SendRawData does not take effect for Eurotronic Spirit Z Temperature

Hi,

for some time now I've been playing around with the Eurotronic Spirit Z Thermostat in order to set the measured temperature from an external sensor.

At first parameter 8 of the thermostat has to be set to 0x80 what I did.

After that I tried the following script to change the measured temperature of the device to 12 °C. The expectation was, that the valve opens since the setpoint was set to 19.5°C.

Unfortunately I wasn't able to recognize any success.

var OZW = require('./lib/openzwave-shared.js');
const Buffer = require('buffer').Buffer;

var zwave = new OZW({
    Logging: true,     // enable file logging (OZWLog.txt)
    ConsoleOutput: true // enable console logging
});

zwave.connect('/dev/ttyACM0');

zwave.on('scan complete', function(){
        console.log('Buffer will be written now............................');
        const buffer1 = Buffer.from([
                                         0x31           // COMMAND_CLASS_SENSOR_MULTILEVEL
                                        ,0x05           // SENSOR_MULTILEVEL_REPORT
                                        ,0x01           // Sensor type: TEMPERATURE
                                        ,0x42           // 0010 0010: 001=Decimal  - 00=Celsius - 010=2 Byte
                                        ,0x04,0xB0      // 0AF0 --> 2800 --> 28.00°C.04B0 --> 12°C.
                                        ]);
        console.log('sendRawData will be run now...........................');
        zwave.sendRawData(
                        6                       //nodeID
                        ,'sendTemperature:'     //logText
                        ,49                     //Sensor Multilevel Command Class 0x31
                        ,false                  //sendSecure
                        ,buffer1                //content
                        ,6                      //length bei > 5 ermittelt das Modul automatisch die Length
                        );
        console.log('sendRawData run completed.............................')

        setTimeout(function(){
          console.log('Start to disconnect now............................');
          zwave.disconnect('dev/ttyACM0');
          console.log('ZWAVE disconnect has been run......................')
        }, 15000);
});

The following log was printed related to the SendRawData:

ZWAVE disconnect has been run......................

Of course I've scanned a lot of different forums(e.g. iobroker, fhem, zwave, various github repos, ...) to gather any information that might help. Related to the output above I've just found, that the termostat won't respond to the command in any case.

Has anybody an idea why the sendRawData function does not work? How can the command be changed to not expect any response from the device?
