First steps with emonESP

Does anyone know how to tweak the code to read from pins also?my sensors don’t have uart. Or can a sensor without uart be connected to FTDI?

I apologize in advance for the very basic question, but I can’t get access to the emonESP configuration page.

I could upload both sketch and data folder, the ESP8266 starts as an access point and I am redirected to the log-in page. What I could not find anywhere is what the default username and password should be.

At the moment I tried blank fields, admin/admin, root/root and other obvious combinations. I also assumed the AP name had to do something with the default access credentials, but had no success. How can I access to the emonESP configuration page?

The WiFi AP password should be blank:

openenergymonitor/EmonESP/blob/39eba77e57423fb66f6489683bce336d4d7a3037/src/wifi.cpp#L39

    
      
          
          
#include <ESP8266WiFi.h>              // Connect to Wifi
          #include <ESP8266mDNS.h>              // Resolve URL for update server etc.
          #include <DNSServer.h>                // Required for captive portal
          
          
DNSServer dnsServer;                  // Create class DNS server, captive portal re-direct
          const byte DNS_PORT = 53;
          
          
// Access Point SSID, password & IP address. SSID will be softAP_ssid + chipID to make SSID unique
          const char *softAP_ssid = "emonESP";
          const char* softAP_password = "";
          IPAddress apIP(192, 168, 4, 1);
          IPAddress netMsk(255, 255, 255, 0);
          
          
// hostname for mDNS. Should work at least on windows. Try http://emonesp.local
          const char *esp_hostname = "emonesp";
          
          
// Wifi Network Strings
          String connected_network = "";
          String status_string = "";
          String ipaddress = "";

i.e. no authentication is needed

The soft AP was working fine, and I could get to the emonESP configuration page but the login form kept showing up despite username and password should be blank.
I decided to play dirty and to ask emonESP its own password, that is, I modified the config.cpp file so that username and password were output on the debug port:


// Web server credentials
EEPROM_read_srting(EEPROM_WWW_USER_START, EEPROM_WWW_USER_SIZE, www_username);
EEPROM_read_srting(EEPROM_WWW_PASS_START, EEPROM_WWW_PASS_SIZE, www_password);
DEBUG.print("User ID: ");
DEBUG.print(www_username);
DEBUG.print("Password: ");
DEBUG.print(www_password);

Instead of empty strings I obtained garbage characters, perhaps I had flashed that memory area, or it was like that from factory. I could access the emonESP config page by copying and pasting those lines, after which I could change the credentials.
