+/**
+ * BluettiADV Monitor Example
+ *
+ * READ-ONLY monitoring of newer (encrypted) Bluetti devices — Elite / V2 /
+ * EP600 etc. — via their BLE advertisement broadcast. No connection, no pairing.
+ *
+ * Setup:
+ * 1. Get the 16-byte AES key (32 hex chars) from the BLUETTI app or the device
+ *    Webserver (look for the Bluetooth data / developer section).
+ * 2. Get the device's BLE MAC address (a BLE scanner app shows it; the unit
+ *    broadcasts manufacturer data starting "06 0F").
+ * 3. Fill both in below.
