About this item

• START SMART! A YoLink hub is REQUIRED for full functionality, including for the app to work, but your hub is compatible with a growing family of smart products for home and business, from smart locks to smart light switches and more! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
• 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.
• THAT WAS EASY! After the hub is set-up, adding new devices takes just a couple minutes with our app's convenient and lightning-fast Scan & Play QR code scanner. No more waiting for WiFi! Installation can be as simple as hanging the sensor on a nail or command hook, or by placing on or inside the box or enclosure to monitor.
• Experience peace of mind with no concerns about WiFi connectivity! YoLink operates without the need for a WiFi network, utilizing a distinct wireless technology not based on WiFi. Our products feature an open-air wireless range of 1/4 mile, extended battery life, and exceptional ability to penetrate obstructions (ideal for use in freezers, etc.). All communication is securely encrypted in a two-way manner, safeguarding your network security and personal privacy.
