The ESP32-CAM has some spare GPIOs which could be used for this 8like for controlling an external LED controller. How ever, the real challenge for you is how to push the button. This either needs some mechanical pusher or you rip it apart and short circuit the button on request. |

Modern water meters have an LC-Display showing nothing at all. After pushing a button (usually round and black) the numbers appear. How could one solve this challenge?
