Python or CMD/.bat to control PegasusAstro via Unity API?

[airscottdenning]

I am trying to write scripts to perform some basic tasks on my imaging equipment using the PegasusAstro Unity API. I found the API docs but have so far failed to get access to my Pegasus PowerBox Advance through Unity.

In particular, I'd like to be able to:
Check for dew conditions (relative humidity above a threshold)
Power off the PPBA at the end of the night if (and only if) the dew heater is no longer needed
Cycle power on camera or focuser (in case something won't connect)
Cycle USB3 Ports (in case something won't connect)

I see that Hans Kostense has published PyUPB to directly control the Pegasus Universal PowerBox, but I think that's the older (deprecated) API and won't work for PPBA anyway.

Does anybody know how to do this? Or better yet, can anybody provide example python or .bat scripts?

Many thanks!
Scott

Please help if you can.

I am trying to follow the methods in the PegasusAstro ApiDocs to communicate with my Pocket PowerBox Advance through the Unity server.

This is in Windows 11 with Unity Release Version : 1.10.1868.47.

I have no problem controlling the PPBA through the Unity app (or the legacy PPB.exe app). But I want to be able to script the PPBA. The documentation for the REST API seems fine, but I can't get a uniqueKey for my PPBA for some reason.

I can start the server from a CMD window with 'START C:\"Program Files (x86)"\"Pegasus Astro"\"Unity Platform"\server\Peg.Server.exe' and I can see server logs scrolling in a separate CMD window as I call the API using curl.

I'm certainly connecting to the server, and it's responding with JSON. But the data[] field in the JSON response is blank.

Without a uniqueKey I can't do anything to the PPBA.

Here's what I see using /Server/Start and /Reporting/Device:
