For a long time I want to set up an access point on my Hassio device (RPi4) using an external USB dongle I had. That is for different reasons:
- To isolate my IoT devices from my main network
- To make my automations independent of the router
- Because the embedded Wifi on the RPi (broadcomm chipset) has very unstable drivers, and keeps on dropping connection, making automation unreliable.
Said so, I needed to configure the Hassio with an external USB dongle, which was impossible due to the lack of drivers. Instead, I made a fork of the Hostapd addon, that actually install drivers for the most common USB Wifi dongles, and let the user select the network interface in which it wants the access point to be configured to.
Find below the link to the repo from which you can install the addon:
