RF outlet library [solved]

Hi,

Can you please look at the attached pictures and recommend a RF Outlet Library that might work?
One thing I see is that there is no address switch or a label with the address and the libraries I know will not work.

Also I'm a bit concerned that, with no address, additional sets of outlets cannot be controlled independently.

If anyone is wondering, those are sold by Hornbach in Romania for around 10€.

Many thanks,
Adi





Can't read the text on the small chip, but have you tried this?

Using a "1pcs RF transmitter and receiver kit for Arduino project 433Mhz" from eBay you can try to listen to what the remote sends, and re-send that from the transmitter...

In case RC-Switch won't work, try this lib: homewatch/arduino/libraries/NewRemoteSwitch at master · hjgode/homewatch · GitHub

I used it to control sockets which also had "Turn off all" button.

Thanks to all for suggestions.
I found a working sample on https://sites.google.com/site/arduinohomeautomation/home/unitec_eim826 and I tuned the code with my DSO to the following:

const int outPin = 8;
//------------------------------------------------------------------------
// 1200bps=833us/bit lng=70%=583, sht=30%=250 , cor=correction for pinset/pinclear
#define FRAMEREPEAT 15
#define cor 4
#define lng 623 - cor//583 - cor
#define sht 208 - cor//250 - cor
// Macros for PWM bit pulse 
#define rfBIT_H  {digitalWrite(outPin, HIGH); delayMicroseconds(sht); digitalWrite(outPin, LOW ); delayMicroseconds(lng-5);}
#define rfBIT_L  {digitalWrite(outPin, HIGH); delayMicroseconds(lng); digitalWrite(outPin, LOW ); delayMicroseconds(sht-5);}
//------------------------------------------------------------------------
void setup()
{ pinMode(outPin, OUTPUT);
}//setup
//------------------------------------------------------------------------
void loop() 
{
  byte rfFrame = B00001;//Button 1 ON
//  byte rfFrame = B00011;//Button 1 OFF
//  byte rfFrame = B10001;//Button 2 ON
//  byte rfFrame = B10011;//Button 2 OFF
//  byte rfFrame = B01001;//Button 3 ON
//  byte rfFrame = B01011;//Button 3 OFF
//  byte rfFrame = B00101;//All      ON
//  byte rfFrame = B00111;//All      OFF
  for ( byte j=0;j<FRAMEREPEAT;j++)         // 15 Frame repeats
  {
    for ( byte i=0;i<20;i++) {rfBIT_H}                 // 20 preamble bits
    if (rfFrame & B00010000) {rfBIT_H} else {rfBIT_L}  // ChannelBit2
    if (rfFrame & B00001000) {rfBIT_H} else {rfBIT_L}  // ChannelBit1
    if (rfFrame & B00000100) {rfBIT_H} else {rfBIT_L}  // ChannelBit0
    if (rfFrame & B00000010) {rfBIT_H} else {rfBIT_L}  // On Off Bit
    if (rfFrame & B00000001) {rfBIT_H} else {rfBIT_H}  // stopbit always 1
                            
    delayMicroseconds(5647);//4600); // interFrame delay
  }//for j
  delay(1000); 
}//loop

/*

*/

Unfortunately the remote and the outlets don't have an address and additional sets will share the same RF commands.

Kind regards,
Adi
