Moin guys
I'm so desperate that I turn to you now and I hope there are a few specialists here.
My brother has a chrome cast on the lower floor in the house. We have together the Fritzbox 6490 where all devices are connected to a Wi-Fi.
The problem is that anyone can stream to the Chromecast which is in the Wlan network. For example, if I accidentally click on the "on tv stream" button in my room on Youtube, the TV automatically goes down and transmits my desktop. The same problem is even with the phones so once on the button and I take over control of his TV as it is automatically switched to or switched.
I've followed every tutorial on the net / Youtube and tried to lock other people out with the Google Home app as well. If I set up the cast via the app from the phone of my brother and disable the control for others I can still access and even change the settings of the part via home app. I can't delete any devices that have ever been connected and even my Youtube on the laptop, I can't ban streaming, have even searched for a program which should block a connection, unfortunately, all unsuccessful
I would like to release the cast only for the phone and the laptop from my brother. The TV is not connected to the Wi-Fi if that helps.
Unfortunately this is not possible.
