General Questions

I have a specific question about a product. 

Please visit our product support page and look for the specific product, and user guides and manuals for that specific product will be on that page. 

Do YoLink devices work globally?

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.

What Ethernet ports do YoLink Hubs utilize?

RJ45 Ethernet Cable.

Can you provide information on how often each YoLink device communicates with the Hub to report its status?

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.

Will the YoLink Control (D2D pairing) between the devices be lost when the batteries are changed?

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.

Is there a web-based app for YoLink?

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 web console is only available for commercial use. YoLink plans to develop a PC app in the future.

I can’t get my YoLink device online, should I purchase a hub?

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.

Hub

Speakerhub

Do I need to pay for the YoLink Cloud services? Will it always be available?

No, the YoLink cloud service is free and you have unlimited app push message notifications for YoLink system alerts.

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?

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.

Could the YoLink Control prevent me from receiving alerts?

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.

What ports do the hubs use?

For ports 8001-8002, the traffic is TCP only.

How secure is your system? 

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.

Do you have a forum?

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.

Why can't I use rechargeable batteries for YoLink devices?

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.

Why is it that UC and EC products can not work together?

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.

How can the traditional water meter be reset to zero, excluding the Yolink Smart Water Meter (YS5007)?

The water meters offered by Yolink are mechanical in nature. To reset the meter to zero, one must utilize a blower to blow back towards the water outlet.

What is the designated water temperature range for the YoLink mechanical water meter?

The designated water temperature range for the mechanical water meter spans from 5℃ to 30℃.

What is the purpose of the black cap on the Yolink mechanical water meter?

This component is employed to fine-tune the metering accuracy during calibration. By rotating it, users can adjust the performance either positively or negatively. This feature is specific to externally adjustable multi-flow water meters. The black cap is sealed to prevent user tampering.

Why is there a significant variance between the temperature readings from my Yolink temperature sensor and the ambient temperature?

The internal temperature sensor of the Yolink temperature sensor devices is exceptionally sensitive, resulting in disparities in temperature measurements influenced by external environmental factors like wind or dew.

To delve deeper into this matter and ensure the reliable operation of the Yolink temperature sensor, we suggest conducting a comparative assessment with another model we offer. Place both sensors in the same location and allow them to stabilize for one to two hours. If the final temperature readings from both devices correspond closely, it indicates proper functioning of the Yolink temperature sensor. Any observed temperature differences could then be attributed to environmental conditions.

I positioned a temperature sensor inside the freezer. What causes it to register an unusual temperature spike at a specific time each day?

Some freezers may undergo brief temperature variations as part of their regular functioning, leading to occasional alerts. This phenomenon appears to coincide with the defrost cycle of the freezer.

I'm attempting to install the latest firmware for my device, but it seems to be stuck at 100%. Should I be concerned?

If the screen shows the word 'Green' after completion, it indicates a successful update. The 100% indicator will vanish after a few minutes, as it's simply a temporary display during the upgrade process.

How do I turn two exterior alarms on at the same time?

You may use scene features or automation through the YoLink app.

I'm interested in receiving alerts specifically for water leaks with my water leak products, without being bothered by notifications when the device is offline. How can I configure this?

  1. Go to the alarm strategy page.
  2. Edit an existing alarm strategy.
  3. Select the device associated with the water leak detection.
  4. Customize the alarm settings for your sensors accordingly.

Disabling the default alarm strategy will solely deactivate the offline alert, leaving your water leak alerts unaffected.

Why is SMS messaging limited in YoLink?

Text messages sent from our platform to customers' phones are not without cost; in fact, they incur a substantial expense, particularly when usage crosses into the tens of thousands.

We take pride in offering competitively priced, top-quality smart home products. In addition, our commitment extends to providing uninterrupted and excellent service. While we will continue to ensure that emails and App push notifications remain complimentary throughout the lifetime, the SMS service has proven to be an escalating financial burden, reaching thousands of dollars each month and showing no signs of slowing down. Customer accounts are automatically given a limited number of free SMS messages per month, based on the number of registered devices (one account has 5 default quotas and one device has 5 free quotas).

