Can’t See Home Assistant Green on Talktalk

Stuck at the first hurdle. Plugged and powered on my new assistant green to my talktalk router but I can’t find it with the home assistant app on my iPhone or by using the web address.

What should I check? Settings in the router?

Thanks

Did you plug it in with a ethernet cable too?

Connecting a monitor to it should tell you what IP address it gets from the router.

Hi. Yes Ethernet cable plugged in. I will plug in a monitor and take a look. Thanks

Sorted now. Seamed to need monitor, keyboard and mouse plugged in to boot up ok. Now working. Thank
