Errors in build when building yaml

ESPHome
1

Hi, quasi-nubie here (read: I don’t know what I don’t know),

I have a dht20-aht20 temperature sensor and trying to build the yaml file but I’m getting errors on the build. I know it’s got to be just ignorance on my part but I need a bit of help.

The “dht20-aht20-001.yaml”

esphome:
  name: dht20-aht20-001
  includes:
  - ahtx0.h
  libraries:
  - "https://github.com/adafruit/Adafruit_AHTX0/"
  - "Wire"
  
esp8266:
  board: esp01_1m
  
sensor:
  - platform: custom
    lambda: |-
      auto aht20 = new AHTX0Sensor();
      App.register_component(aht20);
      return {aht20->temperature_sensor, aht20->humidity_sensor};
    sensors:
    - name: "Temperature"
      unit_of_measurement: °F
      accuracy_decimals: 2
    - name: "Humidity"
      unit_of_measurement: "%"
      accuracy_decimals: 2

    AHTX0Sensor() : PollingComponent(15000) { }

    void setup() override {
      ESP_LOGCONFIG(TAG, "Setting up AHTX0Sensor...");
      if (!aht.begin()) {
        ESP_LOGCONFIG(TAG, "Failed to start AHTX0Sensor...");
      }
      LOG_SENSOR("  ", "Temperature", this->temperature_sensor);
      LOG_SENSOR("  ", "Humidity", this->humidity_sensor);
    }

    void update() override {
      sensors_event_t humidity, temp;
      aht.getEvent(&humidity, &temp);
      temperature_sensor->publish_state(temp.temperature);
      humidity_sensor->publish_state(humidity.relative_humidity);
    }
};

I assume that if you are a newbie, you got this config somewhere. Where?

You’ll see that https://github.com/adafruit/Adafruit_AHTX0 * Adafruit_BusIO is a dependency. So perhaps download that too.

That’s part of my confusion. I thought the library is referenced using " libraries:

Why does it find some and not the other?
