LED Strip chip model: WS2812B

every LED have R,G,B colors:
every LED cost R: 20mA+G: 20mA+B: 20mA=60mA

if you using 1 meter = 30 LEDs 
total cost:60mA*30=1800mA=1.8A  so chose DC5V 2000mA power supply

if you using 10 meter, so will use 300 LEDS
total cost:60mA*30*10=18000mA=18A  so chose > DC5V 18A power supply

 led strip chip model: WS2811 use DC12V 

powe supply DC12V  power supply not DC5V

CAN i use these model with A4 model ?

you can confirm with your LED strip supplier, whether the LED strip DATA pin is 5v level, if it is, ok no problem with A4 module.

Do you meaning pin data shoud be  5 volt?

yes.

im getting an error using this script "warning esp_intr.h is deprecated, please include esp_intr_alloc.h instead"

you can update your ESPHome to newest, test again, if have problem, please upload your screen photo.
