Wondering is it is possible to have two separate lines on the home page to see both the blower and servo output, maybe with the servo showing 0 to 100 speed and a red line showing the limit speed set point ?
You can use the Custom CSS functionality to separate the two bars, #fanc (the total PID/servo output) and #fanf (the blower output). Setting "position: relative" on both will make them show up one after the other. You'll probably need to enlarge the #fancontainer as well so they'll fit.
However you can not show the blower limit because that's not available in the "status update" data provided.
