SmartHome/J is a set add-ons that are implemented on top of openHAB Core APIs. Some addons have been forked from openHAB Addons.
All addons of version 3.1.x and 3.2.x are equal in feature (where technically possible). SmartHome/J 3.1.x is considered EOL and will receive only security updates until the next major openHAB release (3.3.0).
