Yes. There’s no support (hopefully just yet) for multiple Home Assistant instances with the same account.
homeassistant
Home Assistant is open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server. Available for free at home-assistant.io
Which makes sense.
No it doesn't?
Yes it does. Each instance requires its own connection, which costs money since they use AWS.
Could you make a VPN between the two sites and put them in the same network? Then maybe you could separate them in the UI into different views?
Ive always had a VPN going, but it just makes more sense to keep the control local.
What do you get with subscription? I wasnt aware there is one
If you're using Voice Assistant, the recog and TTS are much faster and more fluent than what I've seen on my own system. I am running it as a VM on an old server, so hardware will matter, of course. Also, you can get remote access with Home Assistant Companion proxying your HA interface very seamlessly. There might be others, but this is what stands out to me.
You might be able to do something with local Zigbee2mqtt or Zwave2mqtt proxies at the cabin, and tie those areas back into the main instance over Wirguard or Zerotier, but you'd need a pretty reliable internet service at the cabin to do so.
I don't use those proxies myself since ai just use the one local hub, bit it should be possible. Maybe someone with more experience with those proxies could chime in?
