than one second.
• The DCF reception is best at night, when there are least interferences by electronic devices (e.g. TVs or computers are off).
Just wait for the next day; the weather station should display the DCF time and date then.
• If you operate the outdoor sensor in a building for test purposes (e.g. at initial commissioning), place the outdoor sensor close to a window and as far away as possible from electronic devices, cables, power outlets, metal parts, etc.
15. Range
The range for radio signal transmission between the outdoor sensor and the weather station is up to 100 m under best conditions.
However, these 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 for, unfortunately.
Usually, however, any 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.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings
• Coated/metallised insulated glass, aluminium window frames, 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, radiocontrolled 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
