HomeAssistant on RPi4 Wifi Question

[iosoft]

Hello,

I am using HomeAssistant on Raspberry Pi 4.

Can I use Pi4's 5GHz Network to connect my Home Network and 2.4GHz as Wifi Access Point for some IoT devices?

no, you could use both to connect theoretically.. but there is a hardware limitation in access point mode.

There are multiple answers here with more detail

A work around:
You can buy a USB WIFI DONGLE and use that as well as your build in wifi

Hi @iosoft - thanks for the question. As @G2G2G2G said, the answer if technically no (in regards to the two different bands).

However, I'm going to look into this PR which would enable STA+AP mode. This would allow connection of the Pi4 to your home network, and allow other devices to connect to the AP. Worth reading the PR for more information. Stay tuned.

Hi
It's possible to set both modes in parallel, but performance is horrible (pi Wireless chipset is very limited). Suggestion on use 2 adapters is, IMHO, the best setup.
