Direct Connect allows you to bypass the Axial Control cloud server and connect direclty to your home computer. For this to work consistently, it requires this:
Once you have the above requirements met, you can determine your external IP address by visiting a site such as whatsmyip.org. You'll use that IP address as your host on your phone (or optionally the dynamic dns host if you don't have a static ip).
This describes how to use your smart device on your home wifi to directly control devices in your Axial Server.
A few notes about this setup... this will only work while you are physically connected to the same WiFi network as your Axial Server computer. Additionally, some routers will assign a new IP address to your computer when you reboot it, so you might consider assigning a static IP so the address doesn't change.
