I am not sure where to post this. But when I log into https://graph-na02-useast1.api.smartthings.com/ide/apps I can see all my apps and devices. But when I log into https://graph.api.smartthings.com/ I have no devices or anything. What is going on here?
You need to know the SHARD that your Location is hosted on. It is very important!
This method works:
You can “accidentally” create your own custom Device Type Handlers and SmartApps on any SHARD and that would be a mistake, because then you can’t “publish for myself” and install into your Location.
Therefore, until further notice from SmartThings, know your SHARD URL and always login explicitly to it!!!
