[Feature] exclude keys per device model, or include keys selectively
**Problem description**

Some devices, such as smart plugs, have an integrated temperature sensor. This sensor is not meant to measure the _ambient temperature_, but instead can be used to warn when the device itself gets too hot.

Unfortunately, these sensors are exposed similarly to temperature sensors that _are_ actually meant to measure ambient temperature. This skews temperature data showing up in Home.app.

**Suggested solution**

While selectively excluding these sensors from individual devices is possible, it would be nice if there was a way to either (a) exclude them globally based on the device model, or (b) exclude them globally using the defaults object, and then enable them individually for actual temperature sensors.

**Describe alternatives you've considered**

Exclude them individually per device, but this is tedious, and requires continuous updating as new devices are added with non-ambient temperature sensors.

**Are you willing to contribute to this feature?**

Yes
