Hello @B_Clark,
In the end, in my case, it turned out that the issue was related to a corrupted backup. When I moved from HOMEY Pro 19 to 23, I used my latest backup, and apparently, there was a problem with it. Unfortunately, at the beginning, I didn’t even consider that my backup could be the issue. Instead, I explored countless other possibilities, wasting several weeks.
Even more foolishly, I completely overlooked the fact that I could have simply tested one of the seven backups that Homey automatically stores. Not because it wasn’t a plausible issue, but because realizing it meant having to start everything from scratch—something I didn’t even want to think about, considering the dozens and dozens of hours of work it would require.
Eventually, after testing the replacement unit that ATHOM provided, it became clear that the problem wasn’t hardware-related but tied to my backup. That’s when I had a “lightbulb moment” and decided to restore an older backup from HOMEY 19. That alone solved about 70% of the issues.
Then, Homey still restarted a couple of times, but this time, it clearly coincided with a specific flow related to my washing machine. It was a flow that notified me when the washing machine was running and when it finished, using the Countdown app. In the end, deleting that flow and creating a new one without Countdown (and just to be safe, redoing similar flows as well) completely fixed the issue.
Did you try different backups? Or just one?
Hope this helps! Let me know if you need any more details.
