To share control of the burglar alarm system, both users must be part of the same household in Home + Security. Once the first user has registered the PIN code in the Home + Security app, you can also grant control of the burglar alarm system to other members of the household. The first and second users must: 1. Go to “Manage my home” 2. Enter the room with the MyHomeServer1 object and select it 3. The first user will select “Grant control” by displaying a QR code 4. The second user will select “Take control” to frame the QR code. For more information, see the tutorial: https://www.youtube.com/watch?v=_qEkuebND6U&list=PLlaDNT-XSIbcAbndD7ENMUMoSZXDKOm0o&index=5
