About this item

• 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).
• GET INFORMED IMMEDIATELY: easily set up optional notification methods for off-normal conditions including SMS, phone push notifications, emails, sirens, and SpeakerHub audible notifications for your home or business. Each YoLink app account includes 5 free SMS per month per device with the option to purchase additional SMS for a small fee. No subscriptions required, 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.
• 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.
• 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.
