Carlo Gavazzi VMU-C EM Gateway

Are you ready for energy savings? Enable our cloud-based energy analytics and dashboard for your Carlo Gavazzi VMU-C EM Gateway , to discover, measure and verify savings in the premises you manage. The VMU-C EM is a device used to collect data from a network of energy meters and environmental sensors; its FTP push function enables that data to be periodically transmitted to Wattics for advanced analysis.


It is assumed that your VMU-C EM Gateway already collects data from your meter(s). If not, read and understand Carlo Gavazzi manuals for installing, operating, or maintaining your VMU-C EM Gateway. Installation and program procedures must be carried out and inspected by qualified personnel. Qualified personnel are those who, based on their training and experience, are capable of identifying risks and avoiding potential hazards when working with this product.
