Key features

• 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).
• 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.
• 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.
• 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.
