Help with power conditioned scene

Plugins & Plugin Development Program Logic (PLEG)
1

Hi guys. A bit new on PLEG usage. Reading through various posts and basics guide all should be clear and I should be able to create simple scene.

I am trying to enable automated LED on behind tv screen during night time watching. I put in condition of TV setup plug power usage, if its above 90 wats LEDs should go on, is its below 80 watts it should switch off.

I do get them to turn on but they don’t turn off automatically. What I am missing? Status snapshot below.

It looks as though your are confusing Sequence expressions with Logical ones. Sequence expressions are concerned only with times. Local expressions care about states. I also think you have your comparisons backwards.

First add a Trigger that reflects the state of your TV LED switch - called, say, tvledison. Then change your Conditions as below:

Conditions
tvledon No night and (tvpower > 90)
tvledoff No tvledison and (tvpower < 80)

This helped. Now works as it should.
Thanks for help Rex. I am learning still with these things but getting there :).
