FWIW, I have been using a ZIR for about 5 months now and it works well for z wave receptacles, door locks and on my garage doors with a Mimo2. The zwave dongle was horrible on the locks and range was never there even with repeaters. The ZIR doesn't have that issue.
I am hoping they are still tweaking as I do still need some updates on the lock driver, the status "works" but is not something reliable at least with my schlage locks. The driver will trigger the status change before the lock actuation not request status after so if there is a jamb or you use a programmed function like a UI key with "lock all" status is not correct. Also adding codes and users was availble with the c4 drivers but not with this universal one which iss annoying as it would be nice to add and pause users.
The contact sensor also needs channels added into it as I currently cannot get status of the garage doors, it's all wired but since I cannot get status I can't add that in currently
Overall a great idea but still needs a bit of refinement. If you would like some z wave functionality then it can be done, and if you can write drivers then I'm sure this is even more powerful of a tool.
Last item note it is limited to 50 items so in the case of my garage doors even though it's 1x mimo2 connected there are 4 channels/functions connected so that does count as 4. If you need more than 50 you could use a second device but so far I am still 41 devices away and besides possibly a few blinds I don't have much more I would be adding.
