Connecting to different IP subnet

Hi,

I want to connect to my home generator web server at 192.168.0.90 by WIFI for use in HA. However, my HA ethernet network is 192.168.1.x determined by a FIOS router.

Purchased an external USB antenna to attempt a connection. I am using the Raspian image install of HA.

I am stuck at this point. Is this the way to go? Has anyone done this before?

Thanks,
Rich

I assume your “Wifi” router is connecterd to your “FIOS” router?
Do you explicitly want 2 networks? If not, you can try to put your Wifi router in “Access point” mode or equivalent, so, that your main router provides the IP adresses.

Chris B,

My FIOS router is a gateway router with fixed IP addressing of 192.168.1.x. My home generator also has fixed IP addressing of 192.168.0.90.

Is it recognised by the OS ?

Raspian image install of HA ? Is that HA OS or a venv install on Raspbian ?

I am using the Raspian image of HA. Don’t know how to tell if antenna is recognized.

Raspian image of HA is nowhere to be found in the official installation guides.

What does settings->system->repairs-> 3dots in the upper right corner->system information say ?

So you are using HA OS.

Under settings → system → network, do you have a wlan tab ?

Yes I do.

So I just now selected WIFI under it and see the generator, so I added the password. It now says connected.

Then I added this binary sensor but it says “off” under STATES in Developer Tools. However, I can access it on my phone by going to 192.168.0.90.

Can you ping from one of the SSH add-ons ?

Yes, tried from the Terminal Add-on, no response was returned. I was able to ping 8.8.8.8 plus my FIOS router successfully.

Could be, on the same page, that you have to change this too:

(The extra choices only show , when auto configure is not selected)

I don’t see that page. I am using Ethernet to connect to network.

I had previously disabled WIFI chip on board some time ago but don’t remember how. I believe it was at boot time don’t know how to to those options.

it is on the bottom of that page.

Correction…

Ok, scan for Wifi, password, but IPv4 has to be automatic

Same result with 'Automatic" selected.

So I removed external antenna temporarily, rebooted HA and only the SSID ‘NotAvailable’ shows up which is my FIOS router’s WIFI SSID.

I was told Rapsberry PI WIFI chip needed to be disabled which I figure means 'NotAvailable SSID should not show up HA.

SSID ‘Champion-2799’ is for the generator which I am trying to use external antenna for.

Pinging to it still fails but still able to ping 8.8.8.8

How would one disable the WIFI chip on Raspberry PI 4 but not the WIFI software so that external antenna could use it? How can I see the BOOT options?

You still see the Wlan tab with the USB adapter unplugged ?

Yes. It just lists the SSID for the FIOS router.
