Hello, I am wondering if there is a way to completely lock every device except for my own from being able to adjust volume or any other power controls from they’re own devices while using the same network, and if so how?
No you would need to have your Nest mini and mobile device on a different WiFi network to stop others having control options. You can turn off cast media notifications so others on the same network don't see a notification that you are using the device but this wouldn't stop them from being able to start casting directly to it.
