Businesses and institutions of all sizes are trying to reduce their energy consumption and bills: to do this, they need to understand in details how their buildings operate and how to control their consumptions.

Seven years of research, backed up by real-life deployments at client sites, led to the development of Wattseeker technology – a turnkey system that is effective and reliable and based on highly sophisticated algorithms.

Wattseeker is a radical innovation. It is made of a unique metering system linked to intelligent sensors, allowing a multi-fluid cartography itemised by areas, usages and appliances.

Our metering system is fast & easy to deploy and non-intrusive, allowing a turnkey service of high quality. Prices are very competitive, guaranteeing a return on investment time qhorter than one year.

Installed at the electricity mains panelboard, it assesses energy consumption in real time (Qualified Metering Service) and provides an accurate analysis itemised by areas, appliance, and usages (Augmented Metering Service), along with advice delivered by energy experts in Qualisteo team (Interpreted Metering Service).


NIALM stands for “Non Intrusive Appliance Load Monitoring”.

NILM (Non Intrusive Load Monitoring) is occasionally used as a synonym for NIALM.

NIALM designates any method of monitoring the individual electricity consumption of several appliances without using a separate meter for each appliance. In practical terms, a NIALM system consists in one or several physical metering points (generally non-intrusive) that provide a load curve for an entire building or for specific areas within a building (floors, workshops, etc…), coupled with software that processes the physical readings taken at the said points.

The NIALM system then uses advanced signal processing algorithms to break the load curves down into individual consumptions for each recognised appliance. This gives a load curve for each recognised appliance or group of appliances, “as if” a meter had been used to monitor them.

The Wattseeker solution uses very sophisticated algorithms that are the fruit of many years of research and development. They rely on specific pieces of information to distinguish several classes of equipment (resistances, lighting, engines, micro-waves ovens, ventilation, computers, etc.) and various complementary differentiation factors (active power, power factor, single-phase, three-phase, automated, operating cycles, etc…).

The algorithms can be applied to various levels of the electrical system. When applied to the mains of the overall system, they recognise the main appliances wherever they are located within the building. When applied to the low voltage general distribution board at the general board and to the feeding lines to various areas (or floors), they offer a more detailed analysis including a breakdown into areas, appliances and usages.


The disaggregation rendered possible by our NIALM system offers the same advantages as a complex sub-metering solution deployed throughout the entire building, which would be much more complex costly, and longer to install.
