Product Support

Your Temperature & Humidity Sensor connects to the internet via a YoLink hub (SpeakerHub or the original YoLink Hub), and it does not connect directly to your WiFi or local network. In order for remote access to the device from the app, and for full functionality, a hub is required. This guide assumes the YoLink app has been installed on your smartphone, and a YoLink hub is installed and online (or your location, apartment, condo, etcetera, is already served by a YoLink wireless network).

To provide years between battery changes, your sensor refreshes at least once an hour or more frequently if the SET button is pressed or if the temperature or humidity change meets refresh criteria as explained in the user guide.

Install the Temperature & Humidity Sensor

Environment Considerations:
Determine an appropriate location for your sensor.

Please note: the Temperature & Humidity Sensor is intended for indoor use, at dry locations. Refer to the product support page for the full environmental specifications.

• Consider our Weatherproof Temperature & Humidity Sensor for outdoor locations.
• If you plan to use this sensor in a freezer, ensure the sensor does not get wet during defrosting cycles.

Location Considerations:
If placing the sensor on a shelf or countertop, ensure it is a stable surface. If hanging or mounting the sensor on a wall, ensure the mounting method is secure, and the location does not subject the sensor to physical damage. The warranty does not cover physical damage.

• Do not place the sensor where it may get wet
• Do not place the sensor where it will be subjected to direct sunlight
• Avoid placing the sensor near HVAC grilles or diffusers

1. Before installing or placing your sensor, ensure the display mode is correct for your application. To switch between Celsius and Fahrenheit display mode, briefly press the SET button (on the rear of the sensor).
2. If placing the sensor on a shelf or countertop or other stable service, place the sensor where desired, then proceed to the next section.
3. Before mounting or hanging the sensor on the wall or vertical surface, determine your desired method:
   • Hang the sensor from a nail or screw or small hook
   • Hang or mount the sensor by other methods, such as 3M brand Command hooks
   • Secure the sensor to the wall using mounting tape, Velcro or similar methods. If affixing something to the rear of the sensor, be aware of the impact of covering the SET button or LED, and allow for battery replacement in the future.
4. Mount or hang the sensor on the wall or vertical surface using your desired method. (Insert a screw into the wall, hammer a nail into the wall, etc.)
5. Allow your sensor at least one hour to stabilize and report the correct temperature and humidity to the app. Refer to the full installation & user guide for instructions on calibrating your sensor, if it does not appear to indicate the correct temperature and/or humidity.

Refer to the full Installation & User Guide, to complete the setup of your Temperature & Humidity Sensor.
