Well, you can use a Raspberry with Max2play and LMS (Logitech media server) control this with Iobroker. Connect the raspberry to your audio system run sqeeuzplayer on your phone to sync the music with LMS.
Now you can use HUE Essentials Disco option to sync your HUE light with the music playing on your audio system and your phone.

For sure check out MAX2play, with a brunch off raspberry's with DAC hat, you can play music all over your house (incl. Airplay, Spotify, internet radio etc..)

@levos67 ,

On Github, there is a clear explanation of the ZK protocol.

MY only problem is that i do not know where to start with a iobroker adapter creation, if someone can help me to start with it or point me where to start, that will help.

I have the C3-100 and C3-200 door acces controller at home, the controllers contains a LAN and a RS485 for communication and control from a PC, software is only for windows availabel. BUT there is a compleet SDK for intergration in other software, I DO HAVE NO CLUE if this is usefull for iobroker community/users/developers to make a intergration in iobroker??

The cards work great for a price of $62 (C3-100) and $75 (C3-200) and have all options for acces/level/users (no i am not a reseller)

i can provide all info (is also online on ZKteco site) software , SDK and hardware for testing, or maybe the SDK speaks for itself (again, i got no idea how to use a SDK)
