How to use ESP8266 on-board LED with ESPHome?

ESPHome
1

I built a BRUH multisensor a while ago with just the DHT22 and the AM312 PIR. I modified that Arduino code to light the on-board red LED when motion is detected. I’ve just made another such sensor with ESPHome (so easy, and it works great!) but I don’t know how to make the on-board LED light when the motion detector senses motion. Is this possible with ESPHome? Thanks for any help!

Yes it is.

You should be able to adapt the LED automation part of this video:

Thanks. I watched the video - now I have to study up on how to apply this to my situation :thinking:

Thanks to the video/documentation by JuanMTech, and the excellent documentation for ESPHome, I figured out how to turn on the on-board LED on my NodeMCU when the motion sensor detects motion, and turn it off when motion stops. I thought I’d post my code in case it can help someone else.
