Quite frequently interferences are only of a temporary
nature and may be easily overcome. If there are
wireless headsets, remote babysitters or other devices
working on 433MHz in your house or in the vicinity,
their switch-on time is mostly limited. Furthermore most
of these devices allow the change to an interference-
free frequency. Such measures will effectively
overcome interferences.

Transmission Range
The transmission distance from the thermo-hygro sensor to
the base station in open space under optimum conditions is
330ft. Although the signal transmission may travel though
solid surfaces or objects, the following points should be
avoided if possible:
-
High frequency interferences of any kind.
-
High densities of trees.
-
Broadband interferences in municipal areas can reach
levels reducing the signal/noise ratio over the entire
frequency band, thus also reducing the transmission
distance.
-
Devices working close by (example a neighbor’s house)
may also influence reception.
-
Poorly shielded PCs can cause interferences that will
reduce or in some cases stop reception
-
The transmitter and receiver should not be mounted on
metal surfaces as this will reduce transmission range.

Cleaning and Maintenance
-
Clean the housing and screen of the base station only
with a soft damp cloth. Do not use abrasives or
solvents.
-
Ensure that the rain sensor does not collect leaves or
other dirt by checking the funnel for blockages every
now and then. Also clean the seesaw of the sensor with
a damp cloth and check by lightly tapping with your
finger that it can move freely from side to side.
