Overview
The Wattsense Bridge is an open, interoperable IoT gateway designed for on‑premises building data collection and local protocol conversion. It enables rapid installation and retrofit of building equipment and redirects field protocols locally to BACnet IP, Modbus IP or MQTT for integration with existing building supervision systems.

The Bridge User Console
A web-based interface that connects equipment in a few clicks via a growing device library (1,500+ devices). Key capabilities include:

• Remote configuration of equipment while storing data points locally
• Real-time data view and logs for operational insight and troubleshooting
• Configuration wizard — no coding required to set up devices and automation rules

Main functional highlights

• Remote configuration via the User Console
• Real-time data monitoring and logs
• Local redirection of LoRaWAN and other field data to BACnet TCP/IP, Modbus TCP/IP or MQTT
• LoRaWAN to BACnet/Modbus conversion for local BMS access
• Option for local MQTT redirection (Ethernet)
• Support for deploying apps and cloud functions available on Tower variants (Bridge focuses on local/on‑premises use)

Licensing & pricing summary
Licence model: one-time payment for Bridge.
Point structure example: 100 points (Bridge) with options for unlimited points on specific offers.
Supported local functions: connectivity, remote configuration, LoRaWAN to BACnet/Modbus conversion, BACnet TCP/IP scan to MQTT.

Device & ecosystem
The Bridge integrates with an equipment library and partner ecosystem to connect meters, sensors, HVAC, lighting, BMS and many LoRaWAN devices. It is suited for retrofitting legacy BMS via protocol conversion and for quickly deploying local smart‑building use cases.

Use cases / example deployments

• Convert LoRaWAN data locally to BACnet IP for a BMS to control HVAC
• Collect local sensor and meter data and expose it to supervision systems via Modbus/BACnet/MQTT
• Small/medium building retrofit: connect meters, sensors and controllers for automation and monitoring

Technical specifications
