Our Data Hub

Our Data Hub is a secured Cloud-based platform that allows energy and environmental actors to centralise, enhance, analyse, and visualize their data.

Because our Data Hub is designed specifically for energy and environmental actors, it includes built-in industry-standard rules, capabilities, and analytics, which enable our clients to exploit their data more precisely, quickly, and securely.

Our offers

Opinum Data Hub is built to collect data from various sources, from metering information to contextual data sets (weather, building usage, energy prices, etc.) and to make sure data is qualitative.


No matter the technologies, Opinum Data Hub can connect to your data

Opinum Data Hub exposes a set of features to easily import your data from external data sources to IoT devices. Our product exposes an Open Rest-ful API to push data in any format. An ETL process makes it possible to standardize the data. 

On top of our standard API, Opinum partners with equipment manufacturers, open data standards and application builder to process a set of useful, pre-built connectors such as Smappee, EWattch, Siemens, ...


Customize the data model to your needs and build a global relation between your sources of data.

Opinum Data Hub allows you to structure information. Customize the structure of timeseries data and meta-data into meaningful sources of information and define the relation between the sources using our Graph structure.

The platform features a bulk provisionning system, Master Data, allowing you to create/update and configure massive deployment of objects.


Always full data

Data Quality is the core concept of good analytics. Opinum Data Hub constantly browses your data to check for any data gaps or/and outliers that could point out issues in the data collection process. Through advanced filtering options, user can visualize data quality issues and apply existing or custom algorithms to reshape the data, and make them available and usable in further processing steps.

All data sets are versioned to make sure you can restore data in case of wrong reconstruction.


Process data thanks to calculations

Through calculated variables, user can inject complex machine learning algorithm written in R or Python into the platform. Opinum Data Hub executes these algorithms, maintains and stores the output results in new variables accessible for further interpretation in the analytics module.

Input for these algorithms can be set as other variables, properties (meta-data), or constant values.
