<p>Thanks! I confirmed that there isn't such a G-code.
I sent a pull request to make this posible:

<p>Now, "M80 S" reports the current state of the power supply.</p>

<p>I'm using <code>M80</code> and <code>M81</code> G-codes to power on/off power supply. </p>

<p>Is there a G-code to know the actual state of the power supply?</p>

While there is no dedicated command for this, there may be some options.  Can you describe your hardware?
Are you using a stock printer or a custom?
What are you turning off with the M81?
Are you just turning off the 12V and leaving 5V board supply on?
What boardset are you running?  RAMPS?

(Asked by: username_0 on 2017-05-09)

I'm using `M80` and `M81` G-codes to power on/off power supply.

Is there a G-code to know the actual state of the power supply?

I don't see one at <http://reprap.org/wiki/G-code> so it's probably safest to set the power supply to the state you want.
