I also have a few motorized TDBU. Each of mine are paired as two separate shades - the top bar, and the bottom bar. As you wrote, if you use the bottom bar only, it works just fine with the default drivers.
However, I typically use the top bar only, and it is always exactly opposite the default language.
This works fine as I am aware of the issue, but it makes dashboards unusable for my household.
- First was a plea for Hubitat to revise the default language from open/closed to up/down, but that has fallen on deaf ears.
- Then I tried to edit the driver on my own. That was a disaster.
- Then I tried to reset /switch the top bar so it would think it was the opposite of what it really was. That only worked for one cycle, and then it "corrected" itself.
- Next (probably over the holiday or this coming weekend), I'm going to try this: TDBU shades - revising shade driver for top bar - #4 by calinatl
