📶 Bluetooth Connection

  • Please make sure Bluetooth is enabled on your phone.
  • Power on your PuffiAir device.
    ⚠️ If using a power bank, ensure it supports automatic power delivery — some power banks won’t turn on unless you press a button.
  • The app will automatically scan and connect to the nearest PuffiAir device — no tap or pairing required.
    👉 If no device appears or connection seems delayed, you can pull down the screen to manually refresh the scan.
  • Once connected, you’ll see the device name (e.g., PuffiAir_XXXX) shown at the top of the screen.

📊 What You Can See in the App

Once connected, the app displays the following real-time data, updated every 10 seconds:

  • PM2.5
  • PM1.0
  • PM10
  • PM4.0
  • VOC Index
  • Gas Level (ADC)
  • Temperature
  • Humidity
  • Air Quality Level (Normal / Warning / Danger)

All readings are color-coded for easy interpretation.

📈 Historical Data and Export

  • The app automatically stores one data point per hour, up to 1 year.
  • Tap on any sensor to view history in:
  • 24-hour view
  • 7-day view
  • Monthly average view

⚙️ Settings Page Features

In the Settings page of the app, you can:

  • Change the language
    This setting also affects the voice alerts played by the device. For example, if you choose Japanese, the spoken warnings will be in Japanese.

  • Configure Wi-Fi, MQTT, or temperature/humidity offset
    These settings are only available when the device is in AP Mode, and your phone is connected to the PuffiAir Wi-Fi hotspot. APPview

🔄 How to access AP Mode

To enter AP Mode:

  1. Long-press the physical button on the PuffiAir device for 10 seconds.
  2. The LEDs will blink to indicate AP Mode is active.
  3. On your phone, connect to the Wi-Fi network named PuffiAir_Config.

Once connected, open the app and go to the Settings page. The fields for Wi-Fi, MQTT, and sensor offset will now be visible and editable.

ℹ️ These settings are saved directly to the device. The device will automatically reboot after saving Wi-Fi or MQTT changes.

🔒 100% Local and Private

  • All sensor data stays on your phone — no cloud, no account, no tracking.
  • The app runs completely offline.
  • Bluetooth communication is temporary and local only.
