VERY VERSATILE: many applications, including pool/hot tub & fish tank water, wood boiler, fridge and deep freezer, livestock water trough, milk, beer, wine, water, steam and pipe temperature monitoring. Additional uses include composting, HVAC/heating/cooling/ventilation management (YoLink smart plugs and switches purchased separately).
KNOW NOW: be informed immediately of off-normal conditions when you easily set up one or more optional notification methods, including SMS*, phone push notifications, emails, siren and/or SpeakerHub audible notifications for your home or business. *Each YoLink app account receives 5 free SMS per month per device plus five. Additional 200 or 500 SMS are available for 2 and 5 dollars per month, respectively. There are no required subscriptions and the app is always free.
Long-lasting Performance: X3 Temperature Sensor features an exceptional 5-year battery life, guaranteeing uninterrupted and dependable monitoring of temperature levels over an extended period without the need for frequent battery changes.
Offline Data Logging: The X3 Thermometer comes equipped with an innovative offline data logger, allowing you to capture and store temperature information even when not connected to a hub. Retrieve and review the recorded data conveniently whenever your device is back online.
YoLink Hub is REQUIRED! This device will not operate without a Hub, not included. Please search B07TQLKQLJ for the Hub
OUTDOOR INSTALLATION REQUIREMENTS — Designed for outdoor use, but not waterproof. Install the device in a protected location away from direct rain, standing water, condensation, and excessive moisture. Covered areas or enclosures may reduce exposure but may still collect humidity or condensation. Prolonged exposure to moisture can damage electronic components and affect device performance.
Customers find the temperature sensor easy to set up and appreciate its long-range capabilities, with one noting it reaches up to 40 feet away from the hub. They like the alerts for critical temperature levels and consider it good value for money. The accuracy and connectivity receive mixed feedback – while some report accurate readings, others note it doesn’t provide constant real-time data, and while some report successful connections, others mention issues with Wi-Fi connectivity. Battery life and durability are also mixed aspects, with several customers reporting abysmal battery life and failures after a few months of use.
