How to remove async_track_time_change object

Development
1

within the integration python code I create an object like

myobj = async_track_time_change(..............

how do I cancel/remove the async tracking object from firing??

setting myobj = None does nothing… the object still fires

You call the returned object, I.e. myobj().

perfect… thank you @postlund

I’d like to piggyback on that question:

While I can cancel the time tracking this way before the first time it fires, this doesn’t seem to work for me if it was executed at least once.
In my case I create a time tracker that I may cancel - if it fires, I get a notification. If I cancel it before the first notification, everything is fine, but if I get a notification, I get that notification every day at the same time, even if I cancel the time tracker.

Is that expected behavior? Can I still cancel the time tracking after the first execution?

Thanks.

Looks like I should be using async_track_point_in_time instead. But I still think I should be able to cancel an async_track_time_change after it fired.

I agree, you can create an issue in GitHub to initiate the discussion.

According to code pointer here (https://github.com/home-assistant/core/blob/9fd842825488d59aa4ccf6b805f1b828d72052aa/homeassistant/helpers/event.py#L1505) you have only reference to first incoming trigger and not consecutive ones.

Looking at the code, I feel like this should be working as expected. The returned unsub_pattern_time_change_listener calls the variable time_listener, which gets updated every time it fires …
