* Bayesian Binary Sensor
Why:
* It would be beneficial to leverage various sensor outputs in a
Bayesian manner in order to sense more complex events.
This change addresses the need by:
* `BayesianBinarySensor` class in
`./homeassistant/components/binary_sensor/bayesian.py`
* Tests in `./tests/components/binary_sensor/test_bayesian.py`
Caveats:
This is my first time in this code-base. I did try to follow conventions
that I was able to find, but I'm sure there will be some issues to
straighten out.
* minor cleanup
* Address reviewer's comments
This change addresses the need by:
* Removing `CONF_SENSOR_CLASS` and its usage in `get_deprecated`.
* Make probability update function a static method, and use single `_`
to match project conventions.
* Address linter failures
* fix `device_class` declaration
* Address Comments
Why:
* Not validating config schema enough.
* Not following common practices for async initialization.
* Naive implementation of Bayes' rule.
This change addresses the need by:
* Improving config validation for observations.
* Moving initialization logic into `async_added_to_hass`.
* Re-configuring Bayesian updates to allow true P|Q usage.
* address linting issues
* Improve DRYness by adding `_update_current_obs` method
* update doc strings and ensure functions are set up properly for async
* Make only 1 state change handle
* fix style
* fix style part 2
* fix lint
