I bought my v1 hub over 3 years ago, and I have over 30 devices connected to it. I am still using the SmartThings (classic!) iOS app to regularly control the devices. Thus far, there are no pressing reasons to force me to upgrade to a newer version of the hub. However, I am curious as to any pros and cons of upgrading to v3.
For one, do I need to use the new Samsung Smartthings iOS app if I upgrade to v3? Second, can both v1 and v3 hub co-exist for a short period of time while I migrate devices over to the v3 hub? Third, is there even an easy migration path from v1 to v3 besides me adding back all the devices manually?
So far, the only compelling reason I can think of in upgrading is that v3 would have support for the latest protocols and I don’t want to be left behind, but I would love to hear from folks who have gone through the process to let me know any gotchas.
