet mask).
• Based on message signing certificate
• Based on MQTT topic name
• Based on device ID
• Based on receiver
  
  

When creating the device group, it is also necessary to specify the Device type. 

To edit an existing group, the user has to click on the name of the group. It is also possible to delete the group by clicking on Delete.
