M-Bus Wireless / MQTT – Converter

The HD67931-xxx-B2 are M-Bus Wireless / MQTT Converters.

They allow to publish the data read from M-Bus and M-Bus Wireless meters into a MQTT Server.
These gateways allow a fast and easy access to IoT world and they are compatible with IoT Servers ( Microsoft Azure, Amazon AWS, IBM Cloud, Google Cloud... etc and customized Servers) that support MQTT protocol.

The MQTT communication can be encrypted using TLS / SSL protocols, ensuring a SECURE and SAFETY communication.

They can use 169 MHz, 433 MHz or 868 MHz frequency on M-Bus Wireless side and they support N1 and N2 (169 MHz) or S, T and C (433 & 868 MHz) communication.

They allow to monitor M-Bus and M-Bus Wireless meters (like Amber, SIEMENS, Kamstrup, Maddalena, Sontex, etc. meters).

In relation to the order code, the HD67931-B2 can have only the M-Bus Wireless port or the M-Bus (wired) port too. ( Hybrid ).

On M-Bus Wireless side, the HD67931-B2 can manage up to 32 meters.
On M-Bus side, the HD67931-B2 can manage up to 250 meters.
