Hubitat control from another location

Can the HE be controlled from a remote location or must you be on the same WiFi system

Dashboards can be used remotely when not on the same wifi (if you allow/configure them to be). The new Hubitat phone app can connect to dashboards remotely as well.

Configuration of the system can not be done remotely, unless you connect back to your home network via a VPN (that would have to be setup external of Hubitat - it does not have a VPN server built into it).
