Technical Definition

The register name output effective Current at address 211 is used to monitor name output effective current on the Ex Esphome Web 64E0E5.

  • Protocol: Modbus RTU
  • Data Type: S WORD
  • Unit: A
  • Access: Read Only

How to Read (Python pymodbus)

Use this code snippet to read this specific value via RS485:

from pymodbus.client.sync import ModbusSerialClient

client = ModbusSerialClient(method='rtu', port='/dev/ttyUSB0', baudrate=9600)
client.connect()

# Read name output effective Current (Address: 211)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=211, count=2, unit=1)

if not result.isError():
    print(f"Raw Value: {result.registers}")
else:
    print("Error reading register")

client.close()

Integration (Home Assistant)

Paste this into your configuration.yaml:

- platform: modbus_controller
  name: "name output effective Current"
  address: 211
  value_type: S_WORD
  unit_of_measurement: "A"

💡 Engineer's Insight

Analysis: Represents the RMS current flowing through the AC output in Amperes (A). Shows the load current or energy export.

Troubleshooting: Zero suggests no load or no output. Low values could be a light load. High values might indicate an overload.
