Found [here](https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=147781&start=75#p1005529) somebody that claims it should be possible, by adding a bitmask parameter to the command:

```auto
vcgencmd get_throttled 0x7

```

I understand this from his explanation:

- There are two persistent values stored in the Raspberry:
  - Value A: Keep track whether the Raspberry has been throttled since reboot.
  - Value B: Keep track whether the Raspberry has been since the bitmask has been used.

- You can get hold of both of these values:
  - Get value A by calling the command without bitmask.
  - Get value B by calling the command with bitmask.

If it works like this, then I think I should implement it in my node like this:

- Add a checkbox in my config screen "_reset throttling status at every measurement_".
- Apply the bitmask when the checkbox is selected.
- Add a warning in my readme file that only a single node-red-contrib-vcgencmd node is allowed to have this option. Indeed there is only 1 value B available in your Raspberry so the nodes would start resetting each others value B ...

Is there anybody that could check whether this theory is valid?  
Not sure how I could 'easily' throttle my Raspberry temporarily to experiment with this.
