4.3 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 com-
puter monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and commu-
nication is intermittent, try turning off these other devices for troubleshooting purposes.
You may need to relocate the transmitters or receivers to avoid intermittent communica-
tion.
3. Line of Sight Rating. This device is rated at 100 m line of sight (no interference, barri-
ers, or walls) but typically you will get 30 m 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” or ob-
struction decreases the transmission range by the factor shown below.
5.Final Installation of Sensors
Integrated outdoor transmitter installation.
Professional Wireless Weather Station can be used in both the Northern and Southern
Hemispheres.
Prior to installation, you will need to calibrate the wind direction.
5.1. Northern Hemispheres (NOR).
The cardinal directions (N, S, E, W) molded on the body of the outdoor sensor are indica-
tors for the Northern Hemisphere only.
Step 1: 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.
Step 2: Console operation is set to Northern Hemispheres (NOR in the time area) in Loca-
tion division.
