<![CDATA[M5sTACK ATOM LITE with PbHUB and sensors: how do I set this up for ESPHOME?]]>I have a M5sTACK ATOM LITE (https://docs.m5stack.com/#/en/core/atom_lite). Via the PbHUB (https://docs.m5stack.com/en/unit/pbhub AND https://github.com/m5stack/M5Stack/tree/master/examples/Unit/PbHUB) I connect the following sensors in this order into the ports of the PbHUB:
On CH0: TVOC/eCO2 (https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/Sensirion_Gas_Sensors_SGP30_Datasheet.pdf)
On CH1: ENV III (https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/enviii/QMP6988 Datasheet.pdf + https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/SHT3x_Datasheet_digital.pdf)
On CH2: DLight Unit (https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/hat/BH1750FVI).
On CH3: Microphone Unit (LM393) (https://docs.m5stack.com/en/unit/mic).

In the Home Assistant I have ESPHOME and the following YAML:

Have already tried a few things, but just do not get to the goal! Thanks for your help!

The PaHub (named after the 'Grove port A' I2C port in the M5Stack system) is an i2c expander. So if you have a bunch of i2c devices they can be plugged in and "polled" and read over a single i2c connection. The devices can even have the same i2c address, like having two ENV sensors, without conflict. Works very well. 'Polled' is where sensors are read one at a time and their value 'at that moment' is read and transmitted to the Atom
The PbHub (also polled) on the other hand connects to your controller the same way, i2c, but hosts almost any 'discrete' sensor like a switch or a lamp (GPIO, PWM, Servo control, ADC sampling, RGB light control) but remember that it has to squish the signals of all those devices into one i2c channel, so some very high speed devices may jitter. Very short signals such as an encoder blip could be missed altogether, periodically.

Thank you for the feedback. But how do I get all the sensors through the ATOM? PaHub? Or are there other possibilities?

PbHub is for digital I/O. (like switches)
It is not for I2C devices. (like ENVIII)

see here for a lead on using the hub
https://github.com/Chill-Division/M5Stack-ESPHome/blob/main/IO Hub 1 to 6 Expansion Unit (STM32F0).md
I would like to hire someone who can do integrations in esphome
