This is a prototype Rust version of the super hacky homer_node NodeJS project. It's primarily intended to teach me Rust, and also learn about how it can be practically used in a real embedded / IoT systems.

The project is intended to run on devices like Raspberry PI and ...

Read from:

• 1-write sensors
• Bluetooth LE sensors, currently using btleplug

Publish to:

• MQTT, supporting Home Assistant MQTT Discovery
• AWS CloudWatch

Home automation tasks such as:

• Automatically Open velux window when bathroom is hot and humid
• Trigger a CloudWatch alarm when fish tank is too cold

The code as is will only compile on Windows due to some issues with the Bluetooth driver abstraction layer. This will be resolved when I understand Rust better.

Pi 1-Wire support is missing. It should trivial as it's just presented as a filesystem.

Dependencies are a bit of a mess with both MQTT driver Bluetooth requiring a worker thread in addition to Tokio dependenices. It looks like the Tokio archiecture could scale to microcontrollers but it's not there yet.

• Make bluetooth stack portable compile on PI and Mac.
• Actually implement 1-Wire on PI
• Minimize dependencies
• Understand libraries, dynamic loading and ABI's
