New user here - just got the C5 Friday and set it up yesterday.
Bought it mainly to bridge inexpensive SmartThings Leak Sensors into Homekit. To that end I only installed two apps -> Maker API and Lock Manager. On my homebridge I installed the Maker API homebridge plugin. All works fantastically. Even my problematic Schlage Lock, the older non-ZWave Plus version of the BE469, though I did have some issues with Lock Manager at first until I reset all codes.
My smart home is rather simple, but a mix of items, most native homekit.
I have a ecobee thermostat, hue hub and bulbs and dimmers, ikea gateway (currently unused), bulbs and outlets (paired with hue hub) and switches, iSmartGate garage controller, Sonos speakers,. AppleTV and 1 FireTV.
I previously ran Home Assistant with an Aeon Labs USB stick and a few Zwave devices. I have a mimolite (used for garage but now unused), Leviton DZPA-1BW plug which I used to control an Amp (now just used as a ZWave repeater for the lock as it supports beaming) and the Schlage Lock. Oh and two Nest Protects (also bridged in with homekit).
Im not paranoid about security but would like local control if possible... dont want paper weights when the internet goes out or company goes out of business.
Since I use homekit for my automations and UI frontend I wonder if there is any benefit to me migrating everything to hubitat and use it as my platform vs. just using it as a bridge to homekit.
There is no doubt more advanced automations that I can do but I find that homekit and siri shortcuts covers me pretty well.
That said I am open to be convinced. The bulbs for example, could they be paired to Hubitat directly? Any benefit to that vs. the Hue Hub? Create one strong zigbee mesh vs. 2. Its kind of why I paired my ikea bulbs to Hue (the Ikea Gateway is flaky too...)
I don't really use voice control -> but I could use Alexa or Siri equally as easily.
