Smappee analyses the use of solar energy, gas, water and electricity down to circuit and appliance level. Users get energy insights and discover their energy consumption, production, energy guzzlers, standby power, etc. in real-time, anytime and anywhere using the Smappee App and Dashboard.

The Smappee Switch, Scenes and partnerships with third-party IoT solutions empower users to steer energy automatically to appliances in the order of their preference, store it in the battery or switch appliances on or off in the most energy-efficient way, optimising auto-consumption and enabling self-sufficiency.

Smappee aims to change its users’ energy habits by reducing their energy consumption without compromising on comfort. This ensures that both the user and the environment benefit from Smappee’s energy efficiency solutions.

An energy monitoring system will allow you to cut ever-rising energy costs and facilitate auto-consumption, using the renewable energy produced to its fullest. To do that, you need real-time, actionable energy insights and the ability to automate the energy flows on your premises. Appliances need to switch on or off automatically when production peaks or is at a low and surplus energy needs to be stored for later. Smappee allows just that, paving the way for a future in which buildings are decentralized energy hubs without having to compromise on comfort.

Smappee is the only energy monitoring system that gives you insights at a glance into electricity, solar production, gas and water. Smappee Infinity also offers the most comprehensive submetering facilities in the market with three submetering options: using current clamps, the smart plug Smappee Switch or Smappee’s patented NILM (Non-Intrusive Load Monitoring). Thanks to its submetering capabilities, real-time energy data and ability to set scenes, Smappee can also take on the role of an Energy Traffic Controller. In other words, Smappee is capable of automatically steering energy to appliances in the order of your preference, storing it in the battery or switching appliances on or off in the most energy-efficient way. As such, Smappee Infinity optimises auto-consumption and enables self-sufficiency.

Smart meters only visualise the total energy consumption from the installation’s grid and energy supplied to the grid on a regular basis. The smart meter does not provide any information about:

  • real-time energy use and the impact of your actions on that
  • which circuits or appliances make up the total consumption value
  • exactly how much energy a circuit or appliances uses and when
  • your total solar production and how much of it you consume yourself
  • gas and water consumption data

Smappee Infinity provides submetering and load disaggregation capabilities to visualise real-time consumption up to circuit and appliance level, the total solar production and the status of battery storage. This gives insights in the energy flows within your building. Smappee also takes on the role of an Energy Traffic Controller. This means that Smappee is capable of automatically steering energy to appliances in the order of your preference, storing it in the battery or switching appliances on or off in the most energy-efficient way. As such, Smappee Infinity optimises auto-consumption and enables self-sufficiency.

The Smappee Infinity has three essential components:

  1. Smappee CT Hubs: are the main components of the monitoring system. You can connect up to 4 CTs or Rogowski coils to the CT Hub to measure different currents, ranging from 50A to 1000A. This allows for accurate submetering of an appliance or group of appliances. Use a daisy chain of up to 7 CT Hubs to measure different installations over a distance of up to 100 meters.
  2. Smappee Power Box: this is the heart of the monitoring system as it provides power to all components. It measures the line voltage of the different connected phases and transfers the data via the Smappee Bus.
  3. Smappee Genius: is the gateway between the monitoring system and the Smappee Cloud, ensuring secure data storage from different components. It also interacts with third-party components, Smappee Gas & Water and Smappee Switch. A typical Smappee Infinity set-up consists of 1 Power Box, 1 Genius, several CT Hubs and several CTs. 


Thanks to the Energy Traffic Control functionalities, Smappee Infinity is capable of automatically steering energy to appliances in the order of your preference, storing it in the battery or switching appliances on or off in the most energy-efficient way. As such, Smappee Infinity optimises auto-consumption and enables self-sufficiency. 

There are multiple ways to detect your appliances with Smappee:

  • Connecting current transformers (CT) in your fuse box (provides real-time 1 second information)
  • Connecting a Smappee Switch between the power outlet and the appliance for wireless submetering of mono-phase appliances (provides data at 5-minute intervals)
  • Submetering with Smappee’s patented NILM (Non-Intrusive Load Monitoring). Smappee NILM provides insight into appliance consumption (70% of consumption and events in the appliances detected) and monthly consumption per identified appliance. On average, 4 to 5 main household appliances are identified after a few weeks. This function is disabled by default and for residential use only.

Installation is done in two parts: physical installation in the fuse box and configuration using the step-by-step installation wizard in the Smappee App or Dashboard. The compact plug-and-play system is robust and reliable, with hubs connecting current clamps (CTs). Thanks to its modularity, additional single- or three-phased energy metering can be installed in five to ten minutes. Maintenance requires little effort, which keeps the total cost of ownership low.

Get a Smappee Switch for operating appliances remotely and for wireless submetering of mono-phase appliances.

Smappee Switch works with the most popular plugs (B, E, F, G, I, J, L, M) and can switch to capacities of up to 16A (country-specific). Smappee Switch works on the 433 MHz or 915 MHz (US) frequency and must therefore be located within a maximum range of 10 to 20 metres of your Smappee monitor. Dynamic switching (e.g. reducing water heater from 16A to 8A at peak times) is only possible for smart appliances and only when combined with the Energy Traffic Controller, which is supplied with Smappee Infinity. Switch’s switching functionality is thus limited to an on/off function.

You want to use multiple Smappee Switches? You can configure up to 20 Smappee Switches using one Smappee energy monitor. You can also use your Smappee Switches in your cellar, attic or other rooms in your house where nromally you cannot receive any communication signal. A Switch can pass on the signal to another Switch so you can bridge longer distances and overcome obstacles such as concrete. You can link up to 3 Switch stations and the maximum range between each of these stations is 10 to 20 metres.

!Important! Smappee Switch only works with a Smappee energy monitor.

The Smappee Gas & Water takes the readings from your gas and water meters, using an optical or magnetic sensor, and sends this data to the Smappee App and Smappee Dashboard. Unfortunately, the gas and water monitor does not work with digital meters, gas meters with magnetic output or meters with red revolving dials.

The Smappee Gas & Water needs to be installed within 10 to 20 metres of your Smappee energy monitor. It is also important to have a smartphone or tablet running at least Bluetooth 4.0 LE.

You can use the Smappee Gas & Water in your apartment. If the meter is installed in the basement, you will need Bluetooth for data transfer to your smartphone or tablet. In this case, you will need to go regularly to your gas and water monitor (within 7 metres), open the Smappee App and wait for 20 seconds. The Smappee Gas & Water and the App will automatically find each other and exchange data. We suggest you do this once a month.
