Milestone reached. Wanted this since I was a Kid =D
I am too poor to buy all the stuff I want, and I am to stupid to code something I want to exist. I spent 90% of the time googling error messages I dont understand and c&p code I cant read. But at least I have a lot of ideas and some time 
Features:
- Own AI Assistant, own Data – No Alexa, no Cloud
- All Controlled by Voice, Automatons or one remote
- A Fake Hue Ambient Lighting System designed from scratch
- Cheap with (essential) Parts, easy to Build (no Coding, no Soldering)
- Unlimited Possibilities regarding Customization, Integration and Extension (APIs…)
- Connections to external ecosystems (Kodi, Hue,…)
- Features and Software Evolving with its Communities
Parts:
- Voice Assistant: RasPi4 + ReSpeaker 4-mic-array with Mycroft.ai
- Server and NAS: Intel NUC with OpenMediaVault and Home Assistant
- Light: Fake Hues with Milights via diyHue and esp8266_milight_hub
- Client: Vero4K with OSMC (Kodi Fork)
- Plugs: Teckin SP21 flashed with Tasmota via Tuya-Convert

Further Ideas:

- A NUI Gesture Control System with Nvidia Shield(?)
- A Tablet based Interface for Playful Light Interaction
- Build a Nice Robot Body for Mycroft
Thanks, keep on Going!
