# General Information
|
|
The device is capable to register to a MQTT broker to publish data and subscribe to specific topics.
|
|
|
|
The MQTT service has to be enabled and configured properly in the device configuration via web interface (`Settings` -> `Configuration` -> section `MQTT`)
|
|
|
|
The following parameters have to be defined:
|
|
* URI
|
|
* MainTopic (optional, if not set, the hostname is used)
|
|
* ClientID (optional, if not set, `AIOTED-` + the MAC address gets used to make sure the ID is unique)
|
|
* User (optional)
|
|
* Password (optional)
|
|
* RetainFlag (optional)
|
|
|
|
