The deZem system
Whether you need the development of a new measurement infrastructure, the integration of existing systems or the merging of IoT data from various sources on a centralised data platform: deZem offers a solution tailored to your requirements.
The modular IoT analytics software, the deZem DataSuite, also offers a wide range of options for visualisation, analysis and reporting - user-friendly and highly reliable. It enables users to identify energy-saving potential, increase efficiency and productivity, reduce costs, and conserve resources.
Data collection, data management on the central platform, and the DataSuite software together constitute an integrated system, yet they can also be used very effectively as standalone solutions.
