Log output: No master device defined
**Describe the bug**
In the log there is a "FritzPlatform No master device defined!", but in my config I have:

"FRITZ!Box 7590": {
                    "active": true,
                    "host": "XXX.XXX.XXX.XXX",
                    "port": 49000,
                    "username": " ",
                    "password": "mypassword",
                    "type": "",
                    "master": true,
                    "mesh": false,
                    "readOnly": false,
                    "options": false
                }

Can anyone help?
