"OpenHAB Connector doesn't exist in Z-Way server" error

I’m new to OpenHAB. Hope this isn’t a duplicate question.

My Z-Way Server panel says:

OpenHAB Connector doesn't exist in Z-Way server

I found from this post where z-way binding was originally introduced last year that OpenHAB Connector needs to be source-downloaded. Then the README file on its repository says:

The preferred way of installing this module is via the "Z-Wave.Me App Store" available in 2.2.0 and higher.

My z-way panel at http : //RASPI_IP:8083/smarthome/#/admin says as following, so I assume it qualifies, but I don’t see “OpenHAB Connector” or anything similar on my Z-way apps page http : //RASPI_IP:8083/smarthome/#/apps/online:

Software info
Firmware version	v2.3.4
UI version	1.7.0-RC-12
Built date	29-03-2017 15:36:36

Is getting it via source only available option with this situation?

Maybe let me tag @pathec the original developer of the binding.
