LoRaWAN BACnet gateway uses Raspberry Pi CM3+ for building automation

A few years about we wrote about BASpi I/O Raspberry Pi HAT compatible with BACNet, a data communication protocol for Building Automation and Control Networks, also known as the ISO 16484-6  standard, and used for HVACs, lightings, elevators, fire safety, and other systems found in buildings.

But if you’d like a turnkey BACnet solution based on Raspberry Pi, UK-based Innovelec‘s DINGO LoRaWAN BACnet Advanced Gateway/Server may be easier to integrate into your building’s electrical installation and also offers low-power long-range LoRaWAN communication.

The LoRaWAN BACnet gateway runs the DINGO stack that includes auto-configuration, alarms & events, file access, BACnet Object
Access, Remote Device Management, LoRaWAN Gateway, and LoRaWAN Network Server. The gateway can handle over 10,000 BACnet objects, but a 10 objects license is included by default.

Typical applications for the DINGO LoRaWAN BACnet gateway include BMS Building / Campus Management Systems, Smart Agriculture, large scale / metropolitan data logging and control, environmental monitoring, street lighting control, car parking systems, traffic monitoring & management, waste management, and more.

The building automation controller is available now, and Innovelec is taking orders starting at £742.75 (around $1023 US) for a system with a 1/4 wave antenna and 10 BACnet objects. The product page lets you select a different antenna, the number of BACnet objects, as well as the optional expansion modules listed in the specifications.
