Z-Wave 1.9 binding with OH2

This depends on the OH2 version you are using…

Former versions (beta 4 or snapshot versions prior to #624) are using mapdb to store the data. The most recent snapshots of OH2 are using jsondb.

In mapdb you can’t “have a look” at the data, it’s not human-readable. The json files are readable (and can be modified). See this thread:
