I am now well through building my home automation setup with Openhab. Next week I am expecting my Sonoff switches to arrive and I will be using those with Sonoff Tasmota to control most of the lights in my house (some others will be controlled via z-wave and others via BLE).
One thing that I want to do is isolate the network for those switches from the outside world. Basically I was just thinking of connecting them to a separate wifi router that will be just used for that and nothing else (and completely isolated from the internet). And I was then thinking of connecting my Raspberry Pi 3 via wifi to that router. The Pi would still be connected to my regular local network via ethernet.
The reason why I want a separate router not just a separate network is because you sometimes need to reboot the router because the internet isn’t working or are otherwise messing around with the local network. And I still want to be able to control my lights when that happens.
Does anyone know how to configure Openhabian to do that? Sadly my linux networking is a bit rusty and I don’t really know how to do it. As far as I know it should be possible and pretty easy.
