Network error on initial setup of Home Assistant Green

Hello all,

I recently picked up a Home Assistant Green, and I haven’t been able to start the initial web setup.

The device connects to the network with a valid IP, and can be reached by other devices via HTTP. However, the web UI complains that the supervisor setup cannot continue, claiming no internet connection.

I connected the device to a keyboard and display to check the output, and the only error is related to the realtime clock. I’ve included the output below.

Waiting for the Home Assistant CLI to be ready…

[117.863655] rtc-pcf8563 1-8851: low voltage detected, date/time is not reliable.

If anyone has any information that might help, please let me know.

Thanks,

Just wanted to add, I thought the realtime clock error might be due to a bad 2032 cell, however I added a new one and the message still persists.

Did you find any resolution? I have the exact same problem. Already regretting this lol

Same issue here with Green.

Since you are tagging on to an old post, please start over.
Assuming your issue is the thread title, what do you see on the Home Assistant console for IPv4?
And to avoid 20-questions, what is the IP of your browser and PC?
Post the results of ha network info

Resolved.

Situation was as described above: new green box installation, box boots, is on the network, but connection refused on both mobile setup and web (port 8123). Console accessible.

Two apparent issues:

  1. Potential DNS block. pi-hole may have fubared name resolution. The fix: set a static IP with different DNS (e.g. 8.8.8.8) in the DHCP settings in your router. Unsure if this was the root cause but flagging it here to cover all bases.

  2. No battery: my green box shipped without a 2032 cell, producing ‘low voltage detected, date/time is not reliable’ msg, and potentially messing with certs. The fix: install a battery (or check it; others have reported poorly-seated batteries in the green box) and confirm the date/time (e.g. date -u) in the console.

Solution:

  1. Ensure names can be resolved (1 above)
  2. Ensure certs can certify (2 above)
  3. Reset the device (Step 2, here)

Resetting with an operating DNS and accurate clock allows the latest version of Home Assistant Supervisor and Home Assistant Core to be downloaded.
