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.
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 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.
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 obstruction decreases the transmission range by the factor shown
below.
