13. Range
The range for radio signal transmission between the outdoor sensor and the weather station is
up to 30 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.
Usually, the weather station is put up in the house, and the outdoor sensor to the side of a
window.
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. If the weather station
doesn't receive any data from the outdoor sensor (despite new batteries), reduce the distance
between the outdoor sensor and weather station, change the installation site.
The range may be considerably reduced by:
• Walls/masonry, 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 electrical motors, transformers, mains adapters, computers
• Proximity to mains sockets, mains cables
• Proximity to badly shielded or openly operated computers or other electrical devices
