Motion Blinds open and close without automation

I am new to Home Assistant. One of my first integrations is the Motion Blinds.

I have 8 blinds (4 rooms with double windows) connected to a hub. In the Motion Blinds App, I have defined scenes to open and close the blinds in pairs. I then scheduled the scenes to close the blinds at sunset and open them at sunrise. This works as intended.

After I implemented the Motion Blinds integration in Home Assistant, I can manually operate the blinds. However, the blind pair in one room will open at 10:30 PM every night and then close at 11:35 PM. In another room, the blind pair will close at 2:30 PM. It appears the scenes in the hub are getting executed.

If I shut down Home Assistant, these openings/closings stop. The opening/closings do show up in the blind history.

  Bedroom blind left was closed
  11:35:10 PM - 17 hours ago

  Bedroom blind left was opened
  10:30:20 PM - 18 hours ago

Anyone have any ideas where these commands might be coming from.
