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 tempera-
ture or humidity change meets refresh
criteria as explained in the user guide.
