HomeBridge module for the DIY luftdaten.info air particulates sensor from OpenData Stuttgart.
It can be used to see the status of your own sensor in HomeKit. You can also use it to see another sensor if it's data is published to api.luftdaten.info (see here).
First follow the instructions for HomeBridge.
Install homebridge-airrohr
using (sudo) npm install -g homebridge-airrohr
.
Configure your AirRohr sensor in the homebridge
settings file. See conig.sample.json. All settings except update_interval_seconds
are required (defaults to 120 seconds).
To run this project you have two options
To do this set json_data
to
http://feinstaubsensor-<YOUR_SENSOR_ID>.local/data.json
using the same local network as your sensor.
Note: If you use a HomeKit hub (like a Apple TV or a iPad) you can still access your data from outside your home. See Apple's documentation for details.
Don't set public_temperature_json_data
or public_airquality_json_data
in this scenario.
This allows you to add any sensor not only your own. To get the same functionality as above you need to set two IDs/URLs:
-
Set
public_temperature_json_data
to the URL where to find the temperature data:http://api.luftdaten.info/v1/sensor/<YOUR_TEMPERATURE_SENSOR_ID>/
-
Set
public_airquality_json_data
to the URL where to find the air particulates (PM10, PM25) data:http://api.luftdaten.info/v1/sensor/<YOUR_AIRQUALITY_SENSOR_ID>/
Don't set json_data
in this scenario.
Note: If you set json_data
the public_…
settings will be ignored.
