Trying to set global based on HA switch state

ESPHome
1

I’m building an indicator that sets a red, yellow, or green light to illuminate depending on the state of a distance sensor. I have that part working well, but what I’d like to do is to only enable the leds when the light to that room is on in Home Assistant so the leds aren’t on all day or night long when no one is there. Here’s my yaml where I’m having trouble getting the switch value from Home assistant, can anyone point me in the right direction to get this working? Thanks

So what are you seeing in the logs?

And why do you need a global? The state of the led_switch is known.

Thank you. I’m getting a compilation error on this line, but good point about not needing a global.
value: !lambda return id(led_switch).state;

In my first approach, I was trying to create a ‘virtual’ switch in the sketch and then having Home Assistant update that in the light switch automation.

That worked, Thank you @nickrout, I was making it needlessly complicated. Here’s the final yaml that worked for me.

Glad it worked, I am a believer in KISS and Occam’s Razor. :slight_smile:
