Hey, I got an Echo 3rd gen for a long time which I just use as a speaker, I just got my hands on 4 Echo dots 3rd gen, I know have one in each room in my apartment which is cool for playing music anywhere but can anyone recommend any other cool usage I can do with my entire home being mapped with them? I don't have too much other smart home devices (shutters, heater and some lights but not all), is there maybe a modding community which got cool functionality I can add? I got my home server and if I could connect it can I create some cool stuff or something?
