Is it possible to setup a local Network of Things (NoT) that uses the Raspberry Pi 3B+ built in WiFi for ESPHome devices? I use a wired internet connection to Home Assistant OS for Raspberry Pi (HAOS) and want all the ESP devices on a separate network. I found a lot of information about using a regular Linux system for the Raspberry Pi to do this, but nothing seems applicable to the new embedded HAOS.
I am not interested in a external network controller/router box.
A ESP32 development board plugged in to the Raspberry Pi does not seem to work with ESPHome on HAOS. I found ways to do this with the older HASS version that does not use the embedded HAOS.
