Question: UI not loading

[Nyc0]

Hello, this add on sounds great but I am unable to start the UI. I tried for following URL: http://homeassistant.local:8123 or http://192.168.99.1 or http://192.168.99.1:8123

My generated IP was 192.168.99.19. What am I missing?

Hi @Nyc0 - I'm not too sure. One thing I'd not considered with this is https. Do you use https for the home assistant installation?

http://192.168.99.1:8123 should be the correct address. Try changing the address to something else, either on the same .99. range, or change to something completely different (not forgetting the DHCP start/end addresses).

Hi @mattlongman, thank you for your quick response. I figured it out. I was using the Raspberry Pi on wifi already, and switching to its own wifi network wasn't working. I restarted the Hass.io configuration from scratch, but this time using ethernet. Your addon worked first time. Thank you!

Here is what I had initially followed to configure the Raspberry Pi and Hass.io on my home wifi https://www.youtube.com/watch?v=SHg6fa0x7OA

That setup would theoretically be possible if you had a separate USB WiFi dongle, but the home assistant fix to allow the extra drivers for some common ones is currently in dev (or maybe beta). So in future, yes.

The alternative setup for a pi that is already using the onboard WiFi is to change wlan0 to whatever the ethernet is and directly connect a device to ethernet (although it's been a while since I've tested that. EDIT: won't work for internet routing at the moment. Looks like I've hard-coded 'eth0' into the iptables lines.)
