Energy Guide

This guide provides insights into retrieving and analyzing energy, gas, and water consumption data using the Wia API. You will learn how to configure the flow of data (consumption vs. production), filter data by device properties, and handle timestamps effectively.

Step 1: Get Your API Key

  1. Create your account and log in.
  2. Navigate to your dashboard to retrieve your API key or, depending on your representative, you may have been sent a key.
  3. If you don't have an API key, please contact your representative.

Your API key is required to authenticate all API requests.

Step 2: Retrieve Energy Data

The Wia API allows you to retrieve energy, gas, and water consumption data. These data points can be grouped by devices, spaces, or countries.

Example Request for Electricity Consumption

curl -X GET "https://api.wia.io/v1/energy/electricity?space.id=spc_abc123&since=1704067200000&until=1704153600000&flow=consumption" \
-H "Authorization: Bearer YOUR_API_KEY"
  • space.id: Specify the space for which you want data.
  • since: Start of the time range timestamp.
  • until: End of the time range timestamp.
  • flow: Set to consumption for energy used or production for energy generated.

Response Example

{
  "result": [
    {
      "energy": "1000",
      "timestamp": 1631707200000
    },
    {
      "energy": "1200",
      "timestamp": 1631710800000
    }
  ],
  "continuationToken": null
}

Step 3: Retrieve Gas and Water Data

The process is similar for gas and water data.

Example Request for Gas Consumption

curl -X GET "https://api.wia.io/v1/energy/gas?space.id=spc_abc123&since=1704067200000&until=1704153600000&flow=consumption" \
-H "Authorization: Bearer YOUR_API_KEY"

Example Request for Water Consumption

curl -X GET "https://api.wia.io/v1/energy/water?space.id=spc_abc123&since=1704067200000&until=1704153600000&flow=consumption" \
-H "Authorization: Bearer YOUR_API_KEY"

Step 4: Group Data by Devices or Countries

You can group data by devices or countries for more granular analysis.

Example Request for Device-level Breakdown

curl -X GET "https://api.wia.io/v1/energy/electricity?space.id=spc_abc123&since=1704067200000&until=1704153600000&breakdown=device" \
-H "Authorization: Bearer YOUR_API_KEY"

Response Example

{
  "devices": {
    "dev_abc123": [
      {
        "energy": "1000",
        "timestamp": 1631707200000
      }
    ],
    "dev_def456": [
      {
        "energy": "1200",
        "timestamp": 1631707200000
      }
    ]
  }
}

Example Request for Country-level Breakdown

curl -X GET "https://api.wia.io/v1/energy/electricity?since=1704067200000&until=1704153600000&breakdown=country" \
-H "Authorization: Bearer YOUR_API_KEY"

Response Example

{
  "countries": {
    "IRL": [
      {
        "energy": "2000",
        "timestamp": 1631707200000
      }
    ],
    "DEU": [
      {
        "energy": "1500",
        "timestamp": 1631707200000
      }
    ]
  }
}

Step 5: Handling Timestamps

All timestamps in the API are in UTC. Use the timezone parameter to adjust data for your local timezone.

Example Request with Timezone

curl -X GET "https://api.wia.io/v1/energy/electricity?space.id=spc_abc123&since=1704067200000&until=1704153600000&timezone=Europe/London" \
-H "Authorization: Bearer YOUR_API_KEY"

Interval Aggregation

You can specify the data aggregation interval using the interval parameter (e.g., 15 minutes, 1 hour, 1 day).

Example Request with Interval

curl -X GET "https://api.wia.io/v1/energy/electricity?space.id=spc_abc123&since=1704067200000&until=1704153600000&interval=1 hour" \
-H "Authorization: Bearer YOUR_API_KEY"

Summary

The Wia API provides robust options to retrieve and analyze energy, gas, and water consumption data. You can:

  • Choose between consumption or production flow.
  • Group data by device or country.
  • Handle timestamps effectively with timezone and interval parameters.

Use these features to monitor usage trends, optimize energy management, and make data-driven decisions.
