strange return value

[geo903]

Hello! Thank you so much for your development!
I use an example of your code to get the value of the boiler modulation and get a strange value, if it is divided by 256 then do not get a number from 0 to 100%

  unsigned int data = 0xFFFF;
  unsigned long request = ot.buildRequest(
  OpenThermRequestType::READ,
  OpenThermMessageID::RelModLevel,
  data);
  Serial.println("mod:"+String(ot.sendRequest(request)));

Central Heating: on
Hot Water: off
Flame: off
diagnost: 0
fault: 0
**mod:3222339584**
Boiler temperature is 36.80 degrees C

Hi @geo903 ,
To get modulation level you have to parse response like this:
float modulation_level = (response & 0xFFFF) / 256.0;

Thank you! it works!
