This is a known situation. I asked about it 2 years ago and the maintainer explained it here: Mios Binding Thermostat transform
Sadly, I believe @guessed is no longer with us given he has been idle since May.
As for me, the 1.x binding works great. I use a vera edge for zwave only. I run OH in a VM and I have several instances of OH running so a zstick wouldn’t be a very good option.
Hopefully somebody else will someday build a new mios binding to keep us running.
