This is a bridge interfacing Jablotron alarms to HomeKit. It doesn't use Jablotron's online services that are high-latency and limited in functionality, but connects to the alarm system locally. It exposes:
- Alarm device itself
- Sensors (motion, contact) as HomeKit sensors
- Pseudo-buttons for manipulating alarm state without user confirmation
- JA-121T interface module for Jablotron alarms
- Linux-compatible USB-to-RS485 converter, e.g. based on FTDI/FT232RL (e.g. Digitus)
- A computer to run the service on (e.g. Raspberry Pi)
The bridge uses Python 3 and Pipenv for dependencies. To install, cd into the source tree and do pipenv install.
- Export list of sensors from the J-Link configuration software as XML file, e.g. into
jlink.xml. - Run
pipenv run ./jlink2sensors.py jlink.xml >jablotron.toml - Combine the resulting file with
jablotron.example.toml - Edit the created configuration file as appropriate to assign human-meaningful names to sensors or to comment-out unwanted sensors.
- Create a new user for HomeKit in J-Link and modify the
pinsetting in config accordingly. This is needed to change states; read only access doesn't require a PIN.
Run the service with pipenv run ./jablotron_server.py. See jablotron.example.service for an example systemd service.
