WIFI make dialog 2 ESP8266 in client-server mode

Using Arduino Programming Questions
1

Hello,

I have a wifi module that detects the closing of a door (the server)

I have a second WIFI module (the client) which displays the status of the door: open or closed.

As long as the two modules remain in the WIFI reception area, no problem.

Now I have to move the client to an area where the wifi is not accessible.

I set up a network extender which is connected to the livebox by cable but with a different ssid.

I don't know how to configure the client module so that it reaches the server.

I hope my explanations are sufficient to help me.

Thank you in advance for your and remain at your disposal for any useful details,

cordially

What exactly is this "network-extender" and what is the "livebox" ? you wrote the netwwork-extender is connected to the livebox by cable. Does the network-extender have WiFi?

You have to provide more details. Best thing would be download-links to the manuals of each part that is involved

best regards Stefan

@danielpsk: the WiFi extender should extend the range of your Livebox WiFi so there should not be any changes required in any of your sketches. But this may depend on the extender I guess.

Another possibility would be to use an additional ESP8266 module in between the 2 others. Then use the PainlessMesh library to create a mesh network that enables the 3 ESPs to communicate.
