might be worth hardening the test transition value type to catch future changes from sending float.

https://github.com/home-assistant/core/blob/dev/tests/components/ozw/test_light.py#L34

>>> x = {'a': 0.0}
>>> y = {'a': 0}
>>> assert x == y  # false positive
>>> assert isinstance(x['a'], int)
Traceback (most recent call last):

AssertionError

Previous version of ozw values get converted to int already. I just forgot to int the fix for the new transition time.

[stshontikidis]

got it, actually added the assert I thought we were missing and you are right... tests still pass so that wont catch it. The instance version is less than the conditional so dropping into the if block that has the int

Change the light test to send a float as the transition instead of an integer. The sent value should still be an integer.
