Currently its not possible to Authorize 2 Hubitat locations in SharpTools. You can only have one hub at a time. Note that these locations are on different LAN’s so Hub Mesh will not work. Hubitat returns a token which is valid for a single hub at a time.
Solution - Workaround:
Add capability in SharpTools to store a token per hub allowing for multiple Authorized Hubitat locations in a SharpTools account.
