Is it possible for this to automatically switch without needing to set the same SSID? 

 

Yes, it is possible, but the switch has to be initiated by the client device.

Depending on what operating systems your devices use there may be software available for this purpose. In case of Android you could try if "SmartWiFiSelector" (use the Trial version first) from the Google Play Store works for you.

  @woozle I have an iPhone and I looked at 'wifi selectors' but I'm not sure that any of them are going to do what I need - can you advise? is there really an app that can help switching between signals?

  @winedineroam 

It's possible that there is no such app for iPhone. 

I don't have an iPhone myself, therefore I can't test any apps. But if an app doesn't specifically say in the description that it can automatically switch to the Wi-Fi with the strongest signal, then it's not what you need.
