Trust me, if this was a simple software add, we would do it. Training Sense is not nearly as simple as training something like Alexa or Siri. Many, many discussions on this forum go deeper into the challenges there, but this thread is a good start: Why can't you train Sense?
@andy I think we’re pretty upfront that Sense will not detect everything and that many devices will take a while to find. This information is included on the FAQ right on our main page. I’ve said this before, as have others, your situation is pretty unique. I’ve yet to come across another customer with a similar setup that prevents proper device detection due to a single device. If you, or anyone, has ideas on how we can better set expectations, I manage the bulk of our blog and help content and will happily take all ideas into consideration.
