Is there any way we can set it up with Sonoff or do we have any alternate products that work for my case?

I am in the process of automating my ceiling lights and bedroom lights with Sonoff smart WiFi wireless switch. It worked great but the problem is, i cant switch on/off manually with physical switch in the event of WiFi/internet goes away. Is there any way we can set it up with Sonoff or do we have any alternate products that work for my case? In fact this is everyone's limitation when it comes to Sonoff switches.
