Created new documentation, since the old one was incorrect, so it should be ok now.

FYI: your code (this branch) saved my day.

I've tested it successfully yesterday on a xiao ESP32C3 together with a grove xiao shield and an AHT10 i2c temp & humidity i2c sensor for a terrarium project.

Note: that since the module is supposed to work with 5v but the xiao works with 3v3, I did splice the input usb power cable to bypass 5v to the relay module instead of the 3v3 from the Grove xiao shield. I suspect the i2c logic still works with 3v3, as the Xiao acts as the master and should be providing the voltage to the i2c data cables (in contrast to the VCC), but I'll report back in case I've fried up my board or sensors.
It may also work fine without the splicing (use 3v3 to power the relay toggling) but I didn't test that, and I'm not sure if this may harm the relay's working.

I’m it worked. Hopefully it will be included in the core of esphome.

The docs for this PR are also out of date and need to be looked at. Thanks
