MQTT.box

MQTT broker on the DIN rail

The MQTT.box is a high quality Mosquitto MQTT broker for DIN rail mounting.
It enables communication between network-capable automation components using MQTT protocol. Thanks to the second network interface data can also be made available for an additional network segment without allowing access from one network to the other.

The user management functionality lets devices located in the network to be authenticated with their own access data. With the additional configuration of an Access Control List (ACL) each user can be given "topic"-specific read and write authorization.
