To install Home Assistant on my Raspberry Pi 5, I had to use my phone's data connection by tethering | Home Assistant | Page 1

When the Raspberry Pi was connected to my home Wi-Fi, it kept giving me an error that the supervisor couldn't connect to the internet. I also noticed the time was completely wrong. I tried pinging Google's DNS servers from the shell, and that worked, which proved the Raspberry Pi had internet access but couldn't get the correct date and time or connect to proceed with the installation. So, I switched to using my phone's hotspot by connecting an ethernet cable from my phone's USB-C port to the Raspberry Pi, and this allowed the installation to complete.

My provider is Eolo, and I can't open ports because I don't have a static IP address. I also don't even have a router page to access and configure things (I know it's strange, but if I literally try to connect to the gateway's IP address, nothing exists).

This issue where the supervisor couldn't connect initially—could it be a problem in the future? Right now, Home Assistant works even on my home network, and with Dataplicity, I can connect to it remotely and it communicates fine with external services like Google, but I'm sure the supervisor problems will reappear.

Do you have any advice or information?

Where did you plug the pi into before?

Before I connected it to my phone's hotspot, the Raspberry Pi was connected via an Ethernet cable to my home router.

glacial goblet Can you connect it again and share `ha network info`?

I'm not sure if fixing the time using my phone's connection will now allow it to work on my home network without any issues, but thank you so much for your help.

That looks okay. Maybe NTP is blocked on your main network?

how can i check that?

#

maybe with a ping from the console?

If you tell me the address of the NTP server that Home Assistant uses, I'll try to ping it to see.

I think it uses time.cloudflare.com but pinging it is very different than using NTP.

You need a NTP client but HAOS makes that a pain.

What if I just ignore it and, since Home Assistant now has the correct date and time, I just use it as is? What problems could arise?

Not sure. Guess we'll see.
