The whole system was set up quite well. At the beginning there were small problems - I wanted to test the kit without Door, but that seems to be not provided. Only when I door installed everything worked as desired. I have two additional sensors installed which is relatively easy to set up left (with the near 1m to the base is a little stupid when already mounted sensors because we have built a few outlets with us. This method should perhaps reconsider). Nevertheless, since today and for updates of all sensors everything is working properly. I'm very satisfied and the app will also continually evolving. My conclusion so far: recommended.
