kw alarm

[goku75]

I can not set kw alarm. Can you have an example of how to do this?

Hi. There is setPowerAlarm method. You can use it like this pzem.setPowerAlarm(ip, 20);

Maximum threshold is 22kW

[olehs]

btw, how are you going to use this alarm?

[goku75]

To communicate i used arduino mega. But now the only thing I care about is that it is when I overtake the 3 kw of absorption.

According to docs, PZEM's screen flashes when power is over threshold. But PZEM004T doesn't have a screen. This is why I wonder). But you can check power in your Arduino sketch by yourself.

There is a version with screen and it blinks indeed. There is also a place and pads for buzzer on the PCB inside, so maybe it can even make some noise )

I have the model with led screen and buzzer. I need the mega arduin program to set power-arm to 3 kw. Already I now read arduino values.

[goku75]

I use this to read the data:

include // Arduino IDE <1.6.6

include

PZEM004T pzem(10,11); // RX,TX IPAddress ip(192,168,1,1);

void setup() { Serial.begin(9600); Serial1.begin(9600); pzem.setAddress(ip); }

void loop() { float v = pzem.voltage(ip); if (v < 0.0) v = 0.0; Serial.print(v);Serial1.print("V; ");

float i = pzem.current(ip); if(i >= 0.0){ Serial1.print(i);Serial1.print("A; "); }

float p = pzem.power(ip); if(p >= 0.0){ Serial1.print(p);Serial1.print("W; "); }

float e = pzem.energy(ip); if(e >= 0.0){ Serial1.print(e);Serial1.print("Wh; "); }

Serial1.println();

// delay(1000); }

How do I enter this? pzem.setPowerAlarm(ip, 20);

for 3kw

[olehs]

add this at the end of setup() pzem.setPowerAlarm(ip, 3);

[goku75]

Ok it works, the display blinks exceeded the 3 kw but does not sound :( I'll check. thank you
