Question about Device Interaction

I have heard that the device provisioning is done via port forwarding where to configure devices... you need to mess with your DNS?

How hard would it be to configure devices and a hub for someone who can't move well?

No port forwarding should ever be done with Hubitat. There is no need to configure DNS.

All device pairing and configuration is done via a local web site hosted off the Hubitat Elevation Hub.
