Evaluation of key product features

⚖️ Compare features with other products of your choice

This smart meter is installed directly on the existing digital electricity meter and is completely cable-free, as it is battery-operated. Thanks to wireless connectivity via the DECT ULE protocol, it also works in most apartments where the signal can be difficult to reach - the range is up to 40 meters, which is more than enough for the average house or larger apartment.

The user experience is extremely clear: the connection to the FRITZ!Box allows you to view current and historical electricity consumption directly via the app or web interface. You can always export and save your data, and cost analysis and consumption optimization are easily accessible even to those without advanced technical knowledge.

Thanks to its local operation, you are not dependent on external servers, which enables continuous data monitoring and quick responses. Another special feature is the integration with the FRITZ! smart home, which brings even more possibilities for automation and feedback on energy consumption in real time.

The product is designed with the average user in mind, who wants to make their household more sustainable, save on costs, and at the same time maintain complete control over their electricity consumption, without complicated wiring or additional devices.
