Microsoft has released an update to Device Hub on the Windows Phone Store. The app enables you to connect to various accessories and configure said experiences. Unfortunately, Microsoft seemingly missed the memo about including changelogs with published releases, thus we're unaware of exactly what's new.
The app was last updated back in February. Give the update a download and let us know should you notice anything new.
