Yes! What you have seen is a smart plugboard that converted by ESP32 master board and controlled by BLE of ESP32. As a fan of Arduino, I am worried about that ESP32 has been supporting Wi-Fi and Bluetooth but without libraries files for Arduino. However, the smart plugboard can control many slave equipment at the same time. Trust me, I have made two and tested them.
Am I the first one to DIY with BLE of ESP32?
