WIRELESS 433 MHz WEATHER STATION Instructions Manual INTRODUCTION: Congratulations on purchasing this Weather Station with wireless 433 MHz transmission of outdoor temperature and display of indoor temperature and humidity, weather forecast icons and weather tendency indicators. It is further featuring a DCF-77 radio controlled clock with.
rc-switch has built-in functions that sends codewords for certain natively supported devices – so If you have one of these devices (I don’t) you may be able to skip this step.
Open the rc-switch “ReceiveDemo_Advanced” example sketch. Upload it and open the serial monitor. Hold your remote near your receiver module and press a button. The Arduino should decode the signal and print the results in the serial monitor. This is what I got for my remote-controlled mains switch when I press the button to turn channel 5 on:
The LX2262A-R4 uses a 12 tri-state bit codeword comprising 8 address bits followed by 4 data bits. For the tri-state codeword above – 011000001000 - the address is 01100000 (channel 5) and the data/command is 1000 (turn on).
My mains switches can have up to 8 addresses with a separate on and off command for each. By pressing every button and decoding the signals I worked out the codes for all the addresses and commands:
![]() ![]()
I suspect the address codewords will be the same for all devices of the same make & model – if anyone can confirm this please let me know.
The EV1527 chipset in my garage door remote uses a 24-bit codeword comprising 20 address bits followed by 4 data bits. The codes I got from my garage door remote are:
