System integrators
Add a measurement history to existing installations. We assess the data source, interface and connection to the cosy-hub with you.
Inside the real application
This is cosy-sense in use.
Original screenshots from the CoSy-Tec demo installation in cosy-connect, captured on 30 October 2026. These are snapshots of the German interface. Open an image to enlarge it.

The demo installation shows two connected sensors. Additional received values are listed for assignment to sensors.

The original configuration dialog: assign a device and field, set the measurement unit and define thresholds for control rules.
For companies, developers and integrators
Capture with cosy-sense. Store with cosy-data.
A live value tells you what is happening now. A history helps you understand how your equipment behaves over time. Use cosy-data as the measurement data store in your integration project, with cosy-sense where sensor connections are needed.
Capture
cosy-sense / REST
Readings from sensors, gateways or your own system.
Store
cosy-data
Record numeric values with timestamps locally on the cosy-hub.
Use
cosy-connect
View history in your browser and export readings as CSV.
cosy-data runs on the cosy-hub. cosy-sense is in beta; we clarify suitable devices and the integration scope before implementation.
Device and equipment developers
Your device supplies the readings. cosy-data provides local recording, while cosy-connect provides history and CSV export.
Building and energy technology
Compare temperature, CO₂ or energy readings over time. The usable measurements depend on the connected sensors and meters.
Discuss your integration
Need a data store in your system?
Tell us which devices supply the readings, how often they arrive and how long you need to retain them. We assess the connection, storage and evaluation together. Pricing and scope are defined in an individual quote.
Questions about storing and connecting data
Can I connect my existing system?
cosy-data accepts numeric readings via a local REST interface. We check the data format, sensor assignment, access protection and any adapter needed for your system as part of the project.
Do I always need cosy-sense?
No. Systems that already supply suitable readings can send them directly to cosy-data via REST. cosy-sense adds sensor polling and the reception of readings from devices and gateways.
Where are the readings stored?
Recording takes place locally on the cosy-hub. cosy-connect receives the readings for central browser access, history and CSV export. Remote access requires a connection to cosy-connect.
How long can I keep the data?
Storage medium, measurement interval and number of sensors determine the volume of data. We define the required retention and storage capacity for your project; we do not promise unlimited archiving.
