So yeah, that sucks - I just came home tonight to a corrupted C5 - this one only had network and cloud devices on it. NOT running the latest firmware on this hub. Fortunately the diagnostic page :8081 came up and was able to do a soft reset. PAF (Partner Approval Factor) was really really low..
I'm not really sure where you would go from here? Every platform will have issues - if you are a tinkerer you can try "home assistant" and the UZB-7. You can also share those devices with HE using the HomeAssistant Device Bridge... so that might be an option while still keeping HE around.. Warning cool stuff in HA but also dragons..
If you want to spend the big bucks on a complete system then Control 4 or Savant.. on the hub front there is Homeseer or you can go with the data collection giants - Amazon Alexa, Google Home, Apple Home. Each system has it's own set of cool capabilities, restrictions, frustrations, limitations etc.. so ymmv.
Any hub/system in particular you are interested in?
