The 700 and 800 chip z-sticks will work in OH after OH4.0 in “Classic” mode nodes up to 232. Long Range inclusion, nodes over 256 require S2 security, smartStart are not supported by the OH ZW binding. There might need to be an adjustment initially as the latest Zooz sticks are shipped with 16 bit nodes as default. This is fixed in the OH 5.0 snapshots.
Another idea is that there is a combined zigbee/zwave device in a similar forum topic Migrating Z-Wave, choosing device for the next 5 years - Hardware / Server - openHAB Community
