So far I’m impressed.

Initially skeptical - was I wrong!

Im a HomeKit (apple) user and wanted a way to integrate this into my system to indicate temperature issues in two large stand-up freezers... And while YoLink does not natively work with HomeKit, there are solutions.

Not being a fan of "cloud based" solutions, I figured Id try this anyhow - as long as their is internet connectivity, this works fantastic! HomeBRIDGE (open source project) makes the connections - and its good! I can trigger other products based upon temperature, humidity, in short get alerts should the temperature rise in a freezer. I lots a full freezer once as the kids left the door open... THIS allows the device to alert if that happens. Once a local bridge solution is available (hopefully forthcoming) Ill give this a 5-star rating. Im really surprised at the quality for something so inexpensive as well.

Ive grown my YoLink system for water and a couple secondary security alerts as well.... and the RANGE, WOW!

This starter kit includes two X3 Temperature & Humidity Sensors and a YoLink SpeakerHub (YS1604).

X3 Temperature & Humidity Sensors


  • Smart thermometer and hygrometer monitors, displays, records, and reports to the YoLink app the current temperature and humidity level
  • In addition to the YS8003 Temperature & Humidity Sensor specifications, the new X3 Temperature & Humidity Sensor incorporates advanced sensor refresh, data streaming, and storage, including over 5000 events stored in offline mode. 


  • Exceptional value; accurate indoor temperature & humidity sensor in one smart device at a great price

  • LCD display shows current temperature (Celsius or Fahrenheit) and current humidity (%)
  • Portable; may be placed anywhere in your home or wall-mounted
  • High/low temperature alerts
  • High/low humidity alerts
  • Historical temperature and humidity graphs displayed in hourly, daily, weekly and monthly figures
  • Exportable data

  • YoLink's industry-leading long range communication and low-power operation
  • Create customized alerts, to be informed of high- or low-temperature 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 or the SpeakerHub, our audio, talking and sound/tone-playing hub
  • Self-calibration available via the YoLink app
  • IFTTT Integration: Use the IFTTT service ( to create custom automation with YoLink and third-party devices, tailored to your particular needs and your IoT devices. Trigger IFTTT applets based on high or low temperature or humidity set points reached (when the device alerts; when it detects a high or low temperature or humidity level, per your pre-set parameters). Please note: IFTTT is a subscription-based service, with only three free automations.
  • Alexa Integration: Voice query Alexa for the temperature (only; humidity not supported at this time). Triggering Alexa routines is not supported at this time.
  • Home Assistant integration: automate and integrate, using the Home Assistant automation platform


  • 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
  • Monitor the temperature of rooms or buildings without temperature control, for example, receive a low-temp alert before water pipes freeze
  • 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
