These days, smart home applications offer a variety of new opportunities for customer experience for our tenants as well as for our maintenance teams. We see smart retrofitting approaches to be one of the dominating use cases for innovative digital home applications, showing steep adoption rates in the market and being widely available for everyone today. As Vonovia, additionally, we are testing ways to open up these new opportunities for our tenants – but we need to be sure that the underlying systems and concepts comply with state-of-the-art cyber security standards and withstand potential fraudulent activities to the best possible extent.
