Let's Control It

I have quite a large house and as a result, I am using 2 different Access Points for my network, covering ground and basement and top floor.
AS a result, I have 2 SSIDs on my network and programming ESP I need to make selection, which SSID it will connect to.

Would it be possible to add a sort of fallback SSID to connect to? This way, it would try the main one and if it would not find it, it would connect to a backup one. I have seen the LUA code for such fallback here: http://blog.jokielowie.com/2015/10/domo ... omment-287, so it would be nice to have something like that build in Easy ESP. What do you think?

any reason not to setup same ssid, key and encryption on all your wireless routers?
I have a few running and just make sure I set the wifi channel manually to 1,6,11 to eliminate interference.
WiFi devices connect to the one with the best signal on boot. I have a few phones and tablets (iCrap and Android) as well as linux, windows and mac os laptops using the setup without any issues.

Not to dive into details, for specific reasons, they are kept separate and need to be recognizable.
