AHT-30 Temperature / Humidity Sensor Support (ESP32-S3-Box3 SENSOR-Dock)

[ChristophCaina]

Describe the problem you have/What new integration you would like The ESP32-S3-Box 3 comes with a Sensor-Docking Station. Part of this Station is an AHT30 Temperature and Humidity Sensor.

Based on the information I found, it is connected to the I2C of the Chip.

SCL = GPIO40 SDA = GPIO41

Please describe your use case for this integration and alternatives you've tried: I've tried to set the Sensor up with the platform AHT-10, but the Sensor value in HA remains UNKNOWN It seems, that the AHT-30 is not yet supported by ESPHome, and it is not working with "AHT10" platform. https://github.com/espressif/esp-box/blob/master/docs/hardware_overview/esp32_s3_box_3/hardware_overview_for_box_3.md

With this https://github.com/esphome/esphome/pull/5198 I am getting correct values from my dock sensors (setting variant: aht20)

I just wanted to link this PR since it is now in the official release... :)

@taylorfinnell: Are you using the S3-Box3 default VoiceAssistant Firmware?

If yes - might you share your config? Because I am getting errors when adding the I2C component and other custom sensors... :-(

Yea, this works or seems to at first glance.

Thanks :) Probably my issue was with the Bus then ^^ Will try it later

[EDIT] Thanks a lot - working fine 👍
