Mark, MKCM Software, has an excellent Readme documenting all aspects of using FRStack on Raspberry Pis (32 and 64), Macs and Linux machines.
He has details for all the installs of Dot.Net, Node-Red, and FRStack. ?Also, details on the FRStack Configuration file (UDP broadcasts for meters and N1MM formatted packets, default settings, and Com settings for PG-XL and SPE amps)
And a list of all of the REST commands for controlling your Flex, Your PG-XL, and SPE amp. ?He recently added GPIO relay controls. ? Use these commands to build Node-Red flows and to build custom buttons on your StreamDeck Device.
