Using Harmony HUB with openhab

Hello all,
I heard that the harmony hub API was closed from Logitech end of last year. Is it still possible to use it with openhab? Or do I need to consider sth.??


Yes, it is! You have to upgrade firmware of harmony hub to “v4.15.210 DEVELOPER”. (to reuse XMPP)

See here
and here (a manual to update to v4.15.210)
and here
Or here using WebSocket connection!
