Multiple feedbacks on 1 button

For the moment it is not possible to use several feedbacks on single item with native tools. But please use the attached JS sample. It makes you able to compare the list of feedbacks by OR and AND condition

Compare-Feedbacks-By-Or-Or-And-Condition.irpz

// compare feedbacks by logic OR

function Check_OR(_name, _buff, _token) {
   IR.AddListener(IR.EVENT_TAG_CHANGE , IR.GetDevice(_name), function(name,value) {
      var device = IR.GetDevice(_name);
      var summ = 0;
      for (var i = 0; i <= _buff.length - 1; i++) 
      {
         if(device.GetFeedback(_buff[i]) > 0)   IR.SetVariable("Global." + _token, 1);
         summ += device.GetFeedback(_buff[i])
         if (summ == 0) IR.SetVariable("Global." + _token, 0)
      }
   });
}

Check_OR("KNX", // Driver Name
        ["Dimmer", "Relay 2/30:Channel 11", "f32", "u32", "s32", "u16", "s16"], // List of Fb
        "Token_OR"); // Driver token where the result will be written

// compare feedbacks by logic AND

function Check_AND(_name, _buff, _token) {
   IR.AddListener(IR.EVENT_TAG_CHANGE , IR.GetDevice(_name), function(name,value) {
      var device = IR.GetDevice(_name);
      var summ = 0;
      for (var i = 0; i <= _buff.length - 1; i++) 
      {
         if(device.GetFeedback(_buff[i]) != 0)              summ += 1;
         if (summ == _buff.length)                          IR.SetVariable("Global." + _token, 1);
         if (i == _buff.length - 1 && summ != _buff.length) IR.SetVariable("Global." + _token, 0);
      }
   });
}

Check_AND("KNX", // Driver Name
         ["Dimmer", "Relay 2/30:Channel 11", "f32", "u32", "s32", "u16", "s16"], // List of Fb
         "Token_AND"); // Driver token where the result will be written

could/will this behaviour be added to native tool set?

you'll be able to use the logic blocks to do such sings. It is planned for release this year
