The nearest national station isn't your network

Many heating networks sit far from the nearest official weather station and a few degrees of difference at the wrong momentmeans over-production, wrong flow temperatures, or an unnecessary peak-boiler start. A Cordulus station at your plant measures the temperature your network actually experiences.

Hyperlocal temperature measurement at plant or network.

Close the gap between official forecasts and local reality.

Affordable subscription - hardware, maintenance and data included.

Feed your planning with local ground truth

Cordulus delivers measured local temperature and AI-enhanced short-term forecasts via API - directly into the demand forecasting and production planning tools you already use.

API feed of measured local conditions and forecasts.

Works alongside your existing forecasting and optimisation tools.

Local forecast correction that improves as the station learns your site.

Put local weather straight into your planning systems

Your demand forecast, production plan and optimisation tools are only as good as the data they're fed. The Cordulus weather API delivers measured local temperature, AI-enhanced short-term forecasts and historical data from your station directly into the systems you already run. No manual exports, no copying numbers from a weather site.

Cordulus API with real-time, forecast and historical data.

Feeds demand forecasting, production planning and control systems directly.

One integration, every station in your network.

One data feed for your whole network

District heating networks rarely sit in one place. Plants, pumping stations and supply areas can be spread across many kilometres, and so can the weather. With Cordulus you choose how many stations your network needs, and all their data comes together in one place: measured conditions, short-term forecasts and history for every location. It's available through the API or delivered in another format on request.

Choose the number of stations that fits your network.

All stations' data accessible through our API.
