Third Reality zigbee blinds. They're super-fantasic:

  • accurate reporting of alkaline and NiMH battery lvl
  • puts up with NiMH
  • keeps blinding muni lights from ruining sleep
  • work well with a virtual device and mirroring to orchestrate multiple windows (blinds)

... Until the direction for open/close inexplicably inverts. No obvious relationship to hub updates or reboots. A shade will just suddenly have gone the wrong way through some progressive open/close sequences I have programmed.
I can invert the direction with the boolean device configuration option, but that only affects the open/close and level... These shades are sold by width and not length. There is a little contact switch on the bottom of the shade, so if any custom calibrations to stop on closing that fail the hardware backstops it. That same switch stops functioning during these inversions.

Has anyone experienced and resolved? anyone know if there is a readable device attribute or some app out there that I could at least bind something to a notification rule to let me know when it happens?

I've got houseplants I'd like to accommodate when I'm out of town, but I don't want a window shade all the way open after sunset when I've got automated lighting running.

Can't help, but here's a bump, as they say, for the great thread title!

Can't really help you out, but a least I now know I'm not alone !!! I built my own blinds using "Rollerhouse" blind motors controlled by RF signals from a BroadLink RF/IR controller through Hubitat, or a handheld RF remote. I've also had the directions reverse on their own accord several times on different blinds. Unfortunately, the only fix I've found is to re-program the motor using the handheld remote.

Every once in a great while one of my IKEA blinds will not stop at the lower programmed limit, and will continue closing until the blind wraps itself backward.
