I recently moved, and did not start over from scratch, as I had most of the same rooms/sensors/setup. It went well! I added in new rooms and sensors as necessary. I did recently move from the Nortek combined stick to a separate SONOFF 3.0 for Zigbee and a Zooz 800 stick for Z-Wave, which also went well, but left things named a bit oddly. Reading some of the other comments about how often they blow out their environment makes me think maybe I should!
Which is somewhat BS, since we have a perfectly good Olympic Peninsula here in Washington State that it was certainly named after.
