[Help] Raspberry Pi5 Home Assistant site can't be reached?

[xunsam (Sam Zhou)]

I follow the installation instruction to install HA OS on a new RPI5 (using the link on HA page). But I can’t get the Home Assistant page to load from my laptop.

Here’s what I did and observed:

1. wired network connection: I connect it with a lan cable to my xfinity router. I also turn-off xfinity’s advance security.
2. found ip 10.0.0.39 and ping successfully.
3. rebooted the router and RPI5, HA page still not accessible
4. But the observer is working at 10.0.0.39:4357. But it shows Supervisor: Disconnected.

Any idea how to solve this problem?

Install a display on the Raspberry then post the startup display. You should get something like this.

If you don’t see an IPV4 address then your Raspberry is not connecting to WiFi.

then your Raspberry is not connecting to WiFi.

That would be expected.

I meant network- but you knew that.

Well, problem disappear. I plug a monitor and keyboard, then reboot it. Now all working. Maybe it needs 5 hours to get dns to register locally?
