Weather Data

Conserv customers consistently tell us that access to weather data in their analytics is important to them.  Showing weather and location sensor data on the same graph can help you understand how effective your building and systems are at controlling the indoor environment.  So, where does the data come from?

Open-Meteo

As of 2026, Conserv Cloud Analytics uses Open-Meteo - an open-source weather API. The following information has been taken from their website (retrieved Jan 9, 2026):

Open-Meteo brings together cutting-edge local (1 km resolution) and global (11 km) weather models sourced from renowned national weather services. This means you have access to the most accurate forecast for any location worldwide. National weather services include Deutscher Wetter Dienst (DWD), National Oceanic and Atmospheric Administration (NOAA), Meteofrance and Canadian Meteorological Center (CMC).

Open-Meteo APIs are designed to provide you with the most precise weather information for your location. We select the highest resolution weather models available, ensuring detailed forecasts for your specific area. If you're in Europe or the US, we utilise impressive 1-2 km high resolution models for even greater accuracy.

Our APIs deliver hourly weather data for a 7-day forecast. The first 2-3 days of the forecast are calculated using high resolution models, offering you detailed predictions. After that, global weather models take over. This seamless integration results in a simple and reliable hourly forecast for the week ahead.

At Open-Meteo, we understand the importance of up-to-date weather information. That's why our local 1 km resolution models are updated every hour, ensuring that our forecasts are always current and accurate.

To provide you with reliable predictions, our weather models incorporate real-time measurements, airplane data, buoys, rain radar, and satellite observations. These sources of information contribute to the precision of our numerical weather forecasts, giving you the most reliable data for your location.

How we set the location

If you have set an address in your Location in the Hierarchy, we use that. If not, we use the address in your Organization Settings. Make sure your address has been set accurately.

We process the address through Google Maps Geocoding to get latitude and longitude coordinates.

The coordinates are used in Open Meteo to get the historical or forecast data for the closest possible place to those coordinates. This means we are not just pulling data from a weather station that may have a completely different climate from your location.