A handful of our customers activate the SMS service across all their devices, thereby incurring significant costs for each customer, upwards of $20 monthly per device. To sustain the viability of YoLink and its progression, we find ourselves in the position of needing to request that our customers exercise restraint in their use of SMS, reserving it solely for significant events like water leak detection and security alarms.
Our unwavering commitment is to present unparalleled products at unbeatable prices, complemented by exceptional support in the realm of smart home technology. However, due to the substantial operational outlay associated with SMS services and the necessity to provide consistently dependable service to all users, we are compelled to adjust our approach to SMS notifications.



Consequently, we have formulated a plan to furnish a predetermined allocation of complimentary SMS messages per month to every customer account, based on the count of registered devices. Upon reaching this threshold, the feature will experience limitations, and we recommend utilizing SMS only when truly necessary. As a further step, unlimited SMS services will now be exclusively extended to our subscription-based clientele.

Why does my device show offline?

If your YoLink smart device shows as "offline," if you have a hub, don't worry, it is still functional. The only device that connects to the internet is the Hub; all other devices connect to the Hub through a digital handshake. To conserve energy, these devices only send signals to the Hub intermittently, with different spacing intervals depending on the device. For example, a water leak sensor sends a signal to the Hub every 4 hours, while a smart plug sends a signal every half hour. When the devices detect any status changes, they immediately send signals to the Hub. The "offline" status only means that the Hub was not connected to the internet at that time. In reality, these sensors and plugs never directly connect to the internet. The devices will automatically reconnect to the Hub within 4 hours, but they will reconnect immediately if there are any status changes. Alternatively, you can press the set/power button on the device to connect it to the Hub immediately. If you take out the batteries of sensor, it won't alert you immediately, but it will send an offline alert within 8-12 hours.

 How can I invite a member to my YoLink account and set up notifications for them?

To invite a member to your YoLink account, they must first sign up for their own YoLink account and verify their email address through the YoLink app's Settings. Once they have done this, you can log in to your account and go to Menu -> My Home -> Home Users -> Invite User to invite the member. You can share an invitation code, which they can paste into their phone's browser, or send a QR code for them to scan within the YoLink app. After the invitation is complete, you can set up related notifications to All under Menu -> Settings -> Alarm Strategies -> In Strategies Settings. Additionally, you can set up different permissions for the member under Menu -> My Home -> Permissions and choose their permission level by swiping left under Home Users.

I am trying to log in to the YoLink App, but it says my username or password is incorrect. What should I do?

Are you using your website credentials to log in to the YoLink App? If so, please note that you need to sign up for a separate account within the YoLink App. The website and app do not share login credentials, so you must create a new account within the app to access its features.

Can you explain the terms in YoLink's Advanced Settings of Automation?

The terms in YoLink's Advanced Settings of Automation are as follows:



Save execution log: Enabling this option allows you to check the automation history.

Retry when action fails: If this option is enabled and a behavior fails, the automation will retry that behavior (1 to 3 times).

Continue if action fails: Enabling this option allows the automation to proceed to the next behavior if a behavior fails. If it is disabled, the automation will be aborted if the behavior fails.

Notify me if action fails: This option sends you a notification if a behavior fails.

Interval of continuous execution: This option allows you to set a time interval (e.g., 1 hour) for an automation. For example, if you set up an automation to start a siren alarm when a door is opened, and the interval is set to 1 hour, the automation will only execute once per hour, even if the door is opened multiple times within that hour.

How can I move devices from Home A to Home B on YoLink?

To move your devices to another home on YoLink, you need to follow these steps:

1. Delete the devices in the first home by going to the device details screen (tap the three dots in the upper right corner on the device screen), scrolling down, and selecting "Delete Device."

2. Switch to the second home by going to YoLink App -> Menu -> My Home -> Switch to another home.

3. Scan the QR code to add the devices to the second home. You can save the QR code on the device details screen so that you don't have to go to the installation location to scan the actual devices.

How do I arm or disarm my YoLink system?

