Gateway Version 1.5.6

Stability, SMS Integration, and UI Refinement

I'd like to announce the release of v1.5.6 for the OHS_2-gateway. This update brings critical under-the-hood refactoring for better performance while introducing several requested features for daily usability.

🚀 Key New Features

  • HTTP Server Advanced Alerting System:  The Web UI alerts are overhauled. You’ll now see distinct visual feedback for Info, Warning, and Error levels, making it much easier to confirm when settings have been saved correctly.

  • "Zones Needed to ARM" Logic: This is a major security enhancement. You can now flag specific zones as "required." If you attempt to arm a group while one of these zones is compromised, the request will be rejected. There are plans for follow-up updates for authentication nodes to provide audible feedback when an arming request is rejected for this reason.

  • MQTT SMS Integration: We’ve expanded our MQTT capabilities. You can now trigger SMS messages via two new subscribe topics:

    /SMS/contact/{index}/message – Target a specific user.
    /SMS/group/{index}/message – Broadcast to an entire alarm group.

  • Config Portability: You can now download and upload simple configuration files directly through the web interface.

🎨 UI & UX Improvements

  • Cleaner Layout: We’ve removed the bottom slider for a more streamlined page layout.

  • Cross-Platform Consistency: CSS and button styles have been updated to ensure text visibility and button alignment are consistent, specifically targeting fixes for users on macOS.

  • SMS Status Checks: You can now query system status via SMS commands for better remote management.

🛠️ Under the Hood: Performance & Refactoring

A massive amount of work went into the codebase for this release to ensure the gateway remains fast and maintainable:

  • HTTP Server Overhaul: The web server code was refactored, and handlers were moved into dedicated files.

  • Memory Efficiency: Optimization of getPostData handling are faster and lighter on memory.

  • uBS Library Redesign: Introduced common static buffers and enhanced the Free and Master maps for better resource management
