Hi,
I try to set the deep sleep mode with wifimanager and I cannot get the full deep sleep mode.
Without wifimanager I get 0.25µA in deep sleep mode but with my code even if I bypass the init in the setup I get 15mA of consuming.
Is there any solution for this issue ?

`
#include <WiFiManager.h>
#include <ESP8266WiFi.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <RH_ASK.h>

bool SerialPrt = true; // Si on veux la sortie série
long Time2Sleep = 30e6; // Temps du Deep Sleep en secondes
String Message = "";
int CapteurTemp = 13;
int TXRF = 12;
int RXRF = 0;
int Bpy = 5; // si passé à 0 alors on bypass

RH_ASK driver(2000, RXRF, TXRF, 0);
OneWire oneWire(CapteurTemp);
DallasTemperature sensors(&oneWire);
DeviceAddress sensorDeviceAddress;

void Transmit(String ToTransmit) {
byte DataLength = ToTransmit.length() + 1;
char Data2Send[DataLength];
ToTransmit.toCharArray(Data2Send, DataLength); // Converted String to char.
driver.send((uint8_t*)Data2Send, strlen(Data2Send));
driver.waitPacketSent();
}

float GetTempDS18() {
float NewTemp = 20.5;
return NewTemp;
}

float GetVoltage() {
float Tension = 5.00;
return Tension;
}

void setup() {

pinMode(CapteurTemp, INPUT_PULLUP);
pinMode(Bpy, INPUT_PULLUP);

if (SerialPrt) {
Serial.begin(115200);
Serial.println(" ");
Serial.print("Bpy : ");
Serial.println(digitalRead(Bpy));
}

if (digitalRead(Bpy) == false) {
//********* WiFiManager *********
WiFiManager wifiManager;
WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP
wifiManager.setConfigPortalTimeout(180);
wifiManager.autoConnect("xxx", "xxx");
//********* WiFiManager *********
} else {
// wifi_status_led_uninstall();
// WiFiMode(WIFI_STA);
WiFi.disconnect();
WiFi.mode(WIFI_OFF);
WiFi.forceSleepBegin();
delay(1);

driver.init();

if (SerialPrt) Serial.println("{\"Sync\":\"1ACFFC1D\",\"Module\":1,\"Temp\":" + String(GetTempDS18()) + ",\"Batt\":" + String(GetVoltage()) + "}");
Transmit("{\"Sync\":\"1ACFFC1D\",\"Module\":1,\"Temp\":" + String(GetTempDS18()) + ",\"Batt\":" + String(GetVoltage()) + "}");
ESP.deepSleep(Time2Sleep);
