Common Causes
- Wi-Fi connectivity issues or the monitor losing its network connection
- The monitor is not receiving enough power from the USB source
- Sensor calibration needs time after initial power-on or relocation
- The Alexa app or device firmware is outdated
- The monitor is placed too close to windows, vents, or heat sources, causing inaccurate readings
Step 1: Verify Power and Connections
- Check that the USB cable is firmly connected to both the monitor and the power source.
- Try a different USB power adapter. The monitor requires a stable 5V/1A power supply. Some low-power USB ports on computers or power strips may not provide enough current.
- Look at the LED on the front of the monitor. If it is off, the device is not receiving power. If it is flashing, the device may be attempting to reconnect to Wi-Fi.
- Try a different USB cable to rule out a damaged cable.
Step 2: Check Wi-Fi Connectivity
- Open the Alexa app on your phone and go to Devices. Find the Air Quality Monitor and check if it shows as Online or Offline.
- If the device is offline, verify that your Wi-Fi network is working by checking other connected devices.
- The Air Quality Monitor only supports 2.4GHz Wi-Fi. If your router recently updated and changed settings, or if you have a mesh network that separates bands, ensure the 2.4GHz band is available.
- Move the monitor closer to your router to rule out a weak signal. Thick walls, metal objects, and microwave ovens can interfere with the 2.4GHz signal.
- Restart your router by unplugging it for 30 seconds, then plugging it back in and waiting 2 minutes for it to fully restart.
Step 3: Restart the Monitor
- Unplug the monitor from its power source.
- Wait 30 seconds.
- Plug it back in and wait for the LED to indicate it is reconnecting.
- Allow 2 to 3 minutes for the device to reconnect to Wi-Fi and begin reporting data.
Step 4: Fix Inaccurate or Missing Readings
- After powering on or relocating the monitor, the sensors need 15 to 30 minutes to calibrate. During this time, readings may be inaccurate or unavailable.
- If readings seem consistently wrong, check the placement. The monitor should be on an open surface at table height, away from direct sunlight, heating vents, humidifiers, and kitchen stoves.
- Dust buildup can affect the particulate matter sensor over time. Gently blow compressed air into the sensor vents on the sides of the device to clear any debris.
- Check the Alexa app for the individual readings (PM 2.5, VOCs, CO, temperature, humidity). If only one metric is missing, the specific sensor may need time to recalibrate after a power cycle.
Step 5: Update Firmware
- Open the Alexa app and go to Devices > Air Quality Monitor > Settings.
- Scroll down to check the firmware version. If an update is available, the device should download it automatically while connected to Wi-Fi.
- To force a check, restart the monitor. It checks for updates each time it reconnects.
Step 6: Re-Register the Device
If the monitor still will not connect, deregistering and re-adding it can resolve persistent pairing issues.
- In the Alexa app, go to Devices, find the Air Quality Monitor, and tap Settings (the gear icon).
- Scroll down and tap Deregister. Confirm when prompted.
- Unplug the monitor, wait 30 seconds, then plug it back in.
- When the LED pulses blue (setup mode), open the Alexa app and go to Devices > + > Add Device > Amazon > Smart Air Quality Monitor.
- Follow the on-screen instructions to pair the device again.
Step 7: Factory Reset
- If all other steps have failed, perform a factory reset by pressing and holding the button on the back of the monitor for 12 seconds.
- The LED will flash orange, indicating the device has been reset to factory settings.
- Set up the monitor from scratch using the Alexa app as if it were a new device.
When to Contact Support
If the monitor still fails to connect or consistently displays no readings after a factory reset and fresh setup, the device may have a hardware defect. Contact Amazon Customer Support or visit your Amazon orders page to initiate a replacement if the device is within its warranty period.
