You can now check out Web App v9 on home.sense.com.
Changes in Web App v9 are all to the Settings page, accessed by clicking your account email address in the top right corner. There are a variety of visual design changes, but the main features added are the ability to change your username and password directly on the new Accounts page (found in the sidebar) as well as the ability to add and remove connected device integrations from the My Home page.
