can I add a web in wifimanager for example 192.168.1.1 is the wifimanager settings display then 192.168.1.1/ui is the rc car control, is there a tutorial for making it?
what do you mean by "add a web"? have a field where an URL can be entered?
(WiFiManager creates a captive portal, so the IP is irrelevant - you get the portal in your web browser / configuration settings when connecting to the hotspot)
I want to make it so that we can open the wifimanager portal and the web portal. Later there will be 2 websites, for example page 192.168.1.1 is the wifimanager portal page but if I add /ui behind it it says file not found uri get. I would like to be able to page the sensors I have as well on page 192.168.1.1/ui
Is that your home wifi or a self assigned IP for the ESP32?
It seems the same also to me.
Since this is a situation that often happens in my projects too, I developed a library specifically for this purpose to have a working base and not start from scratch every time.
Basically it's a wrapper of the WebServer.h library included in the Arduino core with the addition of a captive portal (as in the wifimanager library) and some others features (OTA, ACE source editor etc etc).
This means that everything that is done "in the background" by the library can be replicated even without it if @bimosora wants have some practical examples to investigate.
