Beurer HM 55 Mode D'emploi page 14

As soon as the thermo hygrometer has been paired via the app,
the current time appears in the display. The time, temperature and
relative humidity then appear alternately in the display.
In the app, you have the possibility to specify minimum and maxi-
mum values for the temperature and air humidity. The LED indicator
on the device then shows whether the temperature/air humidity is
within (green) or outside (red) the set minimum/maximum values.
Due to its handy size, you can set up the thermo hygrometer almost
anywhere. There is also a mounting fixture on the back of the thermo
hygrometer that you can use to attach the device to the wall (e.g.
to a nail).
You can connect up to 5 thermo hygrometers at the same time using
the beurer "FreshRoom" app and give each of these a name (e.g.
"kitchen", or "living room").
