Clarify the patch / diff

[dcarosone]

Could you clarify the patch / diff / original revision this was copied from?

I'd like to apply this to my system, but I feel it's better done as a patch (applied via overlay as part of the nix packaging, in my case) so it doesn't stop any other fixes. It would also be more helpful as a submission upstream assuming it's correct for more than just this one device.

In the meantime, I've done the template workaround.

Hi, Thank you for your interest. In the original code, scaling was implemented as follows:

@property
def step_scaled(self) -> float:
    """Return the step scaled."""
    return self.step / (10**self.scale)

def scale_value(self, value: float | int) -> float:
    """Scale a value."""
    return value / (10**self.scale)

def scale_value_back(self, value: float | int) -> int:
    """Return raw value for scaled."""
    return int(value * (10**self.scale))

This code is from the original homeassistant/core -> tuya component base.py file. As you can see it here In my modification, scaling is fixed at 10:

@property
def step_scaled(self) -> float:
    """Return the step scaled."""
    return self.step / (10**1)

def scale_value(self, value: float | int) -> float:
    """Scale a value."""
    return value / (10**1)

def scale_value_back(self, value: float | int) -> int:
    """Return raw value for scaled."""
    return int(value * (10**1))

I wanted the most minimal modification to the code. Everything else is the same as the original. In my case everytime I manually set the scaling number it got overwritten after next update. I hope this helps. :D
