Hello, unifi newbie here.. I just got unifi set up yesterday in the living room. If i would like to watch hypptv in another room on a another TV (same channel), what device do I need? And how to set up?

Another question is my Motorola DECT phone, when I turn off the switch to stop charging, the phone cannot make/receive calls anymore. How do I stop charging but still be able to use the phone?
