Re: SPE Linear V1.1 flow uploaded to files section

 

Frank,

2 thoughts come to mind:

1) The 2K is the only unit with a combiner and lower unit. Any unit other than the 2K will not report data for those gauges.
2) I updated the comments in the initialization node to clarify what and how the unit setting works.?
See if this helps. If not, let me know.

/*
The SPE can be set to display temperature in Celsius or Fahrenheit. Data
returned from the SPE via the serial USB interface are unit-less and
there is no way for Node Red to determine the temperature unit selected.

The unit (C or F) selected in the SPE Node Red flow must match the units (C or F)
selected on the SPE setup menu on the amplifier itself.

For Those that would like to display units in degrees Fahrenheit, ensure the SPE
is configured to report temperature in F, comment out the first line (Celsius)
and uncomment out the second line (Fahrenheit).

The purpose of the selection below is to 1) display "C" or "F" on the gauges and
2) set appropriate min, seg1, seg2 and max limits for the gauges.

The flow always reports the numeric temperature provided by the SPE with no
conversion (C to F or F to C) on the temperature itself.

Hi Ron;

I'm new to Node Red, and learning quickly (drinking from the fire hose, as it were).? As a means of jumping in with both feet, I installed your SPE Linear flow as the beginning of a Dashboard that I'm building for my station.? I'm running Node Red on a Pi 4B (2GB), and your flow started working as soon as I configured it, which is great, but I do have one minor issue.

Everything seems to work except the temp gauges.? I initially commented out the Centigrade line and un-commented the Fahrenheit line in the initialization node, but that didn't work at all ¡ª the gauges all still showed ranges of 25 to 65, and none of them showed any reading.? I then restored the default for Centigrade in the Initialization node, but now I see no reading on the Temp (Lower) and Temp (Combiner) gauges, and a reading of 73 (which seems more like Fahrenheit than Celsius) on Temp (Upper).

Have you seen anything like this before?? Any suggestions on how I should debug this?

?

Thanks es 73,
Frank N6OI
