CO2 Signal Instructions on how to use CO2Signal data within Home Assistant

The co2signal sensor platform queries the CO2Signal API for the CO2 intensity of a specific region. Data can be collected for your home, a specific latitude/longitude or by country code. This API uses the same data as https://www.electricitymap.org. Not all countries/regions in the world are supported so please consult this website to check local availability.

Prerequisites

To configure and use this integration, you need to obtain a free API key from CO2Signal.

{% include integrations/config_flow.md %}

Sensor Types

When configured, the platform will create two sensors for each configured location: the carbon intensity expressed in gCO2eq/kWh and a percentage how much the grid relies on fossil fuels for production.
