ESPeasy library for Peacefair PZEM-004T-10A and PZEM-004T-100A v3.0 Energy monitor.
|
||||
(Based on Arduino communication library for Peacefair PZEM-004T-10A and PZEM-004T-100A v3.0 Energy monitor.)

***
|
||||
|

This module is an upgraded version of the PZEM-004T with frequency and power factor measurement features available at the usual places. It communicates using a TTL interface over a Modbus-RTU like communication protocol but is incompatible with the older [@olehs](https://github.com/olehs) library found here: [https://github.com/olehs/PZEM004T](https://github.com/olehs/PZEM004T). I would like to thank [@olehs](https://github.com/olehs) for the great library which inspired me to write this one.

### Manufacturer (optimistic) specifications
|
||||
|
||||
| Function | Measuring range | Resolution | Accuracy | TODO: Realistic specifications |
|
||||
|---------------|--------------------|-----------------|----------|--------------------------------|
|
||||
| Voltage | 80~260V | 0.1V | 0.5% | |
|
||||
| Current | 0\~10A or 0\~100A* | 0.01A or 0.02A* | 0.5% | |
|
||||
| Active power | 0\~2.3kW or 0\~23kW* | 0.1W | 0.5% | |
|
||||
| Active energy | 0~9999.99kWh | 1Wh | 0.5% | |
|
||||
| Frequency | 45~65Hz | 0.1Hz | 0.5% | |
|
||||
| Power factor | 0.00~1.00 | 0.01 | 1% | |
|
||||
|
||||
\* Using the external current transformer instead of the built in shunt
|
||||
|
||||
#### Other features
|
||||
* 247 unique programmable slave addresses
|
||||
* Enables multiple slaves to use the same Serial interface
|
||||
* Over power alarm
|
||||
* Energy counter reset
|
||||
* CRC16 checksum
|
||||
* Better, but not perfect mains isolation
|
||||
|
||||
### Example

```c++

#include <PZEM004Tv30.h>

PZEM004Tv30 pzem(&Serial3);

Serial.begin(115200);

Serial.print("Reset Energy");
|
||||
pzem.resetEnergy();
|
||||
|
||||
|
||||
Serial.print("Set address to 0x42");
|
||||
pzem.setAddress(0x42);
|
||||
}
|
||||
|
||||

|
||||
float volt = pzem.voltage();
|
||||
Serial.print("Voltage: ");
|

|

|

Serial.print("Current: ");
|

|

float powe = pzem.power();

|

|

Serial.print("Energy: ");
|

Serial.print("Frequency: ");

Serial.println(pf);
