How does Smappee Pro for businesses work?

Smappee monitors measure energy use in real time using the patented Smappee NILM (Non-Intrusive Load Monitoring) technology. Smappee Pro can also be used for submetering through the additional inputs, to which additional clamps can be attached. These additional inputs can individually measure and display subcircuits in the Smappee app or online at Submetering allows you to detect and monitor appliances with complex consumption patterns, such as those with a variable output (heat pumps and air conditioning units).

Smappee Pro comes with a Pro licence. The measured data is available online at for the duration of your licence, which also entitles you to use the API. You can use the API to read Smappee measurement data and import it into other systems. The data will remain available without restrictions for the duration of the licence. The licence can be extended without loss of data.

Smappee Pro must always be installed by an electrician.

How to install multiple Smappee monitors under 1 user account

To install multiple Smappee on one account, you will need to create an additional (new-home for each Smappee. This means that you will have access to all these homes (locations) by logging into that one account
  • To add a new location, tap on ‘Profile’ on the right bottom of the screen.
  • Click ‘Your Homes’
  • At the right top of the screen, press ‘+’
  • Follow the installation process

Working with Multiple Sites


Large multi-site businesses may wish to work with multiple Smappee devices that are installed on multiple locations.

Similarly, an installer may wish to install multiple Smappee devices at different sites of different customers.

In addition, there may be multiple user accounts that need to get shared access to the data. This section explains how to use the app in these scenarios.


If you install a new Smappee device in an environment with multiple sites or multiple users, make sure that you are logged in with the correct username. Also make sure, that you have activated the correct service location.

Watch out! If you use the wrong username or service location, you may corrupt
the new and the existing installations.

Understanding Service Locations

For understanding the multi-site installations, you need to understand the concept of Service Location.

The Service Location represents the place that is measured by a Smappee. In most
cases, the Service Location is identical with the house or site that is connected to a particular utility electricity meter.

Basic Principles
The multi-site, multi-user configurations follow these principles:


  • When measuring, a Smappee device is always connected to a single service
  • All measurements (consumption etc.) are linked to a particular service location.

User Access

  • For viewing and modifying the data of a service location, you need to have a user
    login (user name + password) with access rights to that service location.
  • When you create a new service location (during installation) your user login
    automatically has access to that service location.
  • You may share the access rights of your service locations with other users.
    They then have the same access rights as you have.
  • A user may have access to multiple service locations.

Replace Hardware

  • Consequently, when replacing a defect Smappee with a new device, the service
    location remains the same. Thus, the new device gets connected to the same
    service location. All previous and new measurements remain available at the
    service location.
