I received this yesterday. I removed every non used or not needed Device Type and SmartApp and still 30 seconds to 1 minute to load on a high speed fiber line.
Thank you so much for letting us know about the slow load times in our IDE, and we’d like to apologize for this delay.
Regarding why your IDE runs a bit slower, it could be simply because you’ve got a lot of custom SmartApps and Device Handlers loaded up in your SmartThings account. Somewhere in there, whether its one of your customer SmartApps or Device Handlers, may be slowing down your “SmartApps” and “Device Handlers” tab load times. You may benefit from removing some of those items, and that would essentially quicken your load times.
Of course, I’ve made sure to forward this information to our development crew and if we see any trending issues with other customers, we’ll definitely get a hot fix applied.
If you need a custom device type how can they ask you to remove it. It has been on my IDE for over a year and never had a problem.
