The FRITZ Smart Energy 250 AVM offers a power sensor for digital electricity meters that directly reads consumption data and makes it available in the smart home. Besides its use in the FRITZ! Smart Home system... We are currently also testing the integration of the sensor into Home Assistant., in order to evaluate the energy data there and integrate it into automation systems.
In a separate article We have already extensively tested the FRITZ!Smart Energy 250 and described the setup, installation and evaluation of the consumption data in the FRITZ! system.
What is the FRITZ! Smart Energy 250?
The FRITZ!Smart Energy 250 is a battery-powered sensor that uses the optical interface (infrared LED) The digital electricity meter records data on current power consumption and meter reading. This information is transmitted via DECT radio to a compatible FRITZ!Box sent. In our test, the setup via the FRITZ!App Smart Home Both via the web interface and on mobile devices, it is particularly convenient and self-explanatory.
Thanks to the integrated magnet, the sensor can be attached directly to the meter and is immediately ready for use. After setup, the app immediately displays consumption, battery level, and connection status.
Keeping an eye on electricity consumption – analysis & smart home functions
The FRITZ!App Smart Home The FRITZ!OS interface offers an easy-to-understand display of consumption data – both in real time and over time periods such as days, weeks, or months. Furthermore, the data can be accessed via the service. MyFRITZ!Net Store and analyze long-term.
The test showed that the connection of the FRITZ!Smart Energy 250 via DECT stable It works and the consumption display also works in more complex scenarios, such as in combination with Balcony power plants, can be used effectively.
Currently, bidirectional meters are being used to... feed-in meter reading The FRITZ!Smart Energy 250 does not evaluate or display this data. Its current functionality is limited to recording energy consumption. We hope that AVM will add this feature in a future software update.
Integration with Home Assistant
While the FRITZ!Smart Energy 250 is primarily intended for the FRITZ! ecosystem, it can also be used elsewhere. indirectly integrate into Home Assistant: About the FRITZ!Box smart home integration In Home Assistant, data from the FRITZ!Box is queried and then made available as sensor entities.
battery displays the current charge level of the batteries used in the sensor. energy This displays the current consumption meter reading of the digital electricity meter. Performance, Tension and current These correspond to the current measured values recorded by the electricity meter and read by the FRITZ!Smart Energy 250.
So that the consumption figures in Home Assistant Energy Dashboard For the entities to be displayed, they must be correctly assigned. Network connection The entity will be energy assigned while the Network power the entity Performance is assigned.
After this configuration, the measured values and consumption data are available for Automation, Dashboards and Notifications Available in Home Assistant.
Conclusion on FRITZ! Smart Energy 250 and Home Assistant
The FRITZ!Smart Energy 250 is a practical current sensor, The sensor reliably and conveniently integrates consumption data from a digital electricity meter into your smart home. Setup via the FRITZ!App Smart Home is intuitive, the consumption data is displayed clearly and can be accessed remotely. For users with a DECT-enabled FRITZ!Box and a compatible digital meter, this sensor is a valuable addition. To make energy consumption visible and to uncover potential savings.
Combined with Home Assistant This data can also be used and in Automation or consumption analysis to integrate, which further increases the practical benefits.
