7. Best Practices for Wireless Communication
Note: To ensure 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 433MHz devices and
communication is intermittent, try turning these other devices off for
troubleshooting purposes. You may need to relocate the transmitters or
receivers to avoid intermittent communication.
3. Line of Sight Rating. This device can reach 100 metres in line of sight (with
no interference, barriers, or walls) but typically you will get 30 metres 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 walls. If you have metal walls, align the remote and console
through a window to get a clear line of sight.
