MQTT Driver
The MQTT driver provides a method to publish values from a North device to an MQTT message broker. The broker stores these values and delivers them to any IoT application that subscribes to them. A range of MQTT message brokers are available, both cloud hosted and on-premises. Available for Commander and ObSys.
