xbee2mqtt

xbee2mqtt is a gateway daemon that connects XBee wireless modules to MQTT brokers, enabling IoT device communication through a publish-subscribe messaging protocol. It allows remote monitoring of sensor data and control of digital pins on XBee radios via MQTT topics.

Key Features

• XBee Monitoring — Listens to a coordinator XBee connected to a serial port for incoming messages in API mode.
• Remote Pin Control — Supports setting digital pins LOW or HIGH on remote XBee radios via MQTT commands.
• Topic Mapping — Configurable routing of XBee messages to specific MQTT topics using patterns and placeholders.
• Duplicate Filtering — Ignores duplicate messages within a defined time window to reduce network traffic.
• Value Pre-processing — Includes filters to process sensor values before publishing to MQTT.
• Daemon Operation — Runs as a background service with start, stop, and restart capabilities.

Philosophy

xbee2mqtt follows a straightforward bridge approach, translating XBee API frames into MQTT messages with minimal configuration, making it suitable for DIY IoT and home automation projects.
