• Each sensor has a maximum transmitting range in open air between the sensor(s) and the weather station.  
  • Consider what is in the signal path between the weather station and the
  • sensor(s).
  • Consider the distance the weather station is from other electronics in the home.


  • Obstacles such as walls, windows, stucco, concrete, and large metal objects can reduce the range.
  • When considering the distance between the sensor and the weather station cut that distance in half for each wall, window, tree, bush or other obstruction in the signal path.
  • Closer is better.
  • Do not mount the sensors on a metal fence. This significantly reduces the effective range.


  • Consider items in the signal path between the sensor(s) and the station.
  • Simple relocation of the sensors or the weather station may correct an interference issue.
  • Windows can reflect the radio signal.
  • Metal will absorb the RF (radio frequency) signal.
  • Stucco held to the wall by a metal mesh will cause interference.
  • Transmitting antennas from: ham radios, emergency dispatch centers, airports, military bases, etc. may cause interference.
  • Electrical wires, utilities, cables, etc. may create interference if too close.
  • Vegetation is full of moisture and reduces signal.
  • Dirt: Receiving a signal through a hill is difficult.
