Hi everyone, Now i try to connect my esp8266 to Blynk 2.0. After I upload the code, esp8266 do not show the same SSID name on the network. As you can see on the figure below, the correct SSID name is ‘‘Blynk Monitoring Energy Consumption-49F61’’, whereas show in network is ‘‘ESP-17D241’’.
Then i try to connect this network ‘‘ESP-17D241’’ in blynk app on my phone, but it fails.
I using Lolin new NodeMCU V3 microcontroller.
Here is my code.
// Fill-in information from your Blynk Template here
#define BLYNK_TEMPLATE_ID "TMPLZxyDHzLA"
#define BLYNK_DEVICE_NAME "Monitoring Energy Consumption"

EnergyMonitor emon1;
int PinA= A0; //sct pins
float Power;
double Current;
float Energy = 0;
float Voltage = 240;
double noise1 = 0.26; //0.26
double noise2 = 0.36; //0.36
unsigned long lastmillis=millis();
long prevMillis=0;
void setup()
{
Serial.begin(9600);
emon1.current(PinA, 100); // Current: input pin, calibration.
BlynkEdgent.begin();
delay (10000);
}
void loop()
{
if (millis()-prevMillis>15000) // Every 5 seconds it measure the current
{
Current = emon1.calcIrms(5000); // Calculate Irms only=1480
double calcurrent=Current*0.7071;
if (noise1<calcurrent<noise2)
{
calcurrent=0;
}
Serial.print(calcurrent,4); // Irms
Serial.println("A");
Power = calcurrent*Voltage;
Serial.print(Power,4);
Serial.println("W");// Apparent power
Energy = Energy + Power*(millis()-lastmillis)/36000000000.0;
Serial.print(Energy,5);
Serial.println("kwh");
lastmillis=millis();
prevMillis=millis();
Serial.println(" ");
Blynk.virtualWrite(V0,calcurrent);
Blynk.virtualWrite(V1,Power);
Blynk.virtualWrite(V2,Energy);
BlynkEdgent.run();
}
}
