Okay, here we go.

First, a bit of background on how to use the API to switch talkgroups.  Basically, you construct a web address with the following structure:

http://tgif.network:5040/api/sessions/update/(your hotspot dmr ID)/(timeslot)/(talkgroup you want to switch the hotspot to)

For example, say my hotspot ID is 311164401, on timeslot 1, and I want to switch it to talkgroup 31665.  My web address would be:

http://tgif.network:5040/api/sessions/update/311164401/1/31665

To send a 4000 disconnect, it would be:

http://tgif.network:5040/api/sessions/update/311164401/1/4000

So, you plunk the appropriately formed address into your browser, hit "go," and voila: You're controlling your hotspot (or hotspots).   I have bookmarks in my browser to send each of my hotspots to the talkgroups I frequent.  And, in Firefox, you can open multiple bookmarks at the same time.  So, I can switch all my hotspots at the same time with a single click. 

Issue a 4000 disconnect to everything? Done.  Set my TGIF Spot to 31665, my Jumbo Spot to 777 scan, and my DVSwitch installation to the Trivia Net on 147435? Done.

Of course, the same caveat applies to doing this as self-care: Your browser must be behind the same IP as the hotspot (or spots) you're trying to control.  But self-care does NOT have to be operational for this to work.
