INTRODUCTION: 

• Smart, indoor/outdoor, thermometer and hygrometer monitors, records, and reports to the YoLink app the current temperature and humidity level

FEATURES: 

• Designed for outdoor use, suitable for indoor use
• Portable; may be placed anywhere in your home or wall-mounted
• Temperature and humidity displayed on the YoLink app
• Designed with home and light commercial applications in mind, precision components are utilized, to provide the accuracy you demand. Temperature accuracy of  ±0.54° F and humidity accuracy of ±3% RH
  
• Extended operating range of -22° to 158°
• Self-calibration available via the YoLink app
• High-temperature/low-temperature alerts
• Historical temperature and humidity graphs displayed in hourly and daily figures
• Wireless operation; no 120V outlet or wiring required
• Battery-powered (two Lithium AAA batteries, included)
• 2 or more years of battery life, compared to 1 year for other brands
• IFTTT & Alexa Integration: trigger IFTTT applets based on high or low temperature set points reached (when device alerts). Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time. YoLink's industry-leading long range communication and low-power operation

BENEFITS: 

• Exceptional value; accurate temperature and humidity sensor in one smart device at a great price
• Works with the convenient and user-friendly YoLink app
• Know the current temperature and humidity level at the sensor’s location. Check remotely using the YoLink app, anytime and from anywhere
• Create customized alerts, to be informed of high or low temperature and/or humidity levels via emails or app push notifications
• Create custom automations using the YoLink app, to trigger responses from other YoLink devices, such as the Siren Alarm
• Use the IFTTT service () to create custom automations with YoLink and third-party devices, tailored to your particular needs and your IoT devices (IFTTT is a paid service for more than 3 custom automations)
• Compact design allows for placing the sensor where others may not fit
• Easy to install and portable; move to other locations as needed
• Lower cost of ownership than other technologies; low-power operation means batteries may last over 2 years, compared to 1 or less from other brands
• Carefree maintenance, with more years between battery replacement
• Low-battery alerts give you advanced warning that it is almost time to replace the batteries
• Extremely easy and fast installation using the YoLink app with Scan & Play

APPLICATIONS: 

• Use the YoLink smartphone app to remotely monitor the temperature and humidity of your home, rental property, condo, summer home, or business (internet connection and YoLink Hub required)
• YoLink’s industry-leading long range communication allows for placing the sensor in your out-buildings, separate garage building, barns, greenhouse, etc.
• Place one in each room your wish to keep an eye on the temperature and humidity. 
• Place the sensor in a basement or other area subject to mold and mildew growth due to high humidity levels. Identify problem areas before expensive repairs are required
• Use the sensor and app automation features to automatically turn on the exhaust fan in your bathroom during hot showers and baths
• Use the sensor and app automation features to automatically turn a humidifier or dehumidifier on or off based on sensor levels
• Monitor your cigar humidor, wine cellar, or any other temperature- and/or humidity-sensitive item or area
• Place inside a refrigerator or freezer, to prevent the loss of expensive refrigerated and frozen foods due to equipment failure or power loss. Also, commercial walk-in coolers
• Monitor the temperature of rooms or buildings without temperature control, for example, receive a low-temp alert before water pipes freeze
• Commercial applications include IT and mechanical rooms and other spaces that are critical and/or require temperature and/or humidity monitoring
• There are numerous pet care applications: 

• For reptile tanks (turn on a heat lamp if the temperature gets too low, or turn off the lamp if it gets too hot)
• Place one an outdoor dog house, to know if it’s too cold for them
• Place in a barn, to ensure your horses or livestock are comfortable and safe
• Receive alerts if sensor levels fall outside of your customized ranges
