YoLink Technology<br> "YoLink" is a proprietary wireless technology provided by YoSmart. which is based on the Semtech's LoRa wireless technology combined with the YoSmart smart home/building protocol, to provide the most advanced smart home/building devices solution. Compared to WIFI, Bluetooth, ZigBee, Z-Wave, and other smart home protocols, it has the advantages of low-power consumption, long-distance coverage (wall penetration), and anti-interference. It is the first smart building/home protocol that can be very easily setup and is a very low cost but creates a reliable, robust and more secure IoT network.<br><br> Requirements:<br> Smartphone or tablet running iOS 9 or higher, Android 4.4 or higher<br> <br> Specification:<br> YoLink Hub<br> Power: In-wall power adapter<br> Input: 5V DC<br> Maximum Current: 1A<br> Working Temperature: -20°C~50°C (-4°F~104°F)<br> Humidity: 0~90% non-condensing<br> <br> YoLink Temperature & Humidity Sensor<br> Voltage: 3V DC (2 - AAA batteries)<br> Alert Temperature: -22°F ~ +158°F, ±0.54°F (-30°C ~ +70°C, ±0.3°C)<br> Low Temperature Alert Default: 64°F (18°C)<br> High Temperature Alert Default: 95°F (35°C)<br> Alert Humidity: 0% ~ 100%, ±3%<br> Low Humidity Alert Default: 0%<br> High Humidity Alert Default: 100%<br> Working Temperature: +14°F~+122°F(-10°C~+50°C )<br> Working Humidity: ≤95% (non-condensing)<br> <br> Package List:<br> 1 x YoLink Hub<br> 2 x YoLink Temperature & Humidity Sensor<br> <br> Please Note:<br> YoLink Hub requires a 2.4 GHz Wi-Fi connection or a wired connection.<br> YoLink products work only in the USA and Canada.
World's Longest Wireless Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property.
Environment Monitoring – Be informed of the current temperature and humidity of critical equipment and rooms, as well as receive instant notifications of changes based on your personalized criteria. Current temperature and humidity is displayed on the YoLink app, along with historical graphs, so you can monitor current and past temperature and humidity conditions. Receive email and smartphone banner alerts per your individual settings whenever a pre-set value is reached.
Low-Power Means Longer Battery Life: Because of the low power consumption, device batteries may last 2 years or more (depending on application and device usage/activity), on standard AAA Alkaline batteries (lithium batteries not required)!
Team Me Up! – Pair your sensor with a YoLink Siren Alarm for immediate attention-getting alarms. Team your sensor up with one or more YoLink Smart Plugs / Smart Mini-Plugs, to do such things as turn on a dehumidifier upon high-humidity levels, or turn a bathroom exhaust fan on upon high temperature or humidity. Utilize the app’s user-friendly automation functions to create automatic actions per your specific needs. (Products sold separately!)
Plug, Plug & Play! Plug Hub into an outlet, plug Hub into your router, scan in new devices, and enjoy your new system, in minutes! Your Hub is the only device that connects to the Internet, and a wired or WiFi connection is required (wired required for easy & fast Plug, Plug & Play, and most reliable and secure connection). WiFi connection set-up difficulty varies and requires changing settings to your network and/or your phone Changes to your network, passcodes, etc, require changes in the app.
