After spending countless hours brainstorming and over a month implementing, I’m thrilled to share the successful completion of my LoRa garage door control project! 
Project Goal
My aim was to create a wireless system to control and monitor my garage door without relying on traditional connectivity options like Wi-Fi or ZigBee. Given the location of my garage, which lacks any wired connections, LoRa proved to be the perfect solution for reliable, long-range communication.
Setup Overview
I utilized the RYLR998 module from REYAX, paired with a microcontroller. The system comprises two main components:
- TX Module: Connected to my Home Assistant setup via USB.
- RX Module: Installed in the garage, equipped with a relay for the garage door button and a sensor for door status monitoring.
Both modules are configured identically, differing only in their operational mode (TX or RX), set through a simple serial terminal menu. This design allows one TX module to manage multiple RX units, each with its unique address.
Implementation Details
The signal flows through a NodeRED setup to MQTT, integrating seamlessly with Home Assistant. The configuration in NodeRED was straightforward, requiring minimal nodes to customize the message format between the dongle and HA.
Additional Features
Beyond garage door control, the system supports multiple operating modes, including:
- Relay Control: On/Off functionality.
- Switch Detection: Automatic state changes.
- Alarm Mode: Debounced contact detection.
- PushButton Mode: Single state transitions with relay pulses.
Future Plans
I’m excited to explore the possibility of making this device available for sale, allowing others to benefit from this innovative solution. Stay tuned for updates!
Conclusion
This project not only enhanced my garage’s functionality but also deepened my understanding of LoRa technology. It’s a testament to the power of DIY projects in solving real-world problems. Huge thanks to the supportive community for any advice or inspiration you’ve shared!
