Distance/Resistance/Interference

Distance:

• 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.

Resistance:

• 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.

Interference:

• 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.
