The pepper1 device database is no longer maintained, and is already woefully out of date.
For example, the Jasco-manufactured GE switches, dimmers and motion detectors are all missing, even though they are probably the most widely-distributed Z-Wave devices in the U.S., appearing on the shelves of Lowe’s, Home Depot, and Walmart.
So … there has to be a way that we can make our own entries into our local copy of the database. Uusually, when I have a question or problem like this, I find that someone else has already solved it.
