As energy consumption rises across the globe, we should not only be concerned with coming
up with new and improved ways of generating and storing energy, but we should also have a
good look at how we currently consume energy.
EcoMonitor is a neat little device that plugs directly into the HAN –port on the new (AMS)
electricity meters being phased in, in Scandinavia and other European countries. The
EcoMonitor paired with a cloud solution for data processing gives the user a unique insight
in the total electricity usage throughout the day and week – with a resolution down to
seconds. This enables greater insight and a way of understanding power usage for the
The goal and aim for the system developed by hark technologies is not only to be a way of
gathering and presenting data about power usage but to also to use this data and automate
our homes and this way ultimately save electricity – True power optimization enabled by

EcoMonitor has already identified costly errors in the setup of consumption control systems
in both private and commercial buildings, as well as errors in electrical wiring and
installations. With EcoMonitor electrical systems can be optimized, errors can be both
discovered and prevented, and our understanding of electricity usage broadened.
