Error causing one of three shades not to open

🛎️ Get Help

C7 on 2.4.0.146. But this has been happening since the last platform version. I updated this morning hoping the update might fix the issue.

I've got 3 shades that open as a group each morning. This has worked like clockwork for years, and then recently, one of the three shades would fail to open, it's usually the centre shade, but not always. One morning I happened to have the dashboard open in front of me when the rule kicked off, and I saw the shade briefly flicker to "opening" and then to closing.

I updated to 2.4 this morning and the issue persists. Here are the logs. The java error for device 533 is indeed the shade that failed to open this morning.

Not sure if this will help but my shades work best when there is a 5 second delay between commands. I realize this just started happening, but it is something easy to try.

I don't get where this error is coming from that is telling the shade to close after it starts opening. They're set as a group, and it has worked just fine for years.
