How does it work?

The equipment allows a direct connection with an MQTT broker through the mobile network, supporting TLS 1.2 encryption to make communication secure.

In addition to their own inputs / outputs, all GRD-MQ models can take information from Modbus slaves connected to their serial port. GRD-MQs include unique features in industrial MQTT equipment such as the ability to function as a datalogger. It has internal memory and allows adding date-time to publications so as not to lose any event if the equipment was off-line.

Automation can also be carried out locally by scripting and configuring the equipment remotely by MQTT via broker.
