I could swear I saw something about this last fall, but after searching here and on the ST forum, I am not finding it.
e.g. I want to turn a smart switch on in a completely separate ST account without needing to log into that other ST account in the Android app. Instead, I’d like to have a single instance of webCoRE connected to both, and do it from a piston.
Could someone please point me to whatever info there is available for this?
I found this, but I don’t totally understand…
The trick is you need a webCoRE instance for each hub…
(each device can only be directly controlled by one hub)
but…
Any piston on one hub can trigger any piston on the other hub by using the URL found here:
Pro Tip:
Make sure the URL points to a piston that has no triggers whatsoever.
Generally speaking, you want to see this up top:
Awesome!
Both instances of webCoRE (one in each of the ST systems) are already in place. So, this should be extremely simple now, compared to what I was imaging may be involved.
So, to specify a piston with a URL from the other instance…oh :nevermind: …I will just poke around.
If it’s where I think it is, I will be off and running shortly.
Thanks a lot for the assist! 
EDIT: I found it.
Location - Make web request.
I got it all set up, and it’s so cool!
Thanks again.
