I am fully expecting the answer here to be ‘no’ but is it possible to reset an input_* to the initial value defined in it’s configuration?
e.g
input_datetime:
my_time:
has_date: False
initial: 23:00
Is there a way to set the state of input_datetime.my_time to whatever was defined in initial?
what attributes does the device have in the states page?
Well, I looked into it and it doesn’t have a restore value stored in the attributes for you to build an automation off of. Luckily, it looks like a minor change to the input_datetime.py would rectify that.
Copy this file to the custom_components directory in your config. Name it input_datetime.py. It will overwrite what you got, but not it should have a new attribute named ‘initial’. You can use that to set the number back to the initial timestamp.
It’s a bandaide, but it should work. I haven’t tested this either btw… let me know if you have errors.

I just wondered if there might be a secret not-very-well-documented way to get the information seeing as HA must have known it at start-up.
I’m not being snarky, barely a day goes by here when I don’t learn about something that I am sure I have never seen documented. I reckon it is always worth asking.
Wow, thanks, I’ll give it a try.
Sorry but I get this at startup…

I think you may have messed up the copy/paste?
async_register_entity_service should occur at line 91, not 97. Is there some extra junk in the file?
I added a couple of lines of comments at the top between line 1 and 6 the ones with “”" to remind me why I am using the custom component.
I’m running v 0.76.1
(Waiting for some dust to settle on v0.77.x 
)
I’m not sure, it should be working. Might want to table this for a bit until I can look at it. I didn’t change anything in that section of code. I just added an attribute to the attributes, somewhere around line 187, if self.initial:.
Maybe this component cannot be overwritten?
just for shits and giggles, try to paste the code without adding comments.
Well, that is interesting, I took out the comments and it didn’t even attempt a restart. Maybe something is not copying across correctly…
I’ll try once more…

Sorry for the running commentary but hassio restarts slowwwwwly
Same error I’m afraid.
I’ll leave you to look at it at your leisure (or not if you choose not to).
But either way thanks for looking.
