Homewerks Worldwide7130-08-BT Bluetooth Bath Fan & Speaker in One with LED Light

Does it “beep” when you turn on the light in the middle of the night?

Will it work with echo dot? If not will it work through a smart things hub and then alexa?

Our contractor lost the paperwork to this now we can’t figure out how to connect it. Can someone help?

Is the the cover plastic or metal?
