SequenceEvents

Stacking events

You can set MH to do a sequence of events from one command as follows.

For example when one command is received (ie. Testlight ON) it will turn lamp module D1 off for 1 second, then ON for 20 minutes, dim to 60% for one minute, then off.

You have an X10 switch addressed A1 code my $watch_A1 = new X10_Item("A1"); my $control_D1 = new X10_Item("D1");

if (state_now $watch_A1 eq ON) {

    # First, turn OFF for 1 second and then ON
    $control_D1->set_with_timer(OFF, 1, ON);

    # Next, schedule a timer to run in 20 minutes. When it runs, turn light to 60% and then turn it OFF 60 seconds later
    my $dim_timer = new Timer();

    set $dim_timer 20*60, '$control_D1->set_with_timer("60%", 60, OFF)';

} code You can also stack the states with delays all in one go, like this: code $watch_A1 = new X10_Item("A1"); $control_D1 = new X10_Item("D1");

set $control_D1 'OFF~1~ON~20~60%~60~OFF' if state_now $watch_A1; code

if you just want a sequence without the delays use : so you might have 'on~1~off:on:off:on:off' but the device might not be able to handle data this quick.

• • Notes:**
• set_with_timer only does two events.
• It works for X10 devices but not serial.
• Because some code uses ~ eg in file abbreviation thus C:\progr~1\winamp.exe and elsewhere the timer feature is disabled in some Items from version 2.80. However it can be reactivated.

There is a Generic_Item states_overload method, which is set to 'off' in Socket_Item, Serial_Item, and xAP_Items.pm. To enable the timed sequences turn it on thus: code $control_D2 = new Serial_Item(undef, undef, 'serial_test1' ); $control_D2 -> state_overload(ON); code But then the ability to turn it off again is not in code below 2.88

To fix this, add this elseif clause in lib/Generic_Item.pm: code sub state_overload {

  my ($self, $flag) = @_;
  if (lc $flag eq 'off') {
    $self->{states_nomultistate} = 1;
    $self->{states_nosubstate} = 1;
  }
  elsif (lc $flag eq 'on') {
    $self->{states_nomultistate} = 0;
    $self->{states_nosubstate} = 0;
  }

} code
