GE Range "User Temp Offset" being reported as a temperature instead of an offset. This displays weird when displayed as celsius.

Oven is set for an offset of 0 F. This value is a user configurable offset for any error in the reported temperature as displayed by the oven - eg, actual oven temp is 200f, but reported as 220, you would set the offset to -20 to have it report and regulate the temperature the corrected value). When HA is set to display in C, this shows that the offset is -18C.

The offset should be what ever value is reported as F*5/9 to show real offset in C. (ie. -20F offset would be -11.1C, 0F is 0C)

We do use F for our oven, but HA is set to C, and there is no to way I have found to make HA display only the oven in F.

Current reporting is confusing. Should the offset be set to an absolute value instead of a thermometer type?

I found out how to force the unit to F, so the display is now OK, but for those who use C, this is still an issue.

I can change units for the sensors, but not for the control.

I think that I have fixed the issue with things being wrong. The device should always be in fahrenheit internally (regardless of its display on the device), so I now force that to be the case. It will now align to the global setting in HA (so if you set HA to use metric, it'll now display correctly in Celsius).

I think this all relates to #344 and #248 as well.

I'm going to close this one and we can continue the conversation on #248 if not addressed in the latest commit.
