@kacper_zet Try moving this code from receive to void loop and add a check to see if the status has changed from it's last state. Maybe then it will work for you.
digitalWrite(message.getSensor()-1+RELAY_PIN, message.getBool()?RELAY_ON:RELAY_OFF);
// Store state in eeprom
//saveState(message.getSensor(), message.getBool());
// Write some debug info
Serial.print("Incoming change for sensor:");
Serial.print(message.getSensor());
Serial.print(", New status: ");
Serial.println(message.getBool());
If not then it might be HA relsted and I can't help with that.
