Issue with ENS160+AHT21 device.

onlize commented 7 months ago

The problem

I am trying to connect ENS160+AHT21 to WeMos D1 Mini (ESP8266). Here is the code that I use:

i2c:
  ## I²C Port - For Temp/Humidity/Pressure & CO²/VOC Sensors
  scl: D1
  sda: D2
  scan: true
  id: bus_a

sensor:
  - platform: aht10
    variant: AHT10
    temperature:
      name: "AHT10 ID Temperature Sensor"
      id: aht10_id_temperature_sensor
    humidity:
      name: "AHT10 Living Room Humidity"
      id: aht10_id_humidity_sensor
    update_interval: 60s
  - platform: ens160
    eco2:
      name: "ENS160 eCO2"
    tvoc:
      name: "ENS160 Total Volatile Organic Compounds"
    aqi:
      name: "ENS160 Air Quality Index"
      id: ens160_air_quality_index
    update_interval: 60s
    address: 0x53
    compensation:
      temperature: aht10_id_temperature_sensor
      humidity: aht10_id_humidity_sensor

I have this output:

Why am I getting all those messages about AHT10 sensor and what should I do about this?

I have same issue, identical code and either get zero readings (even after 1hr) or get a consistent value that doesnt change however the same sensor works perfectly fine when using Arduino....so this sort of narrows it down to an issue in ESPhome

I have an AHT21 that stopped working when upgrading to latest. Pinning the component to an older version "fixed" it for me, try this?

external_components:
  - source: github://esphome/esphome@2023.12.9
    components: [ aht10 ]

Also, @onlize, you need to set your variant to AHT20 if you're using an aht21 chip.

This does seem to be fixed in 2024.3.1

I am not able to test with 2024.3.1, but reverting to the older version of the component fixed it for me.
