Event types

Samples from different event types

Webhooks can be configured to send all available event types or specific ones. The configuration is made when adding or editing a webhook, either using the Dashboard or the API.

This page provides information about the different event types, example data, and what the data means.

All webhooks follow the same base structure:

{
	"id": "{Unique ID for the webhook}",
	"type": "{The event type for the webhook}",
	"source": "{URL to the webhook configuration in the Dashboard}",
	"dataContentType": "application/json",
	"labels": {},
	"data": [],
	"time": "{ISO 8601 timestamp}",
	"specVersion": "{Webhook specification version}"
}

The data object will contain the relevant information published by the event. For sample-events, there is a timestamp (recorded) included in the data object, and the delta between this and the timestamp on the webhook (time) will vary based on the relay device's (Space Hub's) connection to the cloud. If the Hub is connected to Ethernet, it will send data from connected devices to the cloud immediately when it is received, but if it uses cellular connection, it will buffer messages from connected devices and send them to the cloud every 5 minutes.

Hub Metadata Feed

The hub-meta-data-feed provides data from Airthings for Business Space Hubs whenever they send the data to the cloud. Hubs sends data to the cloud every hour if they are online, so these events can be used both to identify that the Hubs are connected to the cloud, and to get information about the devices connected to the Hubs.

Example data:

{

	],
	"time": "2023-07-05T13:09:43.673535",
	"specVersion": "0.2"
}

The lastSeenDevices array lists the serial number of nodes who has recently used the Hub as a relay device to send data to the Airthings cloud. The devices object provides a list of every device with the following information for each device:

FieldDescription
lastSeenEpoch timestamp for when the device last published data
rssiRSSI of SmartLink connection presented in dBm
typeType of device

The data also contains the type of connection (connectionType) the Hub uses to reach the cloud, which can be either cellular or ethernet.

Sample Feed

The sample-feed provides samples from the physical sensors in devices. The event is triggered whenever the device posts data to the cloud.

	],
	"time": "2023-07-06T07:19:36.632024",
	"specVersion": "0.2"
}

The data object includes the serial number of the device, a timestamp for when the sample was calculated, and the calculated number of occupants. It will contain 24 objects per device - two hours of data with a 5 minute interval - since the accuracy of the occupancy data improves over this two-hour period. This means that the most recent data will be the least accurate, and the least recent data will be the most accurate.

If information about the size of the room where the device is placed is entered in the Airthings for Business Dashboard, occupantsUpper and occupantsLower will be available in addition to a more accurate occupants value. The upper and lower values are an estimation of the accuracy from the occupancy calculation, and represents the potential lowest and highest amount of occupants detected in the room.

The sensorUnits object provides information about the measurement unit the sensor value is presented in.

Ventilation Rate Feed

The ventilation-sample-feed provides samples from the ventilation rate virtual sensor. The event is triggered whenever the virtual sensor is calculated.
