EMC2305 (2301-5) support PWM FAN contoller board

I would like to create a PWN FAN controller board using the EMC230x series (especially the EMC2305), D1 Mini Wemos (ESP8266) and ESPhome.
The EMC2305 is connected with I2C or SMbus to the ESP8266.
Sadly there is equal to zero material available on integrations with I2C.
Is there anybody capable and interested to help me with the code? The PCB design more or less done.
