I made this project during a couple of weekends. Something could've been done better — but it is what it is. Pull requests are welcome.
This app takes messages from ajax security modules and sends them via MQTT, making possible to use Ajax devices in your Homeassistant or Homebridge, save telemetry to InfluxDB, etc.
It doesn’t use Ajax cloud services, doesn’t require internet connection and doesn’t expose any data outside of local network. However it requires special hardware module to interface Ajax wireless protocol (see Required Hardware section below).
- uartBridge
- FireProtect

All your Ajax devices will be accessible in HASS thanks to the MQTT discovery. If you don’t need this feature, you can set hass.enabled config value to false.
- Ajax uartBridge to interface wireless Ajax devices. Costs about $30 (where to buy).
- USB-UART adapter. Any cheap adapter will work fine, I am using this one. Costs about $1.
- Connect TX pin on bridge to RX pin on USB-UART adapter
- Connect RX pin on bridge to TX pin on adapter
- Connect GND pins together
- Connect +5V pins together
- Plug the adapter into USB port on your computer
I will use the PM2 as an example, but you can use any process manager (upstart, systemd, etc).
