I'm building a power relay controller based on RPi and I want to be able to turn my whole system off by asking Alexa to shut it down.
I have considered using an Alexa-controlled "smart" relay to short the GPIO pins that send a shutdown command, but it would be simpler if I can launch a shutdown command/script/task on the Pi itself through an Alexa voice command.
Note: I'm not asking about the Alexa voice control libraries running on a Pi, I have external Echo devices that I would be talking to. The Pi in question will be connected to the Internet (or at least my home network) for monitoring/control purposes.
