dek8ce, we definitely want users to be involved in the device detection process. I assure you that ego is not a factor! If we felt that manual training would a good use of your time, we would work on implementing it (see: http://blog.sense.com/articles/training-sense/ for more information).
That being said, we are looking for ways to have users involved in the device detection process. For example, we recently added the ability to let us know when a ‘Device is not on’. If you see a device on when it shouldn’t be, you can mark it as such (in the device details screen under ‘Report a problem’). This information is relayed to our data science team so that they have more information to improve our detection algorithms. Renaming devices is another way to be involved in the device detection process.
We are working on more features along these lines so that users can help our data science team and our machine learning algorithms improve device detection.
