Rebooting hub for remote administration

I'm interested in setting up a remote administration subscription. I have 3 hubs registered to my account. One hub is remote in AZ that I won't have access to until Aug. The other two are local.

My question is if I need to physically reboot each hub in my account for them to get added?

Thanks

Usually not.. As long as you can see them on my.hubitat.com you’re fine.
