If nixie clocks device is not yet configured, after power up it runs AP wi-fi mode (ssid: "NixieClockXXXXXX", where XXXXXX is MAC address of the device; and password: "00000000"). In case if nixie clocks device is already configured, you can always reconfigure device by pressing and holding Button 4 (on some devices this button is located on main board in the left-front corner).
Connect to AP provided by Nixie Clock from Mobile Phone or PC, and then open web-page https://nixie-clock.local/ in browser. If your device (PC or Mobile Phone) doesn't support zeroconf, then use https://192.168.4.1/ url.
If nixie clocks are configured to connect your Home AP, then connect to your Home AP from Mobile Phone or PC, and then open web-page https://nixie-clock.local/ (or https://ip/) in browser.

NixieClocks support digest authentication over https. So, they can be esaily integrated to Home Assistant. For example, here is the curl example on how to get current temperature from the NixieClock device:
curl --digest --user admin:password -d "name=temp" -k -X POST https://192.168.1.68/param
You can make NixieClocks to play desired melody (number 5):
curl --digest --user admin:password -d "name=play&value=5" -k -X POST https://192.168.1.68/param
