Terry,
I managed to find the app called “Hunter Douglas Platinum Shade” but that is for older hardware that HD no longer sells (Hunter Douglas Platinum Gateway) and is not supported by the current Hub. I believe that Gateway was replaced by the Hub (ver1) and that was replaced with Hub Ver2.
I just installed it and it created a device, but it doesn’t show up on the list. I used ALTUI to find it, but there was no ability to change any relevant settings. My guess is that the app did not work properly.
I recall way back when - 2016ish, that I investigated this app and couldn’t make it work with my HD Hub(1), that’s why I went down the path of using LUUP to control the shades.
This is the link to that conversation
If you’re interested, I can share some of my LUUP code, but if you’re not familiar with LUUP, it will be a bit of a learning curve.
