Bedtime reports wrong temperature for my location.

Bedtime app reports temperature as 59 F when it wakes me up.

But I am at my other home near Taos NM, where my outside thermometer reports it is 31 F.

The temperature Bedtime reports seems to be for my primary home location, in Austin. A weather app matches the Bedtime-reported temperature to that location for the last week or so.

It is rather presumptuous of Apple to assume that I never sleep anywhere but my primary home, and this app creates a daily irritation when when it gratuitously presents this wrong information, and without saying what location it is using. 

I checked the feature page at Apple.com, and I could find no reference to changing the location.

But why should I need to change it?

I think that my phone has a GPS.

Those things know where my phone is (and presumably where I am, waiting to be awakened) to about the nearest 10 feet. 

Why report temperature at a fixed location, one where I am not, instead of actual location of the phone?

Is there a way for me to fix this, or should I wait for an update to the app or iOS?
