This project extends the RCSwitch library to support the Chacon 54662 power outlet sockets, and provides a simple program to send binary codes. It has only been tested on a Raspberry Pi.

To compile this program, make sure you have built and installed the WiringPi library first.

Then execute make in the code directory and you should obtain the send program.

The send.sh wrapper script makes use of flock to prevent concurrent calls using a file lock.

Connect a 433MHz transmitter to the GPIO pin of your choice on a Raspberry Pi (see the pin numbering documentation).

Then execute ./send.sh <gpio pin> <code word> [repeat count] where the code word is a 24-bit binary code (see protocol and samples below).

For example: ./send.sh 0 010111110010101011100011 3

The following information has been deduced from captures of an original remote control, and may not be 100% correct. See the RCSwitch Add New Remote tutorial for more information.

The Chacon 54662 protocol as emitted by the original remote control is made of:

• 4 frames encoded with "A" timings
• 4 frames encoded with "B" timings

Each frame starts with a sync bit followed by 24 bits:

• 4 bits static code 0101
• 16 bits rotating code
• 4 bits socket code

Rotating codes likely depend on the remote control (see samples below), and each button has 4 rotating codes. Codes are reused between buttons/states:

• A/ON = C/OFF
• B/ON = D/OFF
• C/ON = A/OFF
• D/ON = B/OFF

Socket codes:

• A: 0011
• B: 1010
• C: 0001
• D: 1000

Timings observed during capture, in microseconds:

The following codes have been captured from an original remote:

For example, use:

• /send.sh 0 010111110010101011100011 to simulate Button A ON
• /send.sh 0 010101100000010001000011 to simulate Button A OFF
