the wifi network on the Protectli has a unique feature of being invisible to devices when searching for wifi networks you only know the network exists if you can type in the unique wifi network name

I think this feature is available on many routers. If you live in a densely populated area with a lot of WiFi networks around, no problem. If there are not a lot of networks around, it might raise suspicion, so you may want to have a dummy network that is visible.
