HASSOS/HASSIO RPI3 setting up hotspot/AP

Hi everyone!

I’m trying to create hotspot/access-point on my RPI3 running HASSOS, so I could connect to RPI though phone or computer without router. I tried a lot of configurations of system-connection, but only what I can do it based on router wifi. Is there option for configuring stand-alone local wifi/hotspot/ac so I could directly connect to my main hass page?

I have tried everything from this.
Also I have set up DHCP addon, but it’s still not working.
