flash led on trigger or rule.

---

Would it be possible to control a led every time a action is performed ?
For instance when i click a button to toggle my light I would like to flash a led green so that I get visual feedback.
When I turn of the light I would like to see a red led flash.

The same applies to a rule set. So whenever a rule is triggered I would like to get notified visually.
Would this be possible by making a rule that says.
when $switch to on then toggle led green
when $switch to off then toggle led red

I hope I explained my self good enough to understand

with the gpio plugin you can control the raspi gpio’s. so if a led is connected you can use the gpio switch to simply switch on the connected led to the gpio in the gpioswitch device.
then you can use rules like “WHEN blah THEN switch on something and switch on gpiodevice for 1 second” or similar

Optionally you could write a script (.sh / .py) from where you control the color of an led (neopixel could od the job). You could even add patterns (blinking high speed/low speed) for various rules/events! (you can contact me for examples i use with Arduino && Neopixel)

@Stokstaart please share your example

@kolorek Have a look here , i wrote it a long time ago and it is bound to have faults/errors. But i think it could be a good startingpoint!!

In this case the Arduino i am commanding is connected to the Pi via USB cable (see neo.py for details… adjust where necessary!)
