Smart Home Data

As many as 400 private households within the Smarter Together project area can install ready-to-use (“plug-and-play”) smart home sets. These sets are provided by the project partner Securitas GmbH. The sensors used measure and collect temperature and air humidity data in two rooms per household. Users can trace their individual measurements over time in a dedicated app.

Using a secure mode, the indoor climate measurements for all participating households is transferred to a smart data platform. There – in conjunction with information about the local weather conditions provided by German weather service DWD – the data is analysed.

The goal of this anonymised analysis is to identify how the parameters weather, energy refurbishment and residents’ individual ventilation behaviour influence a healthy and comfortable indoor climate.

Long-term monitoring also makes it possible to identify possible energy savings due to optimised heating and ventilating behaviour.

All information is anonymised before analysis begins. Accordingly, it is not possible at any time to draw conclusions about individual households or persons.

Residents who are interested in using a smart home set can find out in detail about the planned data analysis during the process of registering the program. They can also state their consent to – or refuse – the planned data usage.

Type of Data

The installed sensors collect temperature and air humidity measurement data in two rooms per household.

The frequency of data transfer is variable. It occurs whenever the measured parameters vary by 0.5 units, but is performed at least once per hour.

Data Classification and Privacy

Data transfer is encrypted. The measurement values are used anonymously and exclusively for the project analysis described above.

Project partners use the results of the analysis in an anonymised and aggregated form.

It is therefore impossible to draw any conclusions about individual apartments, persons or behaviour patterns.

What happens with the data?

This anonymised analysis is supported by the Technical University of Munich (TUM) from a scientific perspective. The goal of this analysis is to identify how the parameters weather, energy refurbishment and residents’ individual ventilation behaviour influence a healthy and comfortable indoor climate.

Long-term monitoring also makes it possible to identify possible energy savings due to optimised heating and ventilating behaviour.
