5.3 Best Practices for Wireless Communication
Note: To insure proper communication, mount the remote sensor(s)
upright on a vertical surface, such as a wall. Do not lay the sensor flat.
Wireless communication is susceptible to interference, distance, walls
and metal barriers. We recommend the following best practices for
trouble free wireless communication.
Electro-Magnetic Interference (EMI) . Keep the console several feet
away from computer monitors and TVs.
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.
1. Line of Sight Rating. This device is rated at 300 feet line of
sight (no interference, barriers or walls) but typically you will get
100 feet maximum under most real-world installations, which
include passing through barriers or walls.
2. 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 obstruction decreases the transmission
range by the factor shown below.
