@Heyqqqq You can disable the LED via the iOS app (for some reason it's still not available on the Android app). Otherwise, you can use the Node-RED plugin node-red-contrib-tplink or the underlying package https://github.com/plasticrake/tplink-smarthome-api. If using the latter, you could do something like:

const { Client } = require('tplink-smarthome-api');

const client = new Client();
const plug = client.getDevice({host: '10.0.1.2'}).then((device)=> {
  device.setLedState(false);
});

@Joshman08  The light isn't really that bright and it seems like you are just trying to cause problems. This switch is awesome and easy to install. There is a reason it is almost 5 stars on Amazon with over 6000 reviews. So get off her and quit being a troll. 

@TomR22 The older model HS200s have a light that is blindingly bright. My HS220s are much more subdued, though (and probably the newer HS200s). In any case, this is especially frustrating given it's a feature that is already built into the switch and already available on the iOS app, but is still not available for Android (about 75% of all mobile phones).

For those without an Apple Device, but have a Linux/Windows box that can run Python, there is a Python command line app that you can run to turn the light on/off.

An example to turn it off:
./kasa --host 192.168.1.65 led 0

An example to turn it on:
./kasa --host 192.168.1.65 led 1

I had to use this myself tonight, as I installed a couple switches into bedrooms today, and forgot about the LED until my wife and son complained... :)
 

I would like the ability to control when the led light is on. I'm using it to switch coach lights on or off. For me it would be useful if the LED was on when the lights are on and off when they are off, but for other applications the opposite might be more beneficial, so you can see the switch in the dark. 
 

I agree being able to dim or schedule the LED on or off time could also provide nice flexibility. 
 

@Casey69 Here is a video on how to turn it off: https://youtu.be/7CWBOeSN4yo

Sure! But I think that it will be needed to disassemble it

@Cambucha no need to dissamble. https://www.youtube.com/watch?v=7CWBOeSN4yo&feature=youtu.be
