Aether

Aether is an air quality monitoring device and software, Open Source and powered by .NET 6.

Want to make your own? Check out the no-soldering-required Hackathon 2021 build, pictured to the right.

Features

At-a-glance air quality monitoring with addressable RGB.
Small standalone device with a custom 3D-printed case.
No-solder plug-and-play hardware.

Planned

SD image for easy deployment.
Monitor air quality over a Web Bluetooth enabled website.
Monitor air quality over Bluetooth/WiFi via a .NET MAUI app.
(Optionally) Join a WiFi network for multi-room monitoring.
(Maybe) MQTT support.
(Maybe) Zigbee / LoRa / LoRaWAN support.

Contributing

Contributions are welcome. Please contact me with any questions. The desired workflow is:

File an issue describing the bug or desired enhancement.
If you intend to perform the work on an issue, ask for it to be assigned to you.
If the issue is for an enhancement, wait for it to be approved.
File a PR. Make sure to link the issue it will close in the top comment.

Aether could use contributions for:

Web and mobile dev, for Bluetooth apps.
Linux deployment (install instructions and/or SD image creation)
Linux Bluetooth (need to make the Aether into a BLE device)
Driver dev (C#).
General .NET dev (C#).
3D modeling for case design.
