- Q: How secure is your system?
A: YoLink takes security very seriously and has implemented multiple measures to ensure the security of our system, including:
1. Utilizing AWS security systems and encrypted network communication to defend against malicious attacks;
2. Conducting regular security audits to detect and respond to potential hacker attacks;
3. Implementing secondary encryption for each communication of the device and dynamically encrypting each piece of data. Each device has a unique encryption key that varies with network access. Even if a hacker attacks our network, they cannot directly control your device. - Q: Do I need to pay for the YoLink Cloud services? Will it always be available?
A: No, the YoLink cloud service is free and you have unlimited app push message notifications for YoLink system alerts. - Q: Do YoLink devices work globally?
A: Yes, YoLink products work globally anywhere as long as there is an internet connection to the hub and your phone. However, it's important to note that different countries have varying wireless product regulations. YoLink products have received FCC certifications that meet the standards of the US and Canada, and some products meet UK certifications. YoLink is officially allowed to sell products in the US, Canada, and UK, but the products can work all over the world. It's worth noting that YoLink Plug Series only works with 100-120V currently. - Q: Can you provide definitive information on how often each YoLink device communicates with the Hub to report its status?
A: YoLink devices are classified into three types: Class A, Class C, and Class D. Most battery-powered devices are Class A, such as door and leak sensors. They send a signal to the Hub when an event occurs and transmit a status update to the cloud every 4 hours. Class C devices, such as energy plugs, are externally powered and always in receive mode. They send status updates to the cloud every 30 minutes. Class D devices, like valve controllers, can be powered by a battery and external power simultaneously. They are always in receive mode and send status updates to the cloud every 4 hours. - Q: Will the YoLink Control (D2D pairing) between the devices be lost when the batteries are changed?
A: No, the YoLink Control (D2D pairing) between the devices will not be lost when the batteries are changed. You do not need to be concerned about it. -
Q: Is there a web-based app for YoLink?
A: Currently, YoLink does not have a web-based app. However, you can use the BlueStacks emulator to install the YoLink app on your PC. The Raedius console is only available for commercial use. YoLink plans to develop a PC app in the future. - Q: I can’t get my YoLink device online, should I purchase a hub?
A: In order to get your device online, you need to connect your device to a hub.
Please kindly note, the YoLink Hub acts as the central controller for the rest of the YoLink devices, it is required to use YoLink devices.
As you may know, YoLink smart devices use a special wireless technology based on LoRa, which can offer extreme long range (1000 feet compared to 100 for WiFi, outdoors, line-of-sight) and superior obstruction penetration including concrete and metal, but they do not use your WiFi. They need to wirelessly connect to one of our hubs.
YoLink Hub connects YoLink devices to the internet and the cloud, the integration with YoLink system and 3rd parties works through the cloud. One YoLink Hub supports more than 200 YoLink devices in real test.
You can purchase a hub from the following link.

https://www.amazon.com/dp/B09FSS95G9 - Q: Does D2D affect notifications? I set up D2D and app push, but when I test the sensor, the valve shut off and I did not receive app notification. What's the issue?
A: When testing the water sensors, if you are using your fingers to trigger the sensor, please do not remove your fingers from the probe immediately. This is because if you have set up D2D, it will prioritize the D2D notification over the app push notification. Therefore, if you quickly remove your fingers, the D2D notification may be triggered but the app push notification may not have enough time to be sent. To ensure both notifications are received, it is recommended to wait a few seconds after triggering the sensor before removing your fingers. - Q: Could the YoLink Control prevent me from receiving alerts?
A: YoLink Control and alerts can work simultaneously, but if the hub is offline, you will not receive any alerts. Additionally, when testing a water sensor, please ensure that the sensor is submerged in water for at least 5 seconds, as YoLink Control will execute first and then the system will send alerts. - Q: Do you have a forum?
A: YoLink has a Discord Power User Group. To join, please contact YoLink customer service by sending an email to service@yosmart.com with the subject line "Discord Group." They will then send you an invitation link. -
Q: I have noticed that there are instances where devices are paired to each other directly instead of through the normal connection process via scan and bind. What is the difference between the two methods, and will the devices still work together and send local notifications if the Wi-Fi is down?
A: The direct pairing method is called YoLink Control or D2D, which is a unique technology of YoLink system. It can work without an internet connection, but the functions such as automation and notifications in the app require an internet connection. For example, you can set up YoLink Control between a water leak sensor and a valve controller, so that when the sensor detects water, the valve will close automatically without the need for internet. However, you will not receive notifications without an internet connection. Additionally, you can set up automations in the app, such as closing the valve when water is detected, but this will not work without an internet connection. - Q: Why can't I use rechargeable batteries for YoLink devices?
A: YoLink devices use non-rechargeable batteries only because of the method of measuring battery capacity based on voltage. The voltage of rechargeable batteries fluctuates greatly, making it difficult to accurately measure battery capacity. - Q: Why UC and EC products can not work together?
A: Due to varying information security policies in different countries, US version and European version devices cannot be used together in the same scene or automation. UC devices can only connect to the UC hub, not the EC hub. However, by switching servers in the YoLink app, you can set up different automations for your US and EU devices separately. It's important to note that scenes and automations specific to the US area cannot be accessed when in the EU area. To switch between service areas, simply go to the YoLink app, click on the menu icon (three lines in the upper left-hand corner), select Settings, and then choose your desired service area.
