We went under contract recently so am dealing with the same issue. As I hadn’t thought about future sales when initially starting, here’s what I had to do: Create a new email (housebame@gmail) for hubs and items such as ecobee, ring, etc. Begin excluding devices one by one so that they could be readded one by one after a factory reset on SmartThings. Once I added everything back in (about 40 items, including switches and hubs, etc), I recreated basic automations such as good morning, good night, I’m home, etc. I did not recreate some of my more complex automations as I have no idea if they have a similar schedule or needs as our family. I then put together a full packet that had a list of all items, including model numbers, PDF manuals of each item, and passwords for each account using the new email. Final transfer email outlines how to begin once they arrive and WiFi is installed (download these apps, and read these things, etc. I didn’t want a bunch of calls or emails with an upset new owner after close, so did all of the above. Took about 3. 5 hours all in. For our new home, I will be setting up under a house email from the start so as to avoid the extra work the next time we sell.
