- Make model exclude region for `iot` devices. This is consistent with `smart` and `smartcam` devices.
- Make region it's own attribute on `Device`.
- Ensure that devices consistently use `_get_device_info` static methods for all information relating to device models.
- Fix issue with firmware and hardware being the wrong way round for `smartcam` devices.
Python 3.11 ships with latest Debian Bookworm.
pypy is not that widely used with this library based on statistics. It could be added back when pypy supports python 3.11.
Mashumaro is faster and doesn't come with all versioning problems that
pydantic does.
A basic perf test deserializing all of our discovery results fixtures
shows mashumaro as being about 6 times faster deserializing dicts than
pydantic. It's much faster parsing from a json string but that's likely
because it uses orjson under the hood although that's not really our use
case at the moment.
