I’d recommend giving this a bit more time, @oasis. I know that’s not the first thing you want to hear, but Sense needs more than two weeks of data to identify the devices in your home.
Here is a good post from the Community taking a look at some of the reasons why we don’t “train” Sense, as you suggested. Our data science team is constantly working to improve our device detection algorithms based on the data we have been receiving from users like you. As time progresses and more Sense monitors come online, the device detection will continue to improve.
While you’re waiting for Sense to model your home energy usage and devices, there’s still a lot you can do through the Power Meter in the meantime to ensure you’re hitting your goals. That link provides a walk-through of how to use the Power Meter to reduce your Always On bubble and minimize energy vampires and large energy loads.
If you have any other questions about some things you can use Sense for while it’s actively building out your home energy models, please reach out. Our Community loves helping new users and we have some amazing content I can share with you in the meantime.
