IOS 15.7.8 stop my ipad mini as Home hub, solution?

Hi,
I’ve been using my old ipad mini as an Apple Home hub for two years; Yesterday I updated to iOS 15.7.8 and it block iPad as Hub. Obviously only for external network access.
I’ve been reading many time that Apple would only accept HomePod or AppleTV as a Home hub.
Have you found alternative solutions/workaround? Or do I have to buy another Apple device?
Thanks
Luca

If you want the hub then yes you need to purchase another device. HomePod mini would be the cheapest.

Why do you want the hub though?

Home assistant can connect directly to HomeKit devices.

Thanks for the reply tom_I.
Yes, HA finds devices compatible with Apple Home. But I find it very safe to remotely control my home via Apple Home protocol.
Maybe I’m wrong, but I find it the safest method.
