14. Range
The range for radio signal transmission between the outdoor sensor and the weather station is up to 100 m at optimal
conditions.
However, the range values refer to the so-called „free field range“. This perfect alignment (e.g. weather
station and outdoor sensor on a smooth, level meadow without trees, houses, etc.), however, is never
present in practice.
Normally the weather station is set up in the house and the outdoor sensor is installed on or at a car port
or a garage.
Due to the different influences on radio transmission, no specific range can be guaranteed, unfortunately.
Usually, however, operation in a family home is possible without any problems.
When the weather station doesn’t receive any data from the outdoor sensor, reduce the distance between
the outdoor sensor and weather station, change the installation site or check the condition of the batteries
in the outdoor sensor.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass, aluminium windows, etc.
• Vehicles
• Trees, shrubbery, earth, rocks
• Proximity to metal & conductive objects (e.g. heater)
• Proximity to the human body
• Broadband interferences, e.g. in residential areas (DECT telephones, mobiles, radio-controlled headphones, radio-
controlled speakers, other radio-controlled weather stations, baby phones etc.)
• Proximity to electric motors, transformers, mains adapters
• Proximity to mains sockets, mains cables
• Proximity to badly shielded or openly operated computers or other electrical devices
