-The `co2signal` sensor platform queries the [CO2Signal](https://www.co2signal.com/) API for the CO2 intensity of a specific region. Data can be collected via 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.
-
-This platform requires a CO2Signal API key, which can be obtained [here](https://www.co2signal.com/). Note that this API key is for personal use only and other options exist when the data is used commercially.
-
-At the moment, the free CO2Signal API only supports the average carbon intensity of a country and not the marginal carbon intensity.

-<div class='note warning'>
-The "free" API key is limited to a limited number of calls. Too many requests can result in data loss.

 ## Sensor Types
 
-When configured, the platform will create one sensor for each configured location.
+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.
