Troubleshooting and light patterns for Ring Air Quality Monitor

Ring Air Quality Monitor tracks air quality, temperature, humidity, PM2.5, and CO levels in your home. Use this article to troubleshoot common issues and identify LED light patterns.

Troubleshooting

Issues scanning the QR code

• Make sure your mobile device operating system (OS) is up to date.
• Make sure the camera lens on your mobile device is clean and free of debris.
• Make sure the QR code on Air Quality Monitor is not damaged, dirty, or covered in debris. Wipe it with a damp cloth or paper towel if needed.
• Make sure there is proper lighting in the room. If the room is dark, turn up the lights or move to a more well-lit area.
• If the in-app QR scan continues to fail, use your mobile device's native camera to scan the QR code. This will open the Ring app with the QR code already scanned.
• If these steps do not resolve the issue, contact Ring Customer Support.

Resolve software update failures

• Update your mobile device operating system (OS). Software updates use Bluetooth Low Energy (BLE) and require a current OS version.
• Stay within one to five feet of Air Quality Monitor during the update. BLE is short-range.
• Install fresh batteries. If Air Quality Monitor was previously set up, replace the batteries and try again.
• Power cycle Air Quality Monitor: Remove the batteries, wait 10 seconds, re-insert them, and try again.
• If the issue persists, contact Ring Customer Support for further assistance.

Air Quality Monitor is stuck in Waiting to Join

If Air Quality Monitor remains in a Waiting to Join state for five minutes or more:

• Make sure Air Quality Monitor has fresh batteries. If Air Quality Monitor is new, the batteries should be fully charged. If it was previously set up, replace the batteries and try again.
• Power cycle Air Quality Monitor: Remove the batteries, wait 10 seconds, re-insert them, and try again.
• If you have a supported Sidewalk bridge or gateway nearby, move Air Quality Monitor closer to it.

Air Quality Monitor goes offline

If Air Quality Monitor shows as offline in the Ring app:

• Make sure Air Quality Monitor has fresh batteries. Replace the batteries and try again.
• Power cycle Air Quality Monitor: Remove the batteries, wait 10 seconds, re-insert them, and try again.
• If the issue persists, contact Ring Customer Support.
• Air Quality Monitor is not reporting on a regular basis
• Air Quality Monitor reports temperature, humidity, PM2.5, and CO readings every 15 minutes. It also reports temperature immediately if it changes by ±2°F (±1°C), and humidity immediately if it changes by ±5%. This is expected behavior.
• Check your signal strength and follow the troubleshooting steps in the Device goes offline section above if Air Quality Monitor is not reporting at all.
• If readings are not updating for more than 15 minutes, power cycle Air Quality Monitor: Remove the batteries, wait 10 seconds, re-insert them, and try again.
• If the issue persists, contact Ring Customer Support.

Temperature or humidity thresholds are not changing

• Check your signal strength and follow the troubleshooting steps in the Device goes offline section if needed.
• Open the Ring app, go to Device Settings, and confirm your threshold changes appear in the Ring app. If they do appear in the app but not on Air Quality Monitor, contact Ring Customer Support.
• If Air Quality Monitor has poor Amazon Sidewalk connectivity, changes to temperature or humidity thresholds might take longer to apply and the app might show a loading circle until the connection improves.

Key reminders

• The device serial number (DSN) is located under the batteries. Remove the batteries to find it.
• Keep Air Quality Monitor away from direct sunlight, heat vents, and cooking areas for accurate readings.
• Air Quality Monitor needs time to calibrate after setup. Allow up to 24 hours for readings to stabilize.
• If readings appear inaccurate, make sure Air Quality Monitor is not in an area with high airflow.
• Air Quality Monitor has a temperature accuracy of ±0.81°F (±0.45°C) and humidity accuracy of ±4.5%.
• Air Quality Monitor is not a replacement for a dedicated CO detector.
• Temperature: High 78.1°F (25.6°C) and Low 39.9°F (4.4°C)
• Humidity: High 60% and Low 30%
• PM2.5: Good is at or below 35.0 μg/m³; Poor is above 35.0 μg/m³
• CO: Good is at or below 9.0 ppm; Poor is above 9.0 ppm
• For humidity above normal limits, increasing ventilation might help improve air quality.
