I have an iblinds v3 device in Z-Wave JS UI that is acting very odd and I can't figure out what happened or how to fix it. The device is a "HAB Home Intelligence LLC Window Blind Controller iblinds V3" - window blinds tilt. When I look in Z-Wave JS UI the tilt of the blinds is reported correctly (0-100), but when I look in HA the value is just Unknown, but the slider control in HA does work. I can't tell if this is a HA problem, a Z-Wave JS problem, or something else entirely. It appears that the actual numeric state isn't reported back to HA, though the controls work and I can move the blinds with HA or with the Z-Wave JS UI.
It's persisted over multiple ZWaveJS UI and HA versions, currently zwave-js-ui: 9.33.0 / zwave-js: 14.3.12, HA 2025.3.3. zwave-js is connecting to HA using the websocket. I've tried the clear retained / update topics tools for the device and there's been no change in the behaviour. I've removed the device and re-added it at some point and not seen a difference either.
Any suggestions on where I can look to troubleshoot?
