If not connected to the internet, over 64,000 events are stored in the sensor for later uploading to the cloud. *Additional features added with future device updates.
• POPULAR APPLICATIONS include fridge, freezer and cooler, greenhouse and grow room temperature & humidity monitoring. View current and historical temperature/humidity activity from the app. Receive notifications in the form of SMS, email, and phone push (including Critical Alerts - iOS only). With optional products not included, receive spoken and tone alert notifications from a SpeakerHub, or single-tone alerts from one of our indoor or outdoor sirens.
• NO WIFI WORRIES! 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.
• 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! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
