I now have a wireless connection (via WiFi) between the shed and the house. By pressing a button it can be announced that dinner is ready.

The ESP8266 (on a D1 Mini) serves as both a web server and a web client. When the web server receives a signal from a client, it responds by playing an MP3, for example "Dinner is being served".
Multiple MP3s can be played this way. The MP3 module that does this is very convenient to use.

Components I used
A D1 mini.
A handy plug to connect audio/video.
A special MP3 module.
A power amp.
A loudspeaker that goes nice and fast.

MP3's (some examples)
