Hey guys,

I want to try to make my osmosis water system smart.
I bought this sensor to read water consumption, TDS and temperature data.

flowmeter
flowmeter1245×868 262 KB

As regards data consumption, I managed to configure the sensor.

Now I was trying to configure the temperature sensor which I then need to measure the TDS but I can’t get correct data.

I’m using an AZ-Delivery D1 Mini NodeMcu with ESP8266-12F CH340G Lua WLAN module

This is the tested configuration but the data is completely wrong

  -  platform:  ntc
     sensor:  resistance_sensor
     name:  NTC Temperature B Constant
     calibration:
      b_constant: 3950
      reference_temperature: 25°C
      reference_resistance: 50kOhm
  -  platform:  resistance
     id:  resistance_sensor
     sensor:  source_sensor
     configuration:  DOWNSTREAM
     resistor:  50kOhm
     name:  Resistance Sensor
     
  -  platform:  adc
     id:  source_sensor
     name: ADC Value
     filters:
       -  multiply: 3.3
     pin:  A0
     update_interval:  5s

Thanks for the support
