Nach ESPHome Update 2026.1.0 funktioniert der AHT10 nicht mehr

Hallo,

nach ESPHome Update 2026.1.0 funktioniert der AHT10 nicht mehr.

Fehlermeldung:

[17:46:25.415][C][aht10:157]: Address: 0x38 [17:46:25.415][E][aht10:159]: Communication failed [17:46:25.419][C][aht10:016]: Temperature 'Temperatur' [17:46:25.419][C][aht10:016]: State Class: 'measurement' [17:46:25.419][C][aht10:016]: Unit of Measurement: '°C' [17:46:25.419][C][aht10:016]: Accuracy Decimals: 2 [17:46:25.434][C][aht10:026]: Device Class: 'temperature' [17:46:25.434][C][aht10:016]: Humidity 'Luftfeuchtigkeit' [17:46:25.434][C][aht10:016]: State Class: 'measurement' [17:46:25.434][C][aht10:016]: Unit of Measurement: '%' [17:46:25.434][C][aht10:016]: Accuracy Decimals: 2 [17:46:25.449][C][aht10:026]: Device Class: 'humidity' [17:46:25.452][E][component:226]: aht10.sensor is marked FAILED: unspecified

kennt jemand das Problem und hat eine Lösung?

2

hier schon nachgesehen, ob es von den Änderungen betroffen ist?

3

danke für den Hinweis, hatte ich schon durchgeschaut, aber keine Hinweise gefunden

4

Was hast du als Framework? Arduino oder nichts eingetragen, so dass es nun auf esp-idf geändert wurde? Vielleicht macht das einen Unterschied

Das was metallmanu schon vorgeschlagen hatte:

setzt mal das framework dediziert auf arduino. Und den Code bitte hier im Forum in Code-Tags einfassen. Sonst kann das keiner vernünftig lesen.

Danke für eure Hilfe, der ESP8266 funktioniert nun, ob es an meiner Änderung “frequency: 100kHz” gelegen hat, keine Ahnung. Der 2. ESP funktioniert aber immer noch nicht, versuche mich mal durch die Neuerungen im Framework einzulesen, so ganz blicke ich das noch nicht. Hier der Code:

Sind das 2 unterschiedliche boards, also ein 8266 und ein esp32?

das hilft niemanden, was steht im Log?

ok danke, hier die Daten:

Danke für eure Hilfe, habe nun die Lösung gefunden mit variant: AHT20

  - platform: aht10
    variant: AHT20
    i2c_id: bus_a
13

He? Das war doch schon ewig so?

# AHT20 Temperature & Humidity Sensor/Compensation ENS160
  - platform: aht10
    variant: AHT20
    temperature:
      name: Temperature Calibration Sensor (AHT20)
      id: aht20_temp

Das minimum chip revision kann man so beheben.

esp32:
  board: esp32dev
  framework:
    type: esp-idf
    advanced:
      minimum_chip_revision: "3.1"

danke, habe ich auch schon entdeckt, man lernt immer dazu
