Remote dingdong-server
Whenever someone rings the doorbell I want to be notified. An ESP32 at the doorbell initiates a telnet connection with my dingdong server.
The dingdong-server is an ESP8266 Fritzelboard. This server will:
- power up the dingdong in my room, producing a pleasant very loud melodious sound
- do a lot of other important things
