Setting up HA on a Raspberry Pi using wifi?

I’m trying to set up HA on a raspberry pi 3 (built in wifi). I’m wanting to use the lite HA Raspberry pi image, but the issue seems I have to be connected to the internet when I set it up for the first time. I tried to just not connect it, then edited the wpa_supplicant.conf file to connect to the wireless network. The issue is since it wants to set it up on first boot, it won’t set it up on second boot connected to the wifi.

Then the issue I have with HA is that it seems that once it is set up on a lan, I can’t switch it to wifi, the IP address doesn’t switch for HA. For example, when I first set up HA using the image and a LAN cable, it was attached to 10.0.0.5, but when I connected to wireless, it switches to IP address 10.0.0.8. After this, I can’t seem to access HA anymore. Any ideas for how I can go from a LAN setup to a wireless setup?

I had an issue with connecting to WiFi by editing wpa_supplicant.conf, in that it was only accessible over WiFi when there was an ethernet cable connected (even though they have separate IPs of course). I was probably doing something wrong, but my experience with Linux is pretty minimal.
The way I got round it was by booting into the Raspbian desktop and configuring the WiFi that way. I’m not sure how the image to which you refer is set up, but if you have the option of booting to desktop, it’s worth trying it.

Hopefully this helps, helped for me raspberry pi 2 and 3
