MClimate Vicki thermostat decoder

For who has interest, I have modified the downlink encoder from MClimate and also added all variables in the decoder.

In Node Red I have created a controller to control the valve to get the room to the desired temperature.

Currently I have set or scheduler in Node Red to change the desired temperature on the thermostat. My eventually goal is to integrate the thermostats in Home Assistant and to control the desired temperature from there.

function toBool(value) {
  return value == '1';
}

function roundToOne(num) {    
  return +(Math.round(num + "e+1")  + "e-1");
}

function Decoder(bytes, port) {

  var TYPE_keepAlive        = 0x01; // (9 bytes)
  var TYPE_hswVersion       = 0x04; // (3 bytes)
  var TYPE_keepAlivePeriod  = 0x12; // (2 bytes)
  var TYPE_openWindow       = 0x13; // (5 bytes)
  var TYPE_childLock        = 0x14; // (2 bytes)
  var TYPE_tempRange        = 0x15; // (3 bytes)
  var TYPE_tempAlgoPar      = 0x16; // (4 bytes)
  var TYPE_tempAlgoParTdiff = 0x17; // (3 bytes)
  var TYPE_operationMode    = 0x18; // (2 bytes)
  var TYPE_joinRetryPeriod  = 0x19; // (2 bytes)

Great, thank You! Would you be so kind and share configuration from NodeRED?