You can set up two scenes to arm or disarm your system. Here are the steps:

Armed scene: Add behavior -> Choose alarm strategy -> Select the strategy related to your door sensor -> Choose advanced settings -> Set notifications to Admin, All, or None (if desired) -> Select "Siren Alarm" in the Trigger Action area -> Save.

Disarmed scene: Add behavior -> Choose alarm strategy -> Select the strategy related to your door sensor -> Choose advanced settings -> Set notifications to Admin, All, or None (if desired) -> Deselect "Siren Alarm" in the Trigger Action area -> Save.

Once you execute the armed scene, a door open will trigger a siren to start an alarm. If you execute the disarmed scene, the door open will not trigger a siren.

Can I update the firmware of all devices with one simple button at the same time?

 Currently, one hub can support updating the firmware of up to four devices at the same time. However, it is recommended to update the firmware of devices one by one to avoid a slow and potentially high failure rate.

Can one YoLink device be added to multiple accounts?

No, YoLink devices can only be bound to one account at a time. However, you can invite others as members of your account to share access to the device.

I am receiving an error message ""device cannot be bound"" while trying to add a device, what should I do?

If you encounter the "device cannot be bound" error, please contact YoLink support and provide them with the device's SN number (located at the bottom of the QR code) or the EUI number on the scanning screen in the app. YoLink support will assist you in resolving the issue by obtaining the necessary device information.

I got a new phone and cannot access my YoLink account as I don't remember my username. What should I do?

If you have forgotten your YoLink account username, you can contact (https://shop.yosmart.com/pages/contact-us-page) YoLink support and provide them with your associated email address, phone number or the SN number of your hub. They will send you your username so that you can reset your password and regain access to your account.

If I have to uninstall/reinstall the app or move it to another device, will I lose everything?

No, you will not lose any data. All your data is saved on our encrypted cloud server. Whether you use a new hub or phone or reinstall the app, your settings will remain intact.

I've noticed that the app has been running slower over the past few days. Can you help me fix the problem?

If you are experiencing slow loading times in the app, please try force closing the app and restarting it to see if that resolves the issue. It's also important to ensure that your app version is up to date. The app screen operates similar to a web page and may need to be refreshed if it has been open for an extended period of time. Additionally, if the app has been running in the background for an extended period of time or if you have many apps open at once, the app process may be terminated due to limited RAM.

How to delete my account so I can start over with my system?

Please go to YoLink app->Menu(3 bars in upper left)->Settings->Account->Advanced Settings->Delete Account

 When I remove the batteries from a YoLink sensor, it still shows as "normal" in the app. What is the reason for this?

YoLink devices only send signals to the Hub at specific intervals to save energy, and the interval varies by device type. For example, the water leak sensor sends a signal to the Hub every 4 hours, while the smart plug sends a signal every half hour. If there are no changes detected, the device will not send a signal until the next interval. Therefore, when you remove the batteries from a sensor, the Hub may not receive the notification immediately, but within 2 to 3 intervals (8-12 hours), it will receive the notification and alert you.

Can you add multiple triggers to the automation in the app?

Yes, currently, you can use the filter function in the Smart section->Automation->Then behavior to create more complex automations.

When I attempt to update the firmware on a sensor, there is no indication of a firmware update.

For sensors, the firmware update will not occur immediately after confirming the update in the app. It can take up to four hours to complete. Alternatively, you can manually trigger the update by pressing the "set" button on the sensor.

When updating the firmware, it freezes at 0.2% and exits. What can I do?

Please follow these steps to troubleshoot:

1. Remove the batteries from the device.

2. Press the SET button on the device five times.

3. Reinstall the batteries.

4. Attempt the firmware update again.

I ran a diagnosis test, but I didn't receive a text message, and both the siren and speaker hub didn't sound an alarm. What's going on?

The diagnosis test only checks the app and email notifications. It doesn't send a test SMS code or trigger the siren alarm or speaker hub. If you want to test the devices, you can simulate an event and see if the system responds accordingly.

If you have more than one home property, can both properties be added to one YoLink account?

