5.3 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We
recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer
monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and communication
is intermittent, try turning off these other devices for troubleshooting purposes. You may need to
relocate the transmitters or receivers to avoid intermittent communication.
3. Line of Sight Rating. This device is rated at 300feet line of sight (no interference, barriers or
walls) but typically you will get 100feet maximum under most real-world installations, which
include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If
you have metal siding, align the remote and console through a window to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each "wall"orobstruction
decreases the transmission range by the factor shown below.
Medium
Glass (untreated)
Plastics
Wood

6 Final Sensor Installation
6.1 Anemometer Installation
Prior to installation, you will need to calibrate the wind direction. There is a "S" indicator on the
wind vane that indicates South, as shown in Figure 13. Align this "S" marker in the direction of
South.
