About this item

• 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.
• NO WIFI WORRIES! And no WiFi required! YoLink utilizes a unique wireless format very different from WiFi. Based on LoRa, our devices boast 1/4 mile open-air wireless range, long battery life, and superior obstruction penetration (allowing for placement inside freezers, etc.). Communication is two-way encrypted, protecting your network security and privacy.
• 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.
• BEGIN INTELLIGENTLY! For complete functionality, including app operation, a YoLink hub is necessary. However, your hub is adaptable with an expanding range of smart devices for both home and commercial use, such as intelligent locks, smart lighting switches, and beyond! Look up B09FSS95G9 for a SpeakerHub (our audio-enabled 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).
