LNXlink is a Linux companion app that seamlessly integrates your system with external applications like Home Assistant. It uses MQTT, a lightweight messaging protocol, to enable real-time data exchange and remote control capabilities.
Features:
- Sensors: Automatically discover sensors that monitor and control the system.
- Home Assistant: Uses MQTT Autodiscovery to create entities and shows if update is required.
- No sudo required: No need to be root user to install and use, unless used on server setup.
- Easily expanded: Any new module is automatically imported and custom modules can be added.
