I am considering the purchase of the Heatit Z-Water2 and I can see that the older Heatit Z-Water (v1) was added to Hubitat release 2.3.1 two years ago.
Can anyone inform me based on their own experience whether the Z-Water2 works properly with the Z-Water (v1) driver?
Any views on whether the Heatit Z-Water2 is a reliable product would be welcome too.
Correct. There was interest in the first generetation Heatit Z-Water -- I cannot share links but if you search here for "Z-Water" you'll find a discussion about creating "Generic Composite Driver", before a standard driver was added to release 2.3.1.
I cannot find anything about the "Z-Water2", though.
