I’ve got many google speakers around the house, all of them are connected to the same network but google cast integration won’t detect them. I have IP addresses of all devices, but I don’t know how to set them up.
Settings / devices & services / add integration / google / google cast.
Note following text:
Known Hosts - A comma-separated list of hostnames or IP-addresses of cast devices, use if mDNS discovery is not working.
It seems like my LAN cable is connected to different router, so solution is to connect my Rpi4 directly to router every device is connected to.
Yeah, auto discovery wont work if they are on different network
