Add support for more sensors & basic Siren (switch) support

[iMicknl]

Added

• Added initial support for AirFlowSensor
• Added initial support for WaterDetectionSensor
• Added support for RainSensor
• Added support for CarButtonSensor
• Added basic support for Siren as switch
• Added support for MotionSensor
• Added support for SunSensor
• Added support for WindSensor
• Added all available states to device state attributes
• Added support for COSensor and CO2Sensor (AirSensor)

Changed

• Change 'battery_level' attribute to an integer, estimated based on the battery state
• Changed CO2Sensor device class to co2 to show as co2 sensor in HomeKit
• Remove tahoma_scene_oid, which is already used as unique_id for scenes

None of my comments are game changing. feel free to ignore if you disagree.

We should use f-strings here. I think this will be required for a merge in core.
f'{states.get(CORE_RELATIVE_HUMIDITY_STATE):%.2f}'

[iMicknl]

@tetienne do we need fstrings for all floats here? home-assistant/core#36258 (comment)

[tetienne]

What do you have in entry and what do you want in output?

To have a float from a string you can do:

>>>a = "2.3"
>>>float(a)
2.3

[vlebourl]

do we actually convert a float to string then to float?

[iMicknl]

To be honest, I am not sure how HA would like to have the values. Do they require a float or is a floating value in a string the right approach?

In the end, what should happen in sensor.py is that we make round the value and make it an int or float.

[tetienne]

@vlebourl, is states.get(CORE_RELATIVE_HUMIDITY_STATE) already a float? If a string, the round method can not be applied.

>>> a = "2.3"
>>> round(a, 2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: type str doesn't define __round__ method

[vlebourl]

I think it. otherwise we would get

>>> a = "2.3"
>>> "{:.2f}".format(a)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
ValueError: Unknown format code 'f' for object of type 'str'

And that's the signature for my temperature sensor:

Let's maybe leave this like this for now as this PR is already quite large, but resolve this in another PR once this one is merged

[iMicknl]

Agree, let's work on those improvements in separate smaller PR's. This one already got way to big :D

[tetienne]

Not related to the code, but I highly recommand you do only squash and merge your PR. You will have a nice commit history in the master branch without all your WIP and Fix commit of your branch.
Many projects do like this, HA included.

Makes sense. Especially since this PR doesn't include a nice commit log. 👍

You got it. You can allow only this method if you want in the settings of your repository.

[vlebourl]

Shall we merge?
