Esphome Web 10C200 Modbus Register 3061: 43062 Supply flow to inside

Technical Definition

The register 43062 Supply flow to inside at address 3061 is used to monitor 43062 supply flow to inside on the Esphome Web 10C200.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit: kg/h
• 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 43062 Supply flow to inside (Address: 3061)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=3061, 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: "43062 Supply flow to inside"
  address: 3061
  value_type: U_WORD
  unit_of_measurement: "kg/h"

💡 Engineer's Insight

Analysis: Corresponds to the supply flow rate directed indoors. Units are typically m³/h or L/s. May be a redundant or different measurement scale.

Troubleshooting: Zero reading suggests a fan failure, obstruction, or damper closure in the indoor supply path. Verify airflow and mechanical components.
