does this shower head come with instructions?

Yes it does come with instructions, and also photos for installation illustrations.

Can this be used with any type of controls? Such as moen ?

Yes, you can use your own valve / controls as long as the valve has three independent outlets to supply the shower head. You would need to run 3 rough in pipes from the valve / control all the way to ceiling (Shower head location). To utilize ALL functions of this shower head, you would need valve that each function is independent of the other (i.e. you can have one function, two functions, or three functions @ the same time). We do sell these valves also.

Can the led controller be connected to smart home technology?

Yes, The LED Lights are controlled by a remote control, which you can be synchronized with smart home technology.

Do I need a knob on the shower wall to turn this on/off?

Yes you need a knob to control the showerhead. This listing is for showerhead only. We have other listings that comes with the showerhead and handheld. Please refer to the below product listing: https://cascadashowers.com/collections/luxurious-recessed-shower-head/products/cascada-classic-design-31-inch-600mmx800mm-large-rain-shower-set-with-waterfall-led-rectangle-recessed-ceiling-mount-4-function-shower-head-with-remote-control-stainless-steel-polish-finish-3

We are going to use 23"x31" Luxurious Recessed Rain & Waterfall LED Shower Head - 4 mode. Specification sheet shows Flow Rate 1.8 gpm for each function. My question is: What will be Flow Rate if will use 4 mode at the same time? It can not be 1.8 x 4 = 7.2 gpm. In NYC Flow Rate for 2 shower head is 3gpm.

The flow rate for 1 mode of the shower head is 1.8 gpm, however, the maximum flow rate if want all functions to work together at the same time depends on the mixing valve / controller.  If you are using our Thermostatic Mixing Valve (4Konb, 5Knob, 6Knob or 7 Knob), then the maximum flow rate for all modes at the same time will be 5.7 gpm.  This is because our mixing valve comes with regulated cartridge (Vernet CA43G ).

For 23"x31" Luxurious LED Shower Head - 4 mode in specification indicated 1.8 gpm flow rate for 1 mode. What will be Flow Rate if will work all 4 mode? Max flow rate for 2 shower head at the same time in NYC is 3 gpm. Please, answer me as soon as possible. Regards, Natalya Beskina

can all functions be used at the same time? Does it need/come with a specific valve?

This listing is for Shower Head only.  1,2, 3 or 4 functions can be used at the same time.  You would need to run 3 independent rough in pipes from the control valve (not included) to the shower head.  We do have other listing that comes with Control Valve.  PLease refer to these two listings:
