And more
• Stream your phone's sensors to the device: accelerometer, gyroscope, compass, orientation, GPS, barometer, light, microphone level, touchpad
• Rules and alerts: "notify on ERR", "temperature > 30 → FAN=1"
• Record sessions and replay them with the same timing
• BLE explorer: service/characteristic tree, read/write/notify
• OTA: Nordic DFU, ESP32 over BLE and Wi‑Fi
• Web bridge: use the terminal from your computer's browser
