PZEM-003

This sensor works in the UART mode, and you should connect sensors to UART pins (e.g., for CC2530 P0.2 – RX, CC2530 P0.3 – TX). Therefore, you cannot use the UART interface in the same configuration.

PZEM-004 V3

Please note that the firmware supports V3 only.

PZEM-004 configuration for one sensor
PZEM-004 configuration for three sensors

This sensor type supports the write command on the corresponding endpoint and allows you to reset the counted energy.

write - resets the energy counter

Embedded description of outputs

When you prepare a configuration and save a firmware to HEX, Firmware Configurator stores a brief description of all some outputs in a proprietary Zigbee attribute. This description allows you to properly process and display GPIO outputs and analog values in your high-level system.

Please note, this description does not include information about values that the firmware sends using standard Zigbee clusters where a value format and units are described in the Zigbee specification (e.g., lightingColorCtrl, genLevelCtrl, msTemperatureMeasurement, msRelativeHumidity, msPressureMeasurement, msIlluminanceMeasurement).

If you create a custom converter in Firmware Configurator for your device and add it to your system (e.g., Zigbee2MQTT), you do not need this info because the necessary logic will be implemented in the created converter.

Cluster: GEN_BASIC (ID: 0)
Attribute ID: 32768 (0x8000)
Data type: Char String (ID: 0x42)

String format

One string contains information about all configured endpoints delimited by the “0x0D” character (ASCII CR).

The information of one endpoint is encoded as:

ABCCC[,DDD,[EEE]]

A – the endpoint number encoded as one hexadecimal character (‘0’..’9′, ‘A’..’F’).
B – value access rights encoded as one character:

  • R – the value can be read and reported.
  • W – write only.
  • r – report only.
  • * – read, write, report.

CCC – value ID. The firmware sends this ID in the “BASIC_DESCRIPTION” attribute with the corresponding analog value. If this value is empty, this endpoint and sensor on that endpoint has a single analog value (ID is not required). The firmware currently has the following standard IDs.

  • * – Generic GPIO output (On/Off).
  • # – Read only GPIO contact sensor. A subtype of the sensor is defined in DDD.
  • A – current.
  • V – voltage.
  • m – Altitude.
  • lx – Illuminance (lux).
  • W – Power.
  • Wh – Energy.
  • Hz – Frequency.
  • pf – Power factor.
  • ppm – air quality value.
  • ERR – error code.
  • 1-9 – any other value without a type (e.g., MODBUS data).

DDD – the optional value’s description (e.g., Voltage, Current, Counter).

The types of a contact sensor is defined as a single character:

  • c – contact.
  • g – gas.
  • n – noise detected.
  • o – occupancy.
  • p – presence.
  • m – smoke.
  • s – SOS.
  • t – tamper.
  • v – vibration.
  • w – water leak.

EEE – the optional analog value units encoded as a string (e.g., V, A, or lux).
