Help with Variables Basics

[jim_]

trying understand how Variables work ... 

I can see the VAR_1 Init value change, but not control an actual device

 

I have 3 programs for this test

 

Variable ON

------------------

If

        X10 'B2/On (3)' is Received

 

Then

        $VAR_1 Init To 1

 

Else

   - No Actions - (To add one, press 'Action')

 

Variable OFF

------------------

If

        X10 'B2/Off (11)' is Received

 

Then

        $VAR_1 Init To 0

 

Else

   - No Actions - (To add one, press 'Action')

 

On the Variables TAB / State I can see the value in the Init column change to 0 or 1 when B2 goes On or Off

 

=======================================================================

 

What  I don't understand is why this does not work

 

Test device on / off via Variable

------------------

 

If

        $VAR_1 is 1

 

Then

        Set '25.C4.73.1' On

 

Else

        Set '25.C4.73.1' Off

Setting Init value is what the variable is set to when the ISY is booted.   Set the variable itself "Set $VAR_1 = 1" in addition to setting the Init value.

 

Then

        $VAR_1 Init To 1

        $VAR_1 = 1

 

 

Then

        $VAR_1 Init To 0

        $VAR_1 = 0

Also, to trigger on variable changes (when the value changes), the variable must be a 'state' variable.

Thank you for your help ... it works ...

Makes sense now  ... I wondered why Value on VAR_1 State never changed when Init was changing

Jim,

 

The Init of a variable is only referenced when the ISY boots.
