IPv6: ADDCONF (NETDEV_UP): wlan0: link is not ready
brcmfmac: power management disabled
These are not errors. Both messages are present on a working install.
They continue to be posted by people who aren’t familiar with the logs as a reference to a problem. Then similar minded people search for it and find these threads and this becomes kind of a loop.
IPV6 for wlan0 (wireless connection) is never going to be ready.
Power management for wifi is indeed disabled. Again, you would see these messages on a normal working install.
Your installs may be having a problem pulling down the Home Assistant image from docker hub because of some networking issue. Sometimes DNS is the problem. Sometimes the time (ntp) servers are not being reached or are otherwise blocked and the time is wrong. If the time of the device doesn’t match the time of the server where the images are downloaded from, the request will be rejected.
There is a console.
You hit enter at the os log screen, then enter root to get to the Hassio cli. The Hassio cli has limited custom commands for checking Home Assistant itself. If Home Assistant isn’t running these aren’t going to be much help. So, from the Hassio cli you enter login to reach the host.
From the host ( # ) you can use commands like docker ps to see whether you have both running containers: supervisor and homeassistant. You might be missing the homeassistant container if a connection could not be made.
You can also enter nmcli to check that your ethernet has an ip address. If you see an ip address, you should be good. Enter http://that_ip_address_you_see:8123 in a browser from a device on the same network.
I’m not a dev or even very smart but I’ve set up Hassio many many many times.
My advice:
- make sure your power supply is good. (5V 2.4A) Docker is power hungry. A blinking red light is bad, but a solid red light is not a guarantee that the power is good.
- If you’re using an SD that had something on it previously, use a tool like this one before flashing with etcher https://www.sdcard.org/downloads/formatter_4/
- set up over ethernet and configure wifi (if you must) after you have everything going. Don’t attempt the USB wifi config right from the start. https://community.home-assistant.io/t/guide-connecting-pi-with-hassos-to-wifi/98768
- check your ethernet cables, maybe try a different one.
