This is just weird to me, I’ve got a few automations for my Fyrtur shades. If I set up “Dining Room Shades” and “Living Room Shades” groups (each group with 3 shades), and then add those groups to an automation, the vast majority of the time one of the 3 shades moves a few inches and then stops. It happens whether opening or closing.
This is not motor-related; if I add each individual entity to the automation, it works perfectly every time.
I’ve figured out a workaround (using individual entities) but it’s just weird, which seems to be on theme for what the blog post was talking about reporting here.
