Get to Know YS8004 Weatherproof Temperature Sensor

Q: How do I set the high and low temperature and humidity ranges outside of which I would get a notification?
A: To set up temperature and humidity ranges for notification on the YoLink app, follow these steps:
1.Open the YoLink app and select the sensor device you want to set up.
2.Tap the three dots in the upper right corner to access the Details screen.
3.Tap Alert to go to the alert screen.
4.Set up the desired alert range for temperature and humidity (tap the pencil icon to set up the temp range easily).
5.Make sure the related strategy is enabled for app/email/SMS notification. To check the strategy settings, tap "View your alarm strategies" and select the related strategy.
6.Verify that YoLink app notifications are allowed in your phone settings, your email address is verified to receive email notifications, and your phone number is added to receive text message notifications. You can check your email and phone number settings in the YoLink app by tapping Menu (upper left) -> Settings -> Account.
Once you have set up the desired temperature and humidity ranges and notification settings, you will receive alerts if the sensor detects values outside of the specified range.
Q: Alexa only displays the temperature and not humidity. Additionally, it is not showing up as a trigger when setting up a routine. What should I do?
A: Unfortunately, the YoLink Temperature & Humidity Sensor is not currently supported to create routines in Alexa, and Alexa only displays the temperature reading from the sensor, not the humidity reading. Only the Echo's built-in temperature sensor supports routines.

If you want to use the sensor with routines, you can consider using IFTTT. IFTTT supports the Temperature & Humidity Sensor as a trigger action in routines. You can create an applet in IFTTT that triggers an action when the sensor detects a certain temperature or humidity range.

To get voice announcements from Alexa when the sensor alerts, you can use the VoiceMonkey skill. Here are the steps to set it up:

Enable the VoiceMonkey Skill in Alexa.
Sign in to the VoiceMonkey website using your Amazon Alexa account.
On the Manage Monkeys Page, add a monkey and name it as "Sunroom Monkey."
Create an applet on IFTTT app: if this - YoLink - THS - complete trigger fields, then that - Alexa Voice Monkey - choose Trigger Monkey(Routine) - select "Sunroom Monkey."
Set up a routine on Alexa, choose Smart Home, select "Sunroom Monkey," and add action.
Q: I purchased the temperature and humidity sensor, but for the last couple of hours, I have not received any readings. The chart drops to 0 degrees. Any ideas why I am missing readings?
A: Please check if your YoLink hub is online during that time. It might be possible that the hub is offline, and as a result, the data is not being reported to the server. The YS8006 X3 temperature and humidity sensor can save offline data and report it to the server when the device is back online.
Q: I am using YoLink sensors in a freezer, but the battery life is not accurately reported in cold temperatures. When I pulled the sensor out and let it sit on the counter for a while, it started reporting full battery life. Is it true that YoLink sensors last roughly 2 years or longer in extreme temperatures?
A: For YS8004, YS8005 and YS8006 temperature sensors, YoLink uses lithium batteries. Due to the characteristics of lithium batteries, the voltage fluctuates greatly in cold environments, which can cause the battery level to show low even if the battery capacity is actually high. However, the engineers have confirmed that this won't affect the actual battery life of the sensor. In extreme temperatures, the actual battery life of the sensor may last longer than what is shown in the app. They can help you update the firmware to 0409/0509 or newer, which optimizes the battery level display. Before updating the firmware, please place the sensor in a room-temperature environment. If the batteries do not return to full level after taking the sensor out of the freezer, please take out the batteries and measure the battery voltage, and feel free to contact YoLink support team.
Q: I need to replace the batteries in my YoLink thermometers. When they die, and I replace the battery, they never come back on again. How do I fix this?
A: Please try the following steps:

Remove the old batteries.
Press the button several times to discharge any capacitors.
Install brand new non-rechargeable batteries.
If this doesn't work, please contact YoLink support for further assistance.
Q: Is it normal for the temperature in a freezer to fluctuate by 10-15 degrees Fahrenheit in either direction?
A: Yes, it is normal for the temperature in a freezer to fluctuate by up to 10-15 degrees Fahrenheit in either direction. This is because the environment inside the freezer is not constant, and factors such as the frequency of opening the door, the amount of food stored inside, and the freezer's defrost cycle can all affect the temperature. Please set the appropriate alert range to avoid the false alarms.
Q: Is it possible to set a specific temperature for YoLink temperature and humidity sensors to trigger an alert?
A: In the YoLink App, you can set up alert ranges for temperature and humidity sensors, but you cannot set a specific temperature for the sensors to trigger an alert. Once you have set up the alert range, the app will notify you when the temperature or humidity is outside of the range you have set.
Q: Is a calibration certificate available for the YoLink sensor?
A: No, YoLink does not provide a certificate of calibration for its sensors, as they are fully calibrated at the factory and are guaranteed to be accurate without the need for additional calibration. Therefore, there is no calibration certificate available for the YoLink sensor.
For your reference, The YoLink temperature/humidity sensor uses very high-end digital sensors inside. (SENSIRION-SHTC3)
Q: What are some available Alexa commands for YoLink sensors?
A: One example of an Alexa command for YoLink sensors is to edit the name of the sensor in the Alexa app and then ask Alexa about the temperature. For instance, if you rename a sensor to "Pool" in the Alexa app, you can then ask Alexa, "Echo, what is the Pool temperature?" to receive the temperature reading from that sensor.
Q: How can I calibrate a YoLink temperature sensor?
A: If you believe that your YoLink temperature sensor is not very accurate, you can try calibrating it by comparing its readings to those of another accurate temperature-measuring device. However, it is difficult to determine which device is absolutely accurate. YoLink sensors are calibrated at the factory and are guaranteed to be accurate, they use SENSIRION chips.
Q: How can I change the temperature unit on Google Home from Celsius to Fahrenheit or vice versa?
A: To change the temperature unit on Google Home, follow these steps:

1.On the Google Home screen, tap "Settings".
2.Tap "Google Assistant".
3.Tap "Manage all assistant settings".
4.Scroll down to "Weather" and tap it.
5.Choose the temperature unit you prefer, either Celsius or Fahrenheit.
Q: One of my YoLink devices is constantly reporting a low temperature in the freezer, even though I don't care how cold it is. How can I stop receiving these alerts?
A: You can go to YoLink App->Sensor screen->Device Details screen->Alert to swipe to left to set up unlimited low-temperature alert, then you won't receive low temp alert.
Q: Why is there no log data available in the YoLink app?
A: If you are referring to the lack of log data in the app's History section, this is because the History tab only displays high/low temperature/humidity alerts. However, if you need access to more detailed sensor logs, you can tap the "More" button in the app to download a chart of the sensor data.
Q: I purchased the YoLink Weatherproof Temperature Sensor with Probe, but the 4ft probe length is too short. Can I splice in a longer cord or extend the cable? Is there a maximum length for the extension?
A: No, it is not possible to extend or splice a longer cord onto the YoLink Weatherproof Temperature Sensor with Probe.
Q: How can I use a smart relay in conjunction with a temperature and humidity sensor as a temperature controller using YoLink Control Tech?
A: To use YoLink Control Tech with a smart relay and temperature/humidity sensor, you'll need the YS8004-UC weatherproof temperature sensor, as it currently supports YoLink Control. When you receive the YS8004 sensor and YS5706 relay, contact YoLink customer support to update the firmware, as the necessary version isn't publicly released.

After updating the firmware, follow these steps to configure the temperature controller:
