Hi! Are your Yo-Yo machines close to your WiFi router? It could be that if they’re too far away, they can’t connect and reset themselves.

It’s worth checking if both of your devices are successfully paired and connected to the internet. You can do that by tapping the BOOT button on the ESP32 module, and checking if the blue light flashes on the other ESP32 module, and vice versa. If that’s all working, double check your wiring, particularly the piezo sensor part. Hope that helps!
