OPEN HARDWARE

Systemd daemon that wraps the Bosch Sensortec Environmental Cluster (BSEC) library to extract calibrated temperature, humidity, pressure, gas-resistance, and IAQ readings from an I2C-connected BME680, then publishes them over MQTT.

Much more accurate than the native Home Assistant BME680 module — the BSEC fusion algorithms handle drift compensation and the indoor air quality index in ways the open-source path can't replicate. MIT-licensed.
