Turn device on/off, select zone, control volume through BluOs app?

Does the Bluos app allow the user to turn the AVR on and off? Turn individual zones on and off? Control volume? I’m considering a used NAD T777v3 (currently have a Yamaha RX-A2070 42050D), but want to find out if the BluOS app primarily for controlling playback (like Sonos), or if it also supports these basic functions. Thoughts?
