What is Radio433

Radio433 is a device to receive multiples 433Mhz (or 315Mhz) types of radio communications.
Protocols managed: RemoteTransmitter (old)/NewRemoteTransmitter (new)/RadioHead (text)

Applications

Home Automation

Home Automation Example

• Control Cheap Power Outlets
• Control lamps
• Send text between arduino/raspberry pi

This technology (433Mhz) isn’t really reliable but this is pretty useful if you want to turn on/off power outlets remotely and cheaply.

Commands

• /info : Display name:port (radio433:42002)
• /status : Display status (in json)

  Receive radio

  The easiest way to get codes from power outlets is to use the remote provided with it

Data are received in JSON

{"data" : "/radio/text/Hello World"}

Send radio

send RadioHead code “Hello world”

/radio/text/Hello World

turn on new radio “address:1234 unit:1”

/radio/new/1234/1/on

turn off new radio “address:1234 unit:0”

/radio/new/1234/0/off

dim new radio to 8/16 “address:1234 unit:2”

/radio/new/1234/2/8

send old radio code “123456”

/radio/old/123456
