DEPRECATION
This plugin is now deprecated/archived/read-only.
It is recommended that you switch to the second generation Homebridge Dynamic Platform plugin: homebridge-awair2
homebridge-awair
Awair plugin for homebridge: https://github.com/nfarina/homebridge
Based on the great work of @henrypoydar.
This is a very basic plugin for Nfarina's amazing Homebridge project. It will fetch current sensor conditions from an Awair device (e.g. Awair, Awair Glow, Awair Mint, Awair Omni, Awair 2nd Edition or Awair Element) and provide available sensor readings (e.g. temperature, humidity, carbon dioxide, TVOC, and dust/PM2.5/PM10) information for HomeKit.
You can look at the current Awair information via HomeKit enabled Apps on your iOS device or even ask Siri for them.
It will get new data once every 15 minutes (default), but it can be customized in config.json.
Installation
-
Install homebridge using:
[sudo] npm install -g homebridge -
Install this plugin using:
[sudo] npm install -g homebridge-awair - Update your configuration file. See the sample below.
You'll need to run an HTTP request to obtain each Awair's device ID (devId) and device type (devType).
curl -X GET \
http://developer-apis.awair.is/v1/users/self/devices \
-H 'Authorization: Bearer {developer-token}'
You'll also need to request access to the Awair Developer Console to obtain your Developer Token (token).
The Awair Developer API Documentation explains the inner workings of the Awair Developer API, but for the most part is not necessary to use this plugin.
Configuration
Configuration sample:
Add the following information to your config file (note: shown with (6) example devices: Awair, Awair Glow, Awair Mint, Awair Omni, Awair 2nd Edition and Awair Element).
