This project was created for educational purposes. And was never intended for use in any production setting. To prevent forks and attempts to contribute I have archived it.
The purpose of this project was to explore Mobile Applications, Embedded devices, And Decentralized Networking.
Smart homes today mainly rely on wifi for commutation. This is not a scabble solution. Wifi access points are not made to connect with 100+ devices at once. Mesh networks which pass message from device to device can support thousands of devices which is more suitable for smart homes.
This project is a smart home system that makes use of mesh networks enable better scalability.
The project consists of several components that work together to form a complete solution.
- HomeApp: Enables users to setup, configure, and control the smart home.
- HomeNodes: Nodes (Steps in a drag and drop script) that can be used with Node Red for automation.
- HomeHub: Central local device. Stores smart home data (groups and scenes). Connects bluetooth mesh network to the mobile app and node red. Provides a graphql api
- MeshController: Coprocessor device connected over usb. Provides bluetooth mesh connectivity to host device.
- GoMeshController: Golang Library for using the MeshController Coprocessor.
- ButtonFirmware: A sample device in the mesh network.
Mobile App/Node Red <==> Home Hub <==> Coprocessor <==> Mesh Devices
A nrf52840 dev kit and a nrf52832 dev kit are required for this.
Clone this repo and all its submodules and open the workspace in vscode.
Under /tools the script setup.sh will download all the needed tooling (on ubuntu).
To flash the firmware for the Button and MeshController run /tools/upload_fm.sh SN1 SN2.
The dockerfile in /HomeHub is used for deployment for the hub.
The dockerfile in /HomeNodes deploys a instance of node red with HomeNodes included.
The HomeApp can be installed on a phone though the flutter extension in vscode.
