@MrTheBarbarian Thank you for your contribution. We'll test it out.

We already have this in the current code (here and here), not in definitions.h. @toblum cant users just comment/uncomment here?

   // Uncomment if you want to restart ESP8266 if it cannot connect to WiFi.
   // Value in brackets is in seconds that WiFiManager waits until restart
   //wifiManager.setConfigPortalTimeout(180);
 
   // Uncomment if you want to set static IP 
   // Order is: IP, Gateway and Subnet 
   //wifiManager.setSTAStaticIPConfig(IPAddress(192,168,0,128), IPAddress(192,168,0,1), IPAddress(255,255,255,0));

If it is ok that I throw my humble opinion in here:
I would prefer changing the static IP in definitions.h like @MrTheBarbarian did, instead of changing it in the McLighting.ino.
