Cascading is achieved by connecting multiple NT18B07 modules in parallel on the same RS485 bus. Each unit must have a unique Node ID. Your host device will then poll each unit using its specific address to retrieve data. RS485 MODBUS-RTU Temp & Humidity Sensor | PDF

modbus: - name: NT18B07_Hub type: serial # ... configuration settings (baudrate: 9600, etc.) sensors: - name: "NT18B07 Channel 1 Temp" # ... other config settings address: 0 # CH1 register address scale: 0.1 # Shifts decimal point correctly unit_of_measurement: "°C" Use code with caution. Integrating with ESPHome Your host device will then poll each unit

The crucial lambda filter handles converting the 16-bit integer from the register into the actual temperature in Celsius. This config should be repeated for each of the 7 channels, incrementing the address for each one (CH2 address: 0x0001 , CH3: 0x0002 , etc.).
