[SOLVED]Variables as triggers


Question

I need help to understand why the below described HC2 Scene does not trigger when set to "Automatic" and the Variable "ATest" is set to "True". 

 

I can trigger the Scene manually wherafter the Device "Test" turns off as expected. Below follows the details:

 

In order to understand the difference between "Automatic" and "Manual" and the effect of having av Scene turned "On" or "Off" in HC2, I made the following very simple test Scene in the Graphic Block editor:

 

IF Variable "ATest" == "True"

THEN Device "Test" = "Turn Off"

 

The Variable "ATest" was created in the HC2 Variable Panel as a "Predefined Variable" with to defined values, namely "True" or "False".

The Device "Test" is a Fibaro Wallplug

 

In precise LUA code: 

--[[
%% properties
%% weather
%% events
%% globals
ATest
--]]

local startSource = fibaro:getSourceTrigger();
if (
 ( fibaro:getGlobalValue("ATest") == "True" )
or
startSource["type"] == "other"
)
then
    fibaro:call(182, "turnOff");
end

 

Any help to explain why the Scene does not turn off the device will be highly appreciated!

Hi @jodohl

 

When your scene is set to 'Automatic' then it will run whenever the following occurs:

  1. When the ATest global variable changes value (but not when changed via the Variables panel).
  2. You run it manually (eg: from the HC2 web portal or via the mobile app)
  3. The scene is run programatically from another scene, using the fibaro:startScene function (or equivalent in block scenes).

When it is set to 'Manual', then it will run when:

  1. You run it manually from the HC2 web portal or mobile app.
  2. The scene is run programatically from another scene.

So your scene will be triggered to run automatically in Automatic mode, but only when the ATest global variable is changed by another scene.

Thanks a lot, Dave! I had not noticed that changing value in the Value Panel will not trigger. Imporant to keep in mind:-)

In addition, the scene is not triggered if the variable is changed via the Fibaro REST API unless you also add the following in your json struct in the call: 

{
...
"invokeScenes":true,
...
}
