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?
