Earlier this week my V3 Samsung branded hub failed. The power supply was putting out 0 volts so I got a replacement, but the hub was DEAD.
So I ordered the same hub as a replacement, added it to my home, and DID NOT MAKE A HUB PAIR even though setup hit me with a huge prompt to do so.
Once the new hub was added I went to the settings of the failed hub and saw the Replace Hub option had appeared. My understanding is the prompt only appears when you add a new hub that is available as a replacement.
I selected the Replace Hub, clicked through the screens, and after 3-5 minutes everything was active on the new hub.
It took another 5-10 minutes for all the devices to become live on the new hub.
After that everything just…worked. Like, perfectly. I didn’t have to do anything, troubleshoot anything, reboot anything, rewrite any routines, reestablish any integrations. Nothing, nada.
Based on years and years of dealing with home automation and integration I figured this would be an hours long process followed by days/weeks/months of troubleshooting, ghosts in the machine, etc.
Nope, it just worked as expected. Bravo to whomever did the Replace Hub work, it was easy and flawless for me.
