Hi
I am creating a flow which turn off screen when power source is plugged or unplugged. But the condition is that it should not turn off screen when display is already on.

But i am facing some problem.
Screen on condition is not working.
Please help...

Hi,

Does the condition work when you open the condition and select Menu->Execute? The condition should show a notification on screen with the text Condition ended with 'True'.

Perhaps your device turns the screen on immediately when the power source is connected so the flow is executed too late and condition Screen On already evaluates to true.

In this case you would have to use a trigger Display State: On, store the time in a variable and check in the power connected/disconnected trigger whether the screen was turned on very recently.
Something like this:

Flow1
-trigger Display State: On
-action Script: global_last_screen_on_time = triggertime;

Flow2
-trigger Power Source: Connected
-action Sleep: 1s. Ensures that Flow1 had a chance to completely execute
-condition Expression: triggertime - global_screen_on_time < 2000. Checks if the screen was turned on within the last two seconds (2000ms).
-->true: -action Lock Device
-->false: -action Notification on Screen: Display was already turned on before

Regards,
Martin

Sorry, my mistake. The global variable in the second flow should have the same name as the one in the first flow.
Please change the condition in the second flow to:
-condition Expression: triggertime - global_last_screen_on_time < 2000

Hi Martin

Thanx again for your reply but my flow again ended with an error.

It looks like there's a space in your variable name after the text global_. Please remove the space and try again.

Thanx martin for your help and for your wonderful app!!
