In this project I made the old rotary phone smart. It sends the rotated numbers to an MQTT server. Later this information can be used to automate everything.

The project based on this library https://github.com/markfickett/Rotary-Dial
It counts the pulses of the phone then retuns with the result.
- After wiring the right wires to the ESP32 microcontorller, you need to upload the compiled code to the board.
- At the first start you can connect to the offered WiFi AP of the board (name: rotaryphone).
- You can reach the Web interface on the IP of the board: 192.168.4.1
- set the WiFi and the MQTT connection on the web interface
- after save it will reboot and connects to the Wifi and MQTT
- Rotated numbers will be sent over MQTT
After a dial there is a 2 secs timeout before sending out the number. It makes possible to dial longer than 1 digit numbers.
TODOs:
- make available to have some sound in the handset (for ex. mp3)
- read the onhook/offhook events
- trigger to ring the phone over MQTT
