4x Neopixel cushions that can change colour via bluetooth android phone app or when motion sensed.

I want the neopixels to go rainbow in colour when the cushion is stood on or Moves. Motion sensed not pressure switch. When the cushion is not active (Motion sensed) I want the neopixel ws2812b leds to be at 30% brightness Rainbow pattern. Soon as cushion moves with the mpu6050 the lights are 100% bright Rainbow. Also would like the ability to switch the cushions (4 in total) red and green via a Bluetooth app on android phone.3 position switches on;off;on (so 8 buttons in four groups labelled 1 2 3 H). also a button on android app called PLAY that makes the cushions go blue for 20 seconds. How much to code? using a minipro with 15 Neopixels per cushion with a MPU6050 to sense the motion via the IMU. . Range required approx 15 to 20 meters. between cushions. hc05 bluetooth module or better (what do you recommend.) 15 x ws2812B neopixel leds in a string. Minipro atmega328 with 32k of flash for sketch 2 k being bootloader. 2 or 3 18650 batteries for powering for up to 4 or 5 hours. will need a sketch for each cushion or a sketch with the ability to change so i can do the task above i want it to do.
