Just an update as I have received my SwitchBot Hub Mini & Smart Meter Plus and easily configured them first in the SwitchBot App and then integrated with SmartThings. Thank you for all the help & advice from the members of this forum!
One issue I have observed is that I have the temperature units configured for Celsius in the SwitchBot app, and I am pretty sure it initially showed up as such in SmartThings, but then a few hours later I noticed it was showing in Fahrenheit. I messed around with some config settings in SmartThings and could not find a temperature units setting, and then mysteriously this morning it was back to C. Taking a quick look at some other postings such as this one, it seems there have been previously reported issues. I also checked my Samsung account profile and it already had my country set as Canada (hence celsius) but I added some detail and saved my profile, so that may have had an impact but if it did, it was not immediate.
