Enumeration Type Documentation

Custom sensor attributes for PZEM-004T.

Enumerator
SENSOR_ATTR_PZEM004T_POWER_ALARM_THRESHOLD	Active power alarm threshold, in W.
SENSOR_ATTR_PZEM004T_MODBUS_RTU_ADDRESS	Modbus address of the device. Only set it with a single device connected to the bus.
SENSOR_ATTR_PZEM004T_ADDRESS_INST_SET	Modbus address the driver instance uses to reach the device. This does not change the address of the device itself.
SENSOR_ATTR_PZEM004T_RESET_ENERGY	Reset the energy counter of the device. Requires `CONFIG_PZEM004T_ENABLE_RESET_ENERGY`.

Custom sensor channels for PZEM-004T.

Enumerator
SENSOR_CHAN_PZEM004T_ENERGY	Active energy accumulated over time, in Wh.
SENSOR_CHAN_PZEM004T_POWER_FACTOR	Power factor, the ratio of real power to apparent power, with 0.01 resolution.
SENSOR_CHAN_PZEM004T_ALARM_STATUS	Alarm status: 0xFF when the active power is above the power alarm threshold, 0x00 otherwise.
SENSOR_CHAN_PZEM004T_POWER_ALARM_THRESHOLD	Active power alarm threshold, in W.
SENSOR_CHAN_PZEM004T_MODBUS_RTU_ADDRESS	Modbus address of the device. Only set it with a single device connected to the bus.
SENSOR_CHAN_PZEM004T_ADDRESS_INST_SET	Modbus address the driver instance uses to reach the device. This does not change the address of the device itself.
SENSOR_CHAN_PZEM004T_RESET_ENERGY	Reset the energy counter of the device. Requires `CONFIG_PZEM004T_ENABLE_RESET_ENERGY`.
