Basic Smart Home Set Up Help

[lucanachname]

So I want a basic smart home setup for my entertainment/working space.

The Devices are:

- Tower PC
- LG 4K Monitor
- LG OLED TV
- Studio Monitors
- Audio Interphase with Microphone
- Lightstrips

I have exactly one power source. I want to turn on/off everything with my smartphone in special combinations.

There are four Things I want to be able to do:

- Turning off/on light
- Turning PC, and Monitor off/on (Working)
- Turning PC, Monitor, Studio Monitors and Audio Interphase with Mic on (Creative Work / Gaming)
- Turning PC, Studio Monitors and OLED TV on/off while connecting the PC to the OLED TV (Gaming / Entertainment)

So I was thinking about connecting one eve energy strip to the power source. Also I know I need an Display Port switch to change the Screens. Eve Energy Strip has 3 places for devices. But tbh I don't know how I am supposed to go from there. It's pretty complicated for me tho

Do have an Idea how to achieve this? You can answer in german if you want to

Thank you very much
