I’ll need to wait until we get some community reviews first since I can’t try these myself (EU zwave), but we’ve definitely had people asking about them in the past, so this is very good news. 
One community member was able to get the Quinto 5 button switch from Heltun to work by using the Zooz power strip DTH. But they were only able to get on/off, no advanced features. Hopefully the new integration will provide more.
Here’s the old discussion thread if anyone is interested.
