I wish there was better designed competitor. I don't like the all-in-one blob architecture as any upgrade is pretty much "your automation will not work during it", and there is no good way to run it in HA.

I'd like to see some that have separate "rule running engine hub" (that can be run in some kind of active/passive HA) + "UI/editor" (that if required can be run on separate machine so the "hub" could run on even weaker hardware if needed)
