Esp8266 Admin IPv4 als Arduino Tab.
In der IDE unter Werkzeuge auf lwip Variant: "v2 Lower Memory" stellen.
Die LittleFS.ino/Spiffs.ino ist zum ausführen der Admin.ino erforderlich.

Die Funktion "sketchName();" muss sich im "Haupt-Tab" befinden.
Dies ist durch eine Änderung im Esp Core ab Version 2.6.0 erforderlich.

char file[sizeof(__FILE__)] = __FILE__;
char * pos = strrchr(file, ); *pos = '\0';
return file;

void setup() {

.........
Die Funktion "runtime();" muss mindestens zweimal innerhalb 49 Tage aufgerufen werden.
Entweder durch den Client(Webseite) oder besser im loop().
*************** Aufruf runtime() ******************
void loop() {
......
.........
if (millis() < 0x2FFF || millis() > 0xFFFFF0FF) {
runtime();
