Your energy dashboard in your pocket

With the Smarty+ application, you can track your energy consumption and production in real time, wherever and whenever you like – whether electricity, gas, water or even district heating, measured by smart meters connected to your Smarty electricity meter(s). Discover more about the available data on our DATA INSIGHTS page.

Save money and reduce your environmental footprint

Thanks to your consumption data available in real time on your application, you can monitor your consumption, detect any anomalies and make savings.

Do you have a photovoltaic installation? Optimise your consumption by adjusting it to the time of production and thus reduce your environmental footprint.

Take part in the energy transition

By agreeing to share your data with your distribution system operator (see list of Luxembourgish DSOs), you actively contribute to the success of the energy transition by providing valuable high resolution and near real-time information that allows a better analysis of the usage of electricity networks.

Local access to your energy data

Do you have already another device connected to the P1 port of your Smarty meter? No problem! On the back of the Smarty+ dongle you can find a replication of the P1 port where you can connect an additional device to access the smart meter data locally.

Connect your Smarty+ in just a few seconds

To activate your Smarty+ dongle, be sure to have your WiFi password and your P1 encryption key of your Smarty electricity meter ready.

After connecting your dongle to the P1 port of your Smarty meter, follow the instructions in the Smarty+ application to activate its communication. As soon as the communication is established, the dongle decrypts the data collected by the Smarty meter and sends it to your smartphone.

Additional ports on the back of the dongle (P1-Out and Digital Out) will also allow you in the future to access your decrypted energy data locally and to control and connect other devices.

Request your P1 encryption key

Priority to the security of your data

The data of the Smarty meters (displayed via an OBIS classification) are protected by an encryption key, which must be entered during the activation process to allow the Smarty+ dongle to read them correctly. This encryption key is available upon request from your distribution network operator.

The communication between the Smarty+ dongle, the cloud and your mobile application as well as the protection of your data in the cloud are subject to the most modern security standards, allowing only those persons and companies to whom you have explicitly given your consent, to have access to the specified data.
