Input_datetime history - potential bug?

Configuration
1

Hi everyone,

I’m using an input_datetime to store the last time of a motion sensor trigger (due to some unique requirements, this is likely the best way to implement it).

The action looks like this:

action:
- service: input_datetime.set_datetime
  data_template:
    timestamp: '{{ now().timestamp() }}'
  entity_id: input_datetime.my_motion_triggered_time

When i check the device history tab however, while there are correct entries for each update (when the change happened), every entry indicates "Changed to " and then the current date time. Whenever the automation is triggered, every entry is updated to the current date and time.

I suspect that the literal string '{{ now().timestamp() }}' is being put into the database, and then only evaluated on retrieval (in the history tab).

I want to write a PR, but would like confirmation that there isn’t just something wrong with my configuration.

I’m running core-2021.2.1 on HASSOS 5.10.

Thanks.

This looks like a bug in the frontend.

I did a quick test. I created a script that set an input_datetime just like you do. If I run the script I see that the service is called with the timestamp being a number resulting from the template being evaluated. And I see the input_datetime state changing accordingly.

Next, if I open the “more info” dialog for the input_datetime, I see the input_datetime.set_datetime service being called, twice, and the input_datetime’s state changing when it shouldn’t be!

Here is what happens when the script is run:

And, believe it or not, here is what happens when the “more info” window is opened on the input_datetime entity:

Yes it is a bug, yes it is being worked on

Link to report so I don’t write a duplicate?

It is a complex issue involving multiple bug reports and PRs in both frontend and core
