# homebridge-awair2
[](https://github.com/homebridge/homebridge/wiki/Verified-Plugins)  
This is a second generation Homebridge Dynamic Platform plugin for the Awair family of air quality monitors implemented in TypeScript for Nfarina's [Homebridge project](https://github.com/nfarina/homebridge). The Awair2 plugin is based on the [homebridge-awair](https://github.com/deanlyoung/homebridge-awair#readme) plugin developed by Dean L. Young.
---
NOTES:
`v5.11.x` Incorporates updated Awair Score methodology for Awair Element (Firmware v1.4.0) and Awair Omni (Firmware v1.8.0) introduced by Awair in Dec 2023. See [Reference](https://support.getawair.com/hc/en-us/articles/19504367520023#h_01HE1QVJ85K55N7QS8NAVBXWJM).
The IAQ Score System integrates readings from five sensors: Temperature, Humidity, Volatile Organic Compounds (VOC), Carbon Dioxide (CO2), and Particulate Matter (PM2.5). In the previous system, each factor contributed equally (approximately 20%) to the total score. The new air quality scoring system begins with normalizing sensor data to a scale where 0 represents good quality and 1 indicates the worst, assigning values that correspond to a range of scores. The final Indoor Air Quality (IAQ) score is a composite of the highest normalized values from CO2, VOC, and PM2.5 readings.
The new Awair Score level is displayed in Homebridge on the Accessory tile for Awair Element and Awair Omni in addition to the Homekit level. Awair r2 only displays the Homekit level. Unfortunately, HomeKit levels are defined by the HomeKit API and cannot be customized.
Score | new Awair level | HomeKit level
:-: | :----: | :---:
1 | GOOD | EXCELLENT
2 | ACCEPTABLE | GOOD
3 | MODERATE | FAIR
4 | POOR | INFERIOR
5 | HAZADAROUS | POOR
iOS Awair app version 4.7.3 is required to view the updated scores.
`v5.10.x` removes support for Awair v1 (including Awair Baby), Awair Glow, and Awair Glow-C. These devices have been "sunsetted" by Awair as of 30 November 2022. These devices are no longer supported by the Awair iOS app or the Awair Cloud which the plugin relies on. Additional details can be found [here](https://support.getawair.com/hc/en-us/articles/9948422782999-How-to-identify-device-models-and-features-that-will-close-by-Nov-30-2022).
`v5.9.x` introduced binary limit switches for VOC and PM2.5. The switches are implemented as dummy `occupancy sensors` and can be used to trigger HomeKit automations.
`v5.7.x` introduced control of the Awair device display for Awair Omni, Awair r2, and Awair Element. Reference Wiki for details and examples of HomeKit automations for this feature.
---
The Awair2 plugin will query your Awair account using a Developer Token to determine registered Awair devices which were setup through the Awair iOS app. While running, the plugin will fetch current sensor conditions for each Awair device (e.g. Awair Mint, Awair Omni, Awair 2nd Edition, or Awair Element) and provide sensor status and value (e.g. temperature, humidity, carbon dioxide, TVOC, PM2.5, Omni lux, and Omni battery) to HomeKit. You can look at the current Awair information via HomeKit enabled Apps on your iOS device or even ask Siri for them.
The plugin will fetch new data based on selected `endpoint` and User Account tier. For 'Hobbyist' tier, `15-min-avg` endpoint samples every 15 minutes, `5-min-avg` every 5 minutes, `latest` every 5 minutes and `raw` every 3.3 minutes (200 seconds). The main difference between the `latest` and `raw` endpoints is that you can define a `limit` (i.e. number of consecutive data points) for the `raw` endpoint, in order to create your own averaging (e.g. `.../raw?limit=12` for a 2 minute average.
With iOS16, the layout, icons and status were refined in the iOS/iPadOS/macOS Home apps. Temperature and humidity are grouped under a single "climate" status icon at the top of the HomeKit screen. If you select this icon a screen opens with all of the Climate devices in your HomeKit.
For those with multiple Awair devices, you can optionally list the macAddress of the device (found on the back or bottom of the device) which you want to exclude from HomeKit.
For Awair Omni, battery charge level, charging status, low battery, light level and occupancy detection based on ambient sound level [experimental] are also provided using the Local Sensors capability which is configured in the Awair App.
Battery Status does not appear as a separate tile in the HomeKit interface. Battery charge level and status will be found in the Status menu for each of the sensors. A low battery indication will be identified as an alert in the HomeKit status section.
---
NOTE:
If you are setting up an Awair unit for the first time, it is recommended that you allow a couple of hours after adding to the iOS Awair App for the unit to calibrate, update firmware if necessary and establish connection to the Awair Cloud. Initially the accessories may show up in Homebridge and HomeKit, however, the data field may be blank. This will correct after the data stream has been established between your Awair device and the Awair Cloud.

# Installation
1. Install homebridge, reference [Homebridge Wiki](https://github.com/homebridge/homebridge/wiki)
2. The easiest way to install the Awair2 plugin is through the `homebridge` interface. Select `Plugins` at the top menu bar, search for `Awair2` and then select install. Alternately, the plugin may be installed from the command line using: `[sudo] npm install -g homebridge-awair2`.
3. Update your configuration file. See the sample below.
The Awair2 plugin queries your Awair account to determine devices that you have registered. This is the same informaton that you have entered via the Awair app on your iOS device.
You will need to request access to the [Awair Developer Console](https://developer.getawair.com) to obtain your Developer Token (`token`). You can also request your Developer Token directly through the Awair App on your iPhone. From the App, select 'Awair+' in the lower right hand corner, then select 'Awair APIs', select 'Cloud API' and finally 'Get API Token'.
The [Awair Developer API Documentation](https://docs.developer.getawair.com) explains the inner workings of the Awair Developer API, but for the most part is not necessary to use this plugin.
