WebCoRE is the poster child for that. (I read that the very latest is superior but I don't know as fact.) One of the 'must haves' on my list is Homebridge. It too has wormed it's way onto the bad apps list (again, since, it's been completely rebuilt) and I created in my head a means to split the 'risky apps' onto it's own Hub.

Two have the ZWave/Zigbee radios enabled and I've split my devices (upstairs vs downstairs) between those two hubs. For 'speedy' - no other reason. The 3rd hub is in a 'coordinator' role and many apps reside there.
