Node-Red Based, Flex Signal Strength Meter

Using Node-Red, I built an integrated Flex Slice Signal Strength Meter. Details and downloads can be found on the Ham Radio Group IO site:

Here is a screenshot of the meters. I have a 6600, so, four slices:

There is a Pull-Down selector to select what is displayed on the gauge header:

There is a Pull-Down Selector to select the display and squelch source, either the instant signal strength or the peak signal strength (peak over the last five-second window). The red "tick bar" on the gauge shows the peak receive level:

Mute and Squelch mode is selected from a Pull Down. The meter background color is yellow: mute on, and black: mute off:

The Squelch threshold is set by clicking on the gauge and is indicated by the red bar in the header. Squelch source is either the instant receive level or the peak receive level (I like using the peak level for squelch control):

The gauge header will show when the Flex is in MOX:

If a Flex Slice is not open, the Slice Status will be shown in the gauge header:
