Let me complete the example given for the node when you use V_IR_SEND.

In order to send IR codes you need to transform the
code in an unsigned long:

    char ircode[11] = {0};  // in case your code takes the form of 0xE0E0FF0F
    ...
    if (message.type == V_IR_SEND) {
      String hexstring = message.getString();
      hexstring.toCharArray(ircode, sizeof(ircode));
      ...
      // get the code as an unsigned long
      unsigned long code = strtoul(ircode, NULL, 0);

      // with IRLib send the code to TV
      sendSAMSUNG(code);
      ...

Very simple, ** but is hard to find an example**!

Hi,

Thanks for your promptly reply.

I have a node that acts like a IR remote to one of the newest Samsung TVs. This node runs a sketch that extracts IR codes from received messages and send them to TV and returns a feedback message to HASS. The node (with id 40) has a child sensor (with id 3) and his of type S_IR and accepts messages with type V_IR_SEND. In HASS this (ms)sensor is defined as a sensor (his identity_id is sensor.ir_remote) and displays the IR code that was sent, but there is no way in HASS to send a given IR code (for instance in automation) to this node... so a service to do that would be nice.
