Can I control a relay on MagicMirror2?

[shbatm]

You may want to take a look at the MMM-PIR-Sensor module and see if you can adapt it for your needs. It includes the ability to control a relay for turning on/off the monitor.

@shbatm Thank you.
Can I use a bulb instead of a monitor?

Yes. I saw. But I make to turn on & turn off a bulb on MagicMirror2.
I use to voice control used ‘annyang API’.
If I say " Turn on the light.", a bulb will turn on.
I think to make a new module about voice and relay control, right?
But It is very difficult…

@MaengMarco Check the voice control software you’re going to use… I’m sure they have some sort of instructions on how to…

Using WebIOPI is simple way to control GPIOs . The followings is my solution.

1. To install WebIOPI to your raspberry Pi.
   webiopi Installation
   Note: if you use webiopi 0.7 and rasp 2, you have to run the patch.

2. In the node_help.js of your module, use ‘http post’ to control the GPIOs.
   WebIOPI rest api
   ex:
   SET ‘GPIO 3’ to ‘IN’ , the request as below:
   HTTP POST
   http:/192.168.1.200:8000/GPIO/3/function/in
