Firmware for the MySensors RFM Gazpar Module, an IoT energy sensor designed to monitor French Gazpar gas meters in real time.
This module connects to French Gazpar gas meters to track gas consumption in real time. Gazpar meters emit a pulse every 0.01 m³ (10 liters), which this module detects and transmits wirelessly to your home automation controller. The module reports gas volume every minute and battery status every hour.
This product is designed for the French market and integrates with Gazpar smart gas meters installed by GRDF (Gaz Réseau Distribution France).
MySensors is an open source framework that simplifies building your own IoT sensors and actuators for home automation. It handles the low-level communication protocols so you can focus on your project's functionality. MySensors integrates with many popular home automation controllers including Home Assistant, Jeedom, Domoticz, OpenHAB, and more, making it easy to add custom devices to your existing setup.
