@wishmaster270 Wow thank you very much , im completly new to this and first of all this helps me out very much and im going to try to make my own module showing an API from our school , is it okay if i ask you questions when i need help?
and btw. rrealllyy appreciate your help :)

Hi, for school we need to build a project using an Arduino.
For me the Arduino itself is boring thats why i decided to build a MagicMirror using Raspberry Pi and i wanted to integrate functions from Alex, different Sensor-stats like Temperature and the PIR
But everything i tried didn’t worked and now im Wondering if it’s even possible to connect both.

Sensors i have and want to use :
DHT11, for Temperature in Room,
HC-SR501, for Timeouts when not standing infont of it
ESP8266 ESP-12E, to Connect to the Alexa

Im Using a Raspberry Pi3
and an Arduino Uno R3 with the ELEGOO Ultimate Starter kit and a few other modules.

i would really appreciate if someone helps me and if you have good ideas to what i should add to get a good grad xD i would really appreciate it aswell.

This is my Current Config :
