I believe it is the case that the settings for "IPv4 gateway" and "IPv4 address" must not be identical (see my tale of woe, below).
If so, the Almond+ should not allow you to set them identically. Doing so prevents access to the web console and requires a hard reset to correct.

On first setup I decided to relocate the subnet to 192.168.x.x, because that's how I've always had my home network. And on past routers I've been used to having the http console and the gateway live at the same IP, namely 192.168.23.0.
When I entered the IP address of 192.168.23.0, the router I assume set the gateway and the web console at 192.168.23.0... I could get a DHCP address in 192.168.23.x, I could connect to the internet, etc. I could not, however, connect to the web console --
http://192.168.23.0 returned an access denied response. And you can only change that setting from the web console, not from the securifi cloud.
A hard reset later, I set the web console to 192.168.23.254 and the gateway explicitly to 192.168.23.0, and now everything is working like Hoyle.
