A few years ago I built the Google AIY Voicekit, I just barely managed to get it working because I'm very poor at the software, and when it stopped working after a month or two, I moved on to other things, and it's been sitting in my basement. But yesterday I succeeded, to my amazement, in installing Homebridge onto the Raspberry Pi in the device. I then even got it installed, as an accessory, in iOS' Home. (Although I haven't figured out the next step there, or with Google Home, either. I don't really get how to install plug-ins yet.)
I have ordered a Hubitat Elevation, which should arrive in two days. Will the Hubitat help me / be useful / make redundant the Homebridge I've just now got running? How much "overlap" will there be? I'm afraid of biting off more than I can chew! I have iOS Home running on an Apple TV, and a few devices, but mostly I use Google Home to talk to / query my lights, Nest thermostat, and Wyze sensors.
And -- is it possible for Homebridge, or Hubitat, to utilize the speaker in the Google AIY Voicekit to, e.g., announce notifications? I think this is "just" a software thing, in that the Raspberry Pi in the AIY Voicekit has a speaker in/on it and should be able, theoretically, to be made to speak, as it did when running its previous software.
