About this item

• AVOID USING WiFi FOR THIS! Our distinctive LoRa sensors stand apart from WiFi, Zigbee, Z-Wave, and the majority of other wireless smart devices because they offer exceptional long-range capabilities (up to 1/4 mile in unobstructed areas), low energy consumption (lasting years before needing new batteries), and are functional outdoors, across different levels of a building, and even within metal enclosures (such as refrigerators or mailboxes)!
• KNOW NOW! You have many options for being notified of device activity! Receive a text, receive an email, receive a phone push notification (including Apple phone "Critical Alert" severe weather/Amber alert type notifications that will activate your phone even if in silent mode. Android phones offer similar functionality, depending on phone manufacturer). SMS messages are limited to the total of 5 times each device plus 5. A hub and two temperature/humidity sensors provides you with 20 free SMS per month.
• ECONOMICAL SMART FRIDGE! Save thousands when you make ANY fridge smart (or smarter) with YoLink smart sensors. Start with temperature sensors, then add door/lid sensors, leak sensors and a Power Fail Alarm.
• THAT WAS EASY! Be up and running quickly with our SpeakerHub hot spot mode to join your WiFi network in moments. Add devices in seconds using our Scan & Play QR code scanner in the app! Set your notification preferences, test your new sensors, then enjoy years of trouble-free operation!
• TALK TO ME! Our unique SpeakerHub doesn't just play recorded messages and sounds, it tells you in clearly-spoken text-to-speech messages, AND plays attention-getting tones and sounds. You can even upload your own MP3 files, and hear your own sound effects and messages!
