Adding tags to Ubidots devices is nothing new. But being able to filter what your end users can see, based on tags, is elevating user management to a whole new level.
You can now add tags to not just devices, but also dashboards, reports, events*, and end users. If there's a tag match between the end user, and any other entity, then it will be displayed to your end user.
