[APP][Pro] Connect Solar Goodwe Inverter to Homey

@Wes_Holsteyn Here’s how to find it manually:

  1. Log in at semsplus.goodwe.com
  2. Click into your station (Station List → your station → Station Details)
  3. Look at your browser’s address bar. The URL looks like:
    https://semsplus.goodwe.com/#/station_monitor/station_detail?eyJzdGF0aW9uaWQiOiI...
  4. Copy everything after station_detail?
  5. Go to any free base64-decode tool (e.g. base64decode.org), paste that string, and decode it
  6. You’ll get something like {"stationid":"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx","appType":"WEB"} — the stationid value (the UUID) is what the app’s manual station-ID field wants

I’m also working on a fix so the app finds this automatically for more accounts instead of requiring this at all — will update here.
