VEVOR Bathroom Exhaust Fan, 110 CFM High-Efficiency Ventilation, 1.5sones Low Noise Operation All-Copper Motor, Energy-Saving Bathroom Ceiling Fan, No Need For Attic Access, For Various Ceilings

Can I turn the light on and off with the remote? Trying to see if i can wire to a continuous power source or if it needs to be tied to a switch.

(using remote) If I turn the fan on levels 1-4 I hear them change (increase speed) when I hit 5 or 6 nothing happens (no increase in speed). If I turn on the fan by hitting #5 or #6 they turn on higher than 1-4 for about 3 seconds and then it slows down to speed 4? Anyone have the same issue. Why would it slow down? I tried running my shower with excess humidity - still no increase in speed changing to either speed 5 or 6? I would just rather have it on speed #6 all the time - anyone know?

Can this be direct wired to a switch without using remote?

Is it possible to set the fan to start when you turn the light switch on? Now we have to turn the fan on with the remote control each time we switch it off and it is annoying. I would like a setting to turn light and fan on together with the switch.

I need to install two of these in separate baths, but they are in very close proximity to one another. I would estimate that the fans and the remotes would be about 10" apart. My concern is that the remote in one bath would be turning on the fan in the wrong bathroom. Is this likely?
