Not really. I had a major update to OpenHab which to be frank, isn’t the best at regression and backwards compatibility, and that kippered a lot of stuff, but once I had worked through those everything was back to normal.

Batteries run out, and sometimes kit can fail (touch wood I haven’t had that).

Though I think if you go down the commodity route with a mixed in ecosystem, you’re more likely to hit issues over a more involved system.
