Can not discovery any device (Failed to connect)

Configuration
1

Hello,

My home-assistant was discovering everything automatically.

I had some problems and I tried to start over with a clean installation. Now it can not find devices, which was automatically discovered (shelly, roku etc.). I tried to add integration manually (shelly and roku) and get error message “Failed to connect”.

I add integration of xiaomi-mii and connected cloud-server. But I get always error:
“Config entry ‘Roborock S5 Max’ for xiaomi_miio integration not ready yet; Retrying in background”
I can not connect to roborock.

A few wired devices are connected without any problem: qnap-nas and kyocera network printer. Shelly , roku and Roboroc are connected via eero-wifi. Do you have a suggestion?

Is your eero wifi a different subnet? Or are they simple access points for your original router?

It is not a subnet but they have difference IP range.
Wired device get IP adress from Modem (192.168.0.xxx)
Wireless device get IP Adress from Eero (192.168.4.xxx)

That is exactly a subnet issue. If your subnet is 255.255.0.0 it will work. But it is 255.255.255.0, so it it won’t work at the moment.

You should reconfigure your eero wifi to be in bridge mode and become simple access points and not be a router. That way there is only one router in your network, now there are two.

I am not at home not, I will check subnet again. But i am almost sure:

I can connect shelly-gui with wired PC
I can connect NAS and Network-Printer with wireless-notebook.

Home assistant is wired and it can connect wired devices (NAS and printer) and it can see my mobile phone and wall-tablet via wifi.

It is weird.

DHCP & Nat settings of eero was automatic. I changed it to “bridge” and now all devices are found. Thank you very much.
