I created a combination of them.

It is intended to attach on the right side of my Anet A8

Now you have a enclosure to control the printer via Octopi and a four channel relay, and you can read the power consumption.

powermeter:

I am using two relays of the board to switch both power lines
the other two relais I am using to switch two different LEDs

Wiring should be clear, if not don't do it ;-) at least its your risk.

I had to modify my config.yaml for octoprint:

system:
actions:
- action: printer on
command: gpio write 21 0; gpio write 22 0
name: Druckerin an
- action: printer off
command: gpio write 21 1; gpio write 22 1
name: Druckerin aus
- action: Licht an
command: gpio write 09 0
name: Licht an
- action: Licht aus
command: gpio write 09 1
name: Licht aus
- action: Drucklicht an
command: gpio write 08 0
name: Drucklicht an
- action: Drucklicht aus
command: gpio write 08 1
