4.3.1 Best Practices for Wireless Communication

Note: To insure proper communication, mount the remote sensor 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.
