This test took less than 10 minutes and worked flawlessly, as the Hub Replace test did but in less time!
I used a spare V3 hub that I had left over from my Hub Replace feature test. I factory reset it again just to make sure and added it back to SmartThings. Then, I pulled the power cable out of my Z-Wave hub and left it off for several hours. After that, I opened the SmartThings app and clicked on the V3 Z-Wave hub, which showed offline.
Then I clicked on the three dots and selected ‘Replace Hub.’
Next, I clicked ‘Replace this hub’ on the screen below.
The next screen showed ‘Original hub’ and ‘Replacement hub,’ along with the time of the last backup.
Then I got the same screen as in the Hub Replace test, and I scrolled all the way to the bottom.
Then I tapped on ‘Replace.’ I wasn’t as nervous this time since my Hub Replace test worked fine.
Then the process started; this took a little longer than the Hub Replace test, and I was a little nervous until I realized that the original device was offline now, and the process had to download the config from the SmartThings server. Transferring 51 of 51 devices.
Then the 20-minute message appeared again, waiting for devices to come back online.
When it finished it displayed the new Hub. Everything looking good.
This time, there was no waiting for devices to come back online; it was immediate.
Another plus for SmartThings: now there is an automatic backup of your SmartThings setup, and it works like a charm.
