Node-Red Based Flex Microphone Level Meter and Level Gain Adjust

Using Node-Red, I built an integrated Flex Microphone Level Meter and Level Gain Adjustment. Details and downloads can be found on the Ham Radio Group IO site:

Here is a screenshot of a good Microphone level. The header background is green, and the value is the peak level selected. Peak is the significant microphone level in the last two seconds. You can also set the instant level or both. The "red tick" mark is peak level, and the bar graph is instant level.

Here the microphone level exceeds the high alarm, using peak value as the input:

The Flex Microphone Gain can be adjusted from the meter by sliding the "Black Tick." This makes it easy to adjust Flex Microphone gain while watching your actual microphone level. The slider is called from 0% to 100%, same as on Smart SDR:

If you are using a digital mode as the Flex Radio audio input, when TX DAX is "on," the meter background will be yellow. Here is a screenshot of me transmitting from WSJT-X:
