Alarm Panel Pro

Alarm Panel Pro: Konnected Firmware Release Notes

    The Konnected Alarm Panel Pro software stack runs on the ESP32 microcontroller on the board and is updated regularly by the Konnected team. There are two "layers" to the Konnected stack: a firmware and an application layer.


    Alarm Panel Pro firmware is the underlying operating system that runs on the chip, built from the NodeMCU Lua open-source project. Konnected distributes firmware builds optimized for the Alarm Panel Pro and versioned with our own version numbering system.


    The Alarm Panel Pro application layer is developed and maintained by the Konnected team, and is not open-source. However, the application is freely distributed here and via the Konnected app.
