📤 Sending Sensor Data to OceanRemote Cloud

Now that you can read sensors and connect to WiFi, let's send data to OceanRemote where you can see it from anywhere!

🔑 Getting Your Device Token

1. Log in to OceanRemote at oceanremote.net
2. Go to "Your Device" page
3. Select ESP32 board type
4. Enter your WiFi credentials
5. Click "Generate Code"
6. Copy the token (starts with "oc_perm_...")
