NFC-Tag

[high relic]

I want to use an NFC tag in my smart home to start the PC (wake on LAN/via power action), then turn on the lights and start my Sky receiver.

I have two smart sockets for power actions, and the lights are also smart home.

Sounds like you want to start building an automation that utilizes your tag_scanned event as a trigger to perform those actions

Are you asking if you can broadcast a message to your speakers via Home Assistant or something else

[high relic]

Yeah, a common way to do that is using the alexa media player integration

Your best route is to search for integrations that match what you want to do. That's the software that connects the outside world and devices into Home Assistant.

Alexa media player is here: https://github.com/alandtse/alexa_media_player/wiki/Configuration
WOL is here: https://www.home-assistant.io/integrations/wake_on_lan/

If I'm not mistaken, I just linked both of the integrations installation instructions. Have you taken a look and followed them?
