Consider leveraging the HA ecosystem of integrations, but for automations add Node Red. There is a well maintained WS node to HA that lets you call any service/action in HA and listen for events or device state changes. https://flows.nodered.org/node/node-red-contrib-home-assista...
Along with everything else NR provides like MQTT pub/sub, only limit is imagination and time. I've been doing this for years. Another moving piece I know, but it has been bullet proof for me
I can second Frigate and welcome any work in this space, so nice work OP will have a look. For others asking, I have found so far Hikvision POE PTZ domes like DS-2DE2A404IW-DE3 have been reliable, depends on your budget. I have cams themselves fully locked down from internet and on a separate subnet on the local net. OPNSense is also a friend here. I would love some OSS firmware for these cams. For remote, I find ZeroTier to Frigate & Home Assistant machines is all I need. I get why others WireGuard too. YMMV
Oh wire guard is a requirement imo, regardless of NVR or camera vendor. I'm less worried about a nation on the other side of the Pacific getting a livestream of my property than I am someone social engineering some rando employee at Ring/whereever and figuring out the best time to rob me or whatever.
Also set up alerts on shodan opencve etc. If you have anything but a phone and personal computer on your home network, assume they're hacked and treat it like you would coffee shop wifi during defcon.
Because... Well they are. Zero days are a thing, and by definition by the time you learn of one it's too late.
Honestly I'm more concerned about the compromised device being an attack vector for network sniffing etc moreso than the video itself... Which is yet another reason why I try to 100% VPN even at home, but man okta doesn't play well with VPNs.
It is self hosted, offline by default, with options to use various ASR and TTS engines, some online, depending on your own privacy, performance or quality choices. It's quite mature and the maintainers are aiming for a 1 0.0 version release. I have been running it as the primary voice interface to my home automation system for years.
As someone else said elsewhere, there are a few assistants around now. Perhaps there is some benefit for sharing of resources too, as all struggle for contributors.
Minor correction, I don't think Datomic is used. I believe it uses a variation of DataScript and in turn DataLog for queries. Whereas Datomic is a DB which is also based on and uses DataLog queries.
