 We made the choice of retrieving from the html page rather than from a telnet session and the perl api of the fhem server simply because we were not really familiar with the entire API behind the FHEM server and the WEBFHEM was the tool that we understood most. We made the choice of retrieving from the html page rather than from a telnet session and the perl api of the fhem server simply because we were not really familiar with the entire API behind the FHEM server and the WEBFHEM was the tool that we understood most.

 +Among many classes used by our application we use three, that reflect real devices. Those classes implement the following methods:

 +Thermostat 
 +|_getDesiredTemperature() 
 +|_setTemperature(double Temperature) 
 +|_setScheduleTime(String dayTime, String time) 
 +|_getMeasuredTemperatures()

 +MovementDetector 
 +|_checkIfThereWasMovement() 
 +WindowDetector 
 +|_checkIfWindowIsOpened() 
 +</​code>​ 
 +\\ 
 +Class implementing our GUI creates new thread for movement detector and also for window detector. It checks the value returned by methods from suitable classes every given period of time.

 With the amount of time we had to work with the tools that were given, we decided to stick with the integrated schedule system of the fht80b thermostat. With the amount of time we had to work with the tools that were given, we decided to stick with the integrated schedule system of the fht80b thermostat.

 +Our system could also propose some changes of the schedule, based on the registered behaviors of the user, that differ from current schedule (for example lack of movement in apartment during the period, in which it should be heated). ​
