Introduction
B
YoLink X3 Temperature Humidity Sensor is a thermometer
and hygrometer. With monitoring the real-time
temperature and humidity levels in your home, it can
provide you with an early warning if temperature or
humidity is out of the comfortable range, the sensor will
blink red once, and notifications will be sent to you.
Please also note, your smart X3 Temperature Humidity
Sensor connects to the internet via one of our hubs
(original YoLink Hub or the SpeakerHub), 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. Otherwise, your X3
Temperature Humidity Sensor will have limited
functionality with no remote access. Please contact us for
additional information on this topic.
The original YoLink Hub or the SpeakerHub is
required for full functionality.
If the sensor is connected to the hub, once it is offline(do
not repower the device), it can record and save the offline
data in the device itself, according to the recording interval
(refer to page11) you set up in the app. If the recording
interval is 1 minute, the device can record and save 30 days
offline data. When the sensor is back online (connect to the
hub, and the hub connects to the Internet), it will report the
offline data to the server.
