Best practice project - ongridVIShare Community https://www.viessmann.de/de/vishare-energy-community.html Thanks to gridX's IoT platform, the ViShare Energy Community Flatrate has been added to the Viessmann portfolio as an innovative and digital power product. The gridBox serves as a reliable communication gateway. With the ability to monitor and control the devices, prosumers can work together in an intelligent network to use energy more efficiently. With the gridBox as the brain of the network and an energy meter, customers meet all the requirements for the ViShare Energy Community. This combination allows optimized consumption of self-generated energy, without the need for expensive and process intensive smart meters or other measuring units. “The gridBox represents a complementing element for our E&H systems as well as central monitoring part for our ViShare Energy Community. I enjoy working with our product development partner as pragmatism, timeliness and thinking outside of the box, justified the choice of gridX.” Christian Harms-Ensink (Head of E&H System Solutions at Viessmann)
