Accurately submeter your electrical consumption with the Smappee Plus or Pro
Monitor your gas and water usage and receive alerts of abnormal consumption or leaks with the Smappee Gas and Water Monitor
Control and submeter appliances and devices remotely with Smappee Plugs and Switches
Identify household appliances via Smappee’s patented NILM technology

NILM (Non-Intrusive Load Monitoring)

Here’s how it works…

You can compare Smappee to Shazam, the app that identifies songs. When an appliance uses electricity, it has an electrical ‘tune’- a unique tune for every appliance! Smappee uses its patented NILM technology to recognize the tunes of appliances. Then it assigns these tunes to the correct appliances and labels them as such.

Smappee named as CES Innovation Awards Honouree 2018

Amsterdam, 26th October 2017 Smappee, a leading developer of smart energy monitoring solutions, today announced that it has been named a CES 2018 Innovation Awards Honouree for its latest energy monitor and home energy traffic controller, Smappee Plus. Products taking part in this prestigious programme are judged by a team of industrial designers, independent engineers and members of the trade media to honour outstanding product design and cutting-edge engineering across 28 consumer product categories.

Smappee Plus measures real-time energy use from household appliances, offering valuable insights into a homeowner’s energy use and production. Smappee Plus is the only energy monitor that combines load disaggregation with submetering technology to provide real-time data also for appliances with variable output – such as air conditioning, electric vehicles, heatpumps, etc.-. Consumers are able to see how much energy a device uses and its daily, monthly or annual energy costs. Consequentially, owners can make informed decisions on their energy consumption (e.g. when to buy a more energy efficient fridge) and act to save on energy costs and efficiency.

Smappee Plus is also the only energy monitor that you can programme to take on the role of an “energy traffic controller” in the home. The product can automatically steer excess energy production, such as solar power, to appliances in order of preference, further increasing a homeowner’s energy efficiency and cost savings. You can choose from numerous “recipes” that automate certain actions, for example: when you are simultaneously charging your EV and starting to cook on an electric stove, Smappee Plus will control and diminish the power that goes to your car until you’ve finished cooking to avoid your fuses from blowing. Afterwards, the car will receive more power again. Because of this energy traffic controller function, Smappee Plus is also a tool that enables the future vision of turning homes into decentralised energy hubs that can produce, sell and buy renewable energy. The Smappee Plus is compatible with the Smappee Switch and various IoT platforms such as Amazon Alexa, IFTTT, Stringify and more, which allows the homeowner to automate activities or control appliances from a distance. It’s also the first energy monitoring system to be integrated with the cryptocurrency, SolarCoin.

“We are truly honoured to receive this recognition from the CES,”said Stefan Grosjean, CEO and founder of Smappee. “It’s the reward for the continuous hard work of our highly-driven team during the last 5 years. We will keep investing in our people and close partnerships in order to realise the vast potential of Smappee Plus, helping homes to become a true enabler of the decentralised smart energy grid and offer the best experience possible for any family.”

3 ways to submeter appliances.

Option 1: Submeter from the fusebox with Smappee’s clamps.

Submeter appliances right at the source: by attaching clamps to the distribution panel. The Smappee Plus energy monitor has up to 9 dedicated inputs for clamps. Depending on your electrical installation, you can measure 6 to 8 sub-circuits that consist of certain appliances or a group of appliances separately. It’s the perfect solution to gather the most accurate energy data down to appliance level and to know more about appliances with a variable capacity, such as a heat pump or an EV charger.

Smappee SubmeteringUsing the same technology, the Smappee Pro energy monitor for businesses keeps tabs on how much power certain appliances or appliance groups consume, across all company sites. Measure accurately and verify the impact of energy-saving measures to make changes wherever necessary.

Option 2: Submeter from the socket with Smappee Switch.

Submeter appliances by adding a submetering device. Supplement any of our Smappee energy monitors with a Smappee Switch, our genuinely intelligent smart plug. Besides remotely control appliances, the Smappee Switch has a submetering feature. Just connect the Switch between the socket and the appliance or a power strip. It accurately measures the energy consumption of the connected appliance or group of appliances separately (up to 16A) and shows it on the Smappee app and dashboard.

Option 3: Submeter from the power cable with our patented NILM.

By attaching a clamp to your power cable, Smappee energy monitors can use patented NILM (Non-Intrusive Load Monitoring) technology to detect appliances and their estimated consumption. This load disaggregation technology records the energy signal from a building and separates it into data that can be assigned to specific appliances. Find out here how this cost-efficient submeter option works and how users can improve Smappee’s NILM technology.

Thanks to the extensive range of submetering options, Smappee users can choose what options best fit their needs, depending on their electrical setup, the required level of accuracy and budget. Want to know more? Contact us at info@smappee.com.
