Gira is a german manufacturer of house appliances, including door systems. These systems are connected via a proprietary two wire bus system. GDOOR is a project to collect and document findings about the Gira Door System, all figured out by reverse engineering.
The GDOOR hardware adapter allows listening and controlling the bus and e.g. integrating a Gira door bell into a smart home. It might serve as an DIY alternative to the Gira TKS-IP-Gateway. It supports the following features:
- listening to the bus, e.g. to trigger notifications on mobile devices when a door bell button is pressed
- sending to the bus, e.g. to open the door
Receiving and sending audio/video is currently neither supported nor plannend.
Contributions are welcome!
Currently work is ongoing to release a ESP32-based adapter, which translates the bus messages to MQTT/serial and vice versa.
Hardware can be found in the hardware subfolder,
corresponding firmware in the firmware subfolder.
Note
Work is not finished yet.
