Real-Time Comfort Level Display: The YS8023 features an intuitive screen that instantly shows the current Comfort Level (e.g., Dry, Comfort, Wet), helping you assess indoor conditions at a glance and adjust your environment for optimal comfort.
Max/Min Temp & Humidity Tracking: Monitor extremes with ease! It displays historical maximum and minimum temperature and humidity values, enabling quick analysis of environmental fluctuations over time.
Hub Required for App Functionality: To use the YoLink app and access advanced features, the YoLink Hub is required. The hub connects to the internet and serves as the bridge between the device and the app (YoLink Cloud).
180-Day Cloud Data Storage: Access up to 180 days of historical temperature and humidity records via the YoLink app. Export data for trend analysis, ensuring reliable monitoring of critical spaces like nurseries, greenhouses, or storage areas.
LoRa Long-Range Connectivity: Operates on LoRa technology for reliable communication up to ¼ mile in open air, bypassing WiFi limitations. Ideal for basements, fridges, barns, or metal enclosures (Hub required)
High-Precision Swiss Sensors: Factory-calibrated Sensirion sensors deliver ±0.2°C (±0.36°F) and ±2% RH accuracy, ensuring trustworthy readings without manual calibration.
Custom Alerts via App/SMS/Email: Set personalized thresholds for temperature and humidity. Receive instant push notifications, SMS (5/month per device free), or emails when conditions exceed your limits.

5-Year Battery Life: Powered by two AA batteries (included), the sensor lasts up to 5 years. Low-battery alerts via the app ensure timely replacements, perfect for hard-to-reach areas.
Smart Home Integration: Works with Alexa for voice queries (temperature only) and IFTTT for automated actions based on sensor readings.

A YoLink Hub is required for full functionality - YoLink devices do not use your WiFi, they do not crowd or bog down your WiFi network, but instead they use a unique LoRa-based extreme long-range and low-power wireless protocol unique to most of the smart home industry. The hub connects to the internet and serves as the bridge between the device and the app.
