input_datetime always triggers at the earliest setup time

[joagonca]

The problem

I use an input_datetime helper with only has_time: true to trigger an automation. The automation is successfully triggered, but always to the earliest time that the input_datetime was set.

Try (1):

1. Set input_datetime to 8:00
2. Automation triggers at 8:00

Try (2):

1. Set input_datetime to 7:30
2. Automation triggers at 7:30

Try (3):

1. Set input_datetime to 8:00
2. Automation triggers at 7:30

I think I ran into this exact same problem this morning. The weird part is I have had this automation active for a few months now and don't think I have run into it before. Maybe rebooting the server (which I do every few days on average for tweaks and updates) fixes the problem or something? Not sure. My guess is that it might be something to do with the time trigger not being notified of a change to the value of the helper.

I have tried to capture as much detail as I can, with both the actual state of the helper as well as the automation's trace and actual behavior. Hope this helps! Happy to try and answer questions to support.

Copied text from my post on Discord:

Hello! I have tried to find a similar problem to mine but have not (I may not know what to look for). I would like to see if anyone can help me understand my experience or agree that I may have found a bug to report. I am running 2024.5.3.

I have an automation that essentially acts as a wake-up alarm (turns on lights and opens blinds). It has worked well for me for months. This morning it woke me up at the wrong time and I am not sure why.

I have a datetime helper that I set to 0600 on weekdays and 0830 on weekends. This morning was supposed to be handled as a weekend, but it was triggered early. Looking at the history, the helper was correctly updated on Friday to 0830, so the automation should have triggered at that time on Saturday, but it triggered at 0600 instead, and the debug log indicates that it believed the value of the helper was 0600.

How did the automation trigger based on the previous time from the helper? (I have screenshots but Discord will not let me upload).

Thank you.
