⚡ Easy DIY Troubleshooting & Common Fixes

🔧
Inconsistent CO2 readings or readings stuck at a fixed value.
prob_01
Common root cause: Initial calibration needed or an environment with poor ventilation keeping CO2 levels high.
Step-by-step solution: 1. Leave the sensor powered on in a well-ventilated area (outdoors, if possible) for 24 hours for automatic calibration. 2. If the issue persists, check for firmware updates in the app.
💡 Pro tip: Avoid placing the sensor in enclosed, unventilated spaces for extended periods, as this can affect calibration.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How to calibrate the CO2 sensor? cfg_01
Most generic NDIR sensors perform an initial automatic calibration (up to 24h) and a background calibration (auto-baseline) in fresh air environments (~400ppm CO2). For specific manual calibrations, consult your model's manual or the Tuya app if this option is available.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support for warranty service if, after following all self-resolution and verification steps, the device exhibits persistent functional failures, such as not powering on, failing to connect to Wi-Fi despite a strong signal, or showing clearly abnormal and inconsistent sensor readings that do not correct with ventilation or calibration. Manufacturing defects not resolvable by configuration or proper use are covered under the seller's warranty and marketplace return policy.
