I have an ESP 14F which takes measurements in my garage, then uses autoconnect (192.168.4.1) to collect parameters including WiFi ID and password. The 14F uses the WiFi to put up a webpage (192.158.x.yy) to display readings on a pc or iPhone using that webpage. With pc/iPhone I click a link to request a reading.
The 14F is in a stand-alone garage, which uses walls that are virtually impenetrable to WiFi signals. The nearby house, which also has WiFi impenetrable walls, has the primary router and that router is connected to the secondary router (access point) using an underground Ethernet cable to the garage. The 14F uses the secondary router to set up its webpage.
Now I have to step into the garage with my cell phone to take readings. Can I use the Ethernet connection between the two routers to get the signal into the house, so I can use my pc/cell phone inside the house to read that webpage, or is there some other way to accomplish my goal? Do you have any tutorials/application notes addressing this problem?

With two routers connected via an ethernet cable you should be golden. You should be able to connect to the ESP32 anywhere in the house or the garage. So why can’t you? I believe you have not setup the secondary router properly. There is an article that should help (You would want LAN to LAN). Most likely is that you setup DHCP on both routers. You need to turn off DHCP on the secondary router. This way all devices only connect to the one network.

I simply tried the Cell Phone and the computer in the house, to see if the unit in the house was programmed as an access point. I was able to take readings with cell phone/computer in the house, so I didn’t have to re-program the garage unit, as it was already running as an access point.
Thanks for suggesting I try it, and it worked!
