Did anybody ever get this sensor working in esphome ?

I have tried the following that was posted on github but it just returns 65535 and never changes values

File: veml6070_custom_sensor.h

#include "esphome.h"
#include "Adafruit_VEML6070.h"


class VEML6070CustomSensor : public PollingComponent, public Sensor {
 public:
  Adafruit_VEML6070 uv = Adafruit_VEML6070();
  VEML6070CustomSensor() : PollingComponent(15000) {}
  void setup() override {
    Wire.begin();
    uv.begin(VEML6070_1_T);
  }
  void update() override {
    uint16_t cur_uv = uv.readUV();
    ESP_LOGD("custom", "The value of sensor is: %i", cur_uv);
    publish_state(cur_uv);
  }
};

Espconfig:

esphome:

  includes:
    - veml6070_custom_sensor.h
  libraries:

sensor:
  - platform: custom
    lambda: |-
      auto veml6070 = new VEML6070CustomSensor();
      App.register_component(veml6070);
      return {veml6070};
    sensors:
      name: "VEML6070 Custom Sensor"

The sensor i got is this one Sensor VEML6075 and on that page they state the library is the following “Library for sensor”

I have same situation If you find something let me know please, have a nice day…

Using the same code you have here and it is working without problem. the only difference I have is these

  board: nodemcuv2

i2c:
  sda: GPIO4

Hi,
Any update about this sensor, VEML6075.
I also got, like you, a reading of 65535.

What I saw that in the header you mention the VEML6075, but in the code there is mention of the VEML6070.

There are library for the VEML6075, see GitHub - adafruit/Adafruit_VEML6075: Adafruit Arduino library for the VEML6075 UV Sensor

The only problem for me is that no programmer, so to change the code that it works whit that library, I don’t now where to start.

Also the difference between the VEML6070 and the VEML6075 is that the VEML6075 has three sensors.
I think that is the reason that we get 65535

While trying to create my own code, stumbled on this where there the needed code for the veml6075. This use the libary from SparkFun_VEML6075_Arduino_Library

I got even the Index to show up.
