This is a surgeons of a new NabuCasa Zigbee controller variation.
Many of us have the problem of multiple locations.
To integrate it together in one HA platform is not easy.
You have to either be able to use some kind of vpn and without static ip you have to have a 3d party solution for that or you have to put your trust in a company cloud and what we seen with Tuya the latest days where accounts being disabled and is impossible to reconnect, this is not a nice situation.
What I propose is a NabuCasa hubb that has SkyConnect, wifi and maybe Bluetooth, 433, Zwave… (concentrated through matter maybe) built in and is hard coded to connect through the NabuCasa cloud or directly over ethernet to a HA server.
It can be used to run a 2nd location over the internet or to create multiple device networks for separate buildings or floors on the same lan or to be used as your main hubb that can be placed more strategic then to be attached to the server that could well be in the far corner of the basement, where you happen to have your fiber connection and servers.
Tnx for the space.
