I have a 2nd-gen chromecast, it’s factory reset. If i plug it in all it tells me is to install the app to start configuring.
I don’t have a google account not do i want to install/use google-related stuff on my phone.
My home router doesn’t register any new device, which makes sense since the cast doesn’t know the SSID/pass of the WiFi.
Does it try to ping some service/port? Multicast perhaps? Where would it get an IP from without authenticating?
My (wired) PC runs gentoo.
How can i get it to work in these conditions?
If I recall correctly it sets itself up as a hotspot (no Internet access) and your phone connects to it to set it up. It may use Bluetooth, but that could also be a different version.
AFAIK the Google Home app is required to set it up, but once set up you can remove/uninstall the app.
In terms of being on your network it will broadcast itself as available on your network.
It also does auto-update, so it will expect Internet access. (It also periodically checks for Internet access.)
