FRStackWeb Api Usage

I am running a Node-RED server and use FRStackWebApi to monitor the radio/client status for several years now. I have acquired another Flex radio and I was hoping some one that has used the FRStackWeb api and could provide insights on how they use the FRStackWeb Api for multiple radios. I have a need to show the status / environment for both radios simultaneously.

I have tried it using a single instance and also 2 instances of FRStackWebApi. I have not figured out how to isolate an instance to a radio. I have also not see much info on why you need to use multiple instances (possibly to control multiple slices).

At this point I am curious to why you would use multiple instances if you cant isolate an instance to a radio.

If anyone has used the api to see both radios on the network at the same time I appreciate your insights .

Thanks in advance
