Car heater timer

[Erik Trapp]

Hi!

I'm trying to figure out how to make a departure timer to control a wall socket for my car heater.

I have a working system with 4 sliders to set start and stop hour and minute but the goal is to only set the desired departure time (hour and minute) and then have openremote to calculate when to switch on the socket based on outside temperature.

What I am trying to achieve is if the outside temperature is above 0°C then the heater should start one hour before the set departure time.

Between 0 and -5°C, 1,5 hours before departure time.

Between -5 and -10°C, 2 hours before dt.

Below -10°C, 3 hours before the set departure time.

This is an example how I use the temp sensor i other rules: 

  CustomState( source == "oregon1temp", eval(Float.parseFloat((String)value) < -5.0 ))

Have any of you guys any suggestions on how I can solve this?

This is how the timer is configured at the moment:

rule "Start car heater"
when
  CustomState( source == "GVMonSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "1" ) ||
  CustomState( source == "GVTueSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "2" ) ||
  CustomState( source == "GVWedSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "3" ) ||
  CustomState( source == "GVThuSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "4" ) ||
  CustomState( source == "GVFriSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "5" ) ||
  CustomState( source == "GVSatSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "6" ) ||
  CustomState( source == "GVSunSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "7" )
  CustomState( source == "GVActivateTimer1Status", value == "on" )
  Event( source == "TimeSweHour", $htime1:value )
  Event( source == "GVStartTimeHour1", value == $htime1 )
  Event( source == "TimeSweMinute", $mtime1:value )
  Event( source == "GVStartTimeMinute1", value == $mtime1 )
then
  execute.command( "Garage Socket(ON)" );
end


rule "Stop car heater"
when
  CustomState( source == "GVMonSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "1" ) ||
  CustomState( source == "GVTueSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "2" ) ||
  CustomState( source == "GVWedSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "3" ) ||
  CustomState( source == "GVThuSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "4" ) ||
  CustomState( source == "GVFriSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "5" ) ||
  CustomState( source == "GVSatSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "6" ) ||
  CustomState( source == "GVSunSwitchStatus", value == "on" ) && Event( source == "Weekday", value == "7" )
  CustomState( source == "GVActivateTimer1Status", value == "on" )
  Event( source == "TimeSweHour", $htime2:value )
  Event( source == "GVStopTimeHour1", value == $htime2 )
  Event( source == "TimeSweMinute", $mtime2:value )
  Event( source == "GVStopTimeMinute1", value == $mtime2 )
then
  execute.command( "Garage Socket(OFF)" );
end

Hi Erik,

a similar problem was presented in my retrofit airco project. There was a cooling problem but it can easily be adopted to the adoptive heating.

Kind regards,

Hi Michal,

I try to use some parts from your air-conditioning code just to set the time but I have stuck and only get this error message:

ERROR 2016-10-23 15:00:52,511 : Rule definition 'CarHeater.drl' could not be deployed. See errors below.

ERROR 2016-10-23 15:00:52,512 : Rule Compilation error The method _ShiftTime(String, int) is undefined for the type Rule_CarHeaterTimeInc1227608620

This is the rule so far:

then

  execute.command($s,"OFF");

end

rule "CarHeaterTimeInc"

  timer(int:300ms) // debounce & protect double click

when

  Event(source == "GVCHTime", $v: value)

  Event($s:source == "CHTime.inc" , value == "ON")

then

  execute.command($s,"OFF");

  execute.command("GVCHTime", _ShiftTime($v.toString(), 5));

end

rule "CarHeaterTimeDec"

  timer(int:300ms)

when

  Event(source == "GVCHTime", $v: value)

  Event($s:source == "CHTime.dec" , value == "ON")

then

  execute.command($s,"OFF");

  execute.command("GVCHTime", _ShiftTime($v.toString(), -5));

end

Hi,

probably some functions are missed. Simply copy it to the rule's file:

function String _ShiftTime(Object o, int min){

  String mt = o.toString();

  if(mt.equals("")){mt="-";}

  SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");

  Date date = null;

  if(mt.substring(0,1).equals("-")){

    date = new Date();

    date.setTime(date.getTime()+60*60000);

  }else{

    date = sdf.parse(mt);

    date.setTime(date.getTime()+min*60000);

  }

  return(sdf.format(date));

}
