.Quatt Sniffer Hp2 Modbus Register 2108: HP2 - Other bits R2108

Technical Definition

The register HP2 - Other bits R2108 at address 2108 is used to monitor hp2 - other bits r2108 on the .Quatt Sniffer Hp2.

• Protocol: Modbus RTU
• Data Type: INT16
• Unit:
• 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 HP2 - Other bits R2108 (Address: 2108)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=2108, 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: "HP2 - Other bits R2108"
  address: 2108
  value_type: INT16
  unit_of_measurement: ""

💡 Engineer's Insight

Analysis: A collection of various status bits for the HP2 unit. Interpretation depends on specific bit definitions.

Troubleshooting: A value of 0 means all associated bits are inactive. Analyze specific bit functions to diagnose. Consult device manual for bit map.