Yes, you can add multiple homes to one YoLink account, but you will need an additional YoLink hub for the second property. However, please note that if you create two homes on the YoLink app, Alexa/IFTTT/Google will only recognize the main home.

Once I set up the scene in the YoLink app, Alexa doesn't update immediately.

Please try Alexa app -> "Add" -> "Device"  ->  "Other" -> "Can't find a matching logo" -> "Not Sure"

Is there a feature on Alexa where I can say for example, ”Alexa, disarm pantry door”

The YoLink door sensor can interact with Alexa in two specific ways:

  1. Alexa Routine Trigger: The YoLink door sensor can be used to trigger Alexa routines based on its status (Open or Close). For example, you can set up a routine in the Alexa app where if the YoLink door sensor detects that a door is opened, it can trigger other smart devices or services. This could include turning on lights, playing music, or sending a notification to your phone.
  2. Voice Query for Status: You can ask Alexa about the status of your YoLink door sensor by using a voice command. For instance, you can say, "Hey Alexa, what is the status of [name of the door sensor]?" Alexa will respond with the current status of the sensor, such as whether the connected door is open or closed.

Because of this, you can enable or disable Alexa routines using voice commands. To do this, simply say "Alexa, enable [routine name]" or "Alexa, disable [routine name]" to your Alexa-enabled device. This command will activate or deactivate the specified routine. 

Is there a way to use Alexa to arm or disarm the YoLink system with voice commands?

Yes, you can set up a routine in Alexa to trigger a scene in YoLink. First, make sure you have discovered the new scene in the Alexa app. Then, set up a routine, selecting "when this happens". Choose "voice" as the trigger, and then set the phrase you want to use to arm or disarm the system. For example, you could say "Echo, arm my home". Then, add the action "Smart Home", select "Control scene", and choose the scene you want to execute. Finally, save the routine and you'll be able to use your voice to control your YoLink system.

How can I add geofencing to the YoLink system?

Unfortunately, YoLink does not currently support geofencing. However, you can use the IFTTT app to integrate geofencing with the YoLink app. To set it up, download the IFTTT app and follow these steps:

1. Create a new applet and select "If This"

2. Search for "Location" and select the trigger for entering or exiting a designated area

3. Select "Then That" and search for YoLink, then choose the action to execute a scene.

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.

 I was told that the YoLink skill is not available in Brazil for Alexa. What should I do?

To use the YoLink skill with Alexa, you can try changing the region of your Amazon account to the United States. Please follow this link for instructions: https://www.amazon.com/gp/help/customer/display.html?nodeId=201248840. Alternatively, you can create a new Amazon account with a US region setting to use the YoLink skill with Alexa.

I can't seem to get IFTTT and YoLink to talk to each other. I have a YoSmart account, but whenever I attempt to authenticate through YoSmart Auth, I get an error message "Account info not match,Login failed."

Please remember to use your account username, not your email address. It's important to ensure both your password and username are accurately entered.

What are the limitations on UAC API access?

To prevent excessive usage and ensure fair access for all users, the UAC API imposes restrictions on individual API users in two primary ways:

2. Within a 1-minute sliding window, a single target device can receive no more than 6 API calls, with a minimum interval of 200 milliseconds between each call.

Why is the 'Http Callback' feature unavailable?

The UAC does not support http callback functionality.

Regarding the access_token message, how frequently should I obtain it?

Do YoLink sensors work with standard LoRaWAN gateways?

Due to security concerns, YoLink sensors are not supported for use with other quasi-LoRaWAN gateways.

I'm curious about the potential launch of products that will be compatible with Local API in the future. Will current devices be updated to support Local API, or will I need to buy new Hub and sensor units?

The upcoming product lineup for this year (2024) includes a Hub that is designed to work with Local API. Additionally, other Lora terminal devices can also utilize Local API functionality through this Hub.

I am trying to use the API to open and close a valve, but fail to authorize it every time. The response is: {"state":"error","msg":"Auth Failed”}

Check whether there are special characters in the value of client_secret. If there are special characters, the parameter value needs to be url_encoded. Or submit using json.
