DateTime Standalone Widget

A simple stand alone widget that presents an input field to select a date time. The widget supports a custom label and shows the current state of the DateTime Item in the footer. Clicking on the calendar icon opens the selection widget. Alternatively one can just type in the date. Clicking the check causes the new date time to be sent to the Item.

I am interested in working with dates in a custom widget but what happens to me is that when I press outside, the date is deleted and I would like it to remain present. I have seen the example of him, I have replicated it and it also happens.

Would you know any possible solution to this?


I get the following error when trying to add the “Date Time Standalone Widget”:

Running OH 3.3.0-SNAPSHOT on Win 10. No problem to add when running OH 3.2.0

For info, as I get inconsistent results depending on browser. I get that there’s not much control available for this…!

Dark theme used throughout.

Ubuntu, Firefox


Clicking on either dd, mm, or yyyy gives the below - no time picker. Clicking anywhere else provides nothing. After selecting a date, user has to manually enter a time before the check icon can be clicked, otherwise nothing happens.

Ubuntu, Chromium


The picker only comes up when clicking the almost invisible calendar icon, but at least you can choose the time! Picker doesn’t respect the theme settings.

Android, Chrome & Brave

Note the empty input field.

Tapping the input field provides this pop-up.

Tapping the check icon to accept the date time then clears the input field again, so it’s empty.

It’s interesting. I already realized that for the black background the calendar symbol is barely visible…

I have similar problem with iPhone/iOS.
Doesn’t work in openHAB app or edge browser on the phone.
The widget works fine on PC.
@rlkoshak do you know why?

I’m using the version from marketplace

Edge on iOS

openHAB app

There where some issues with setting time in the input card. This should be resolved with PR#1525. It will be available with the next milestone.
The datetime-local behaviour is not consistent across browsers. With the next milestone, you should be able to use datepicker as type and set a showTime flag to true. However, when using datetime-local, it should now correctly show time as well.

Thanks for letting me know

On iOS, no matter what browser you use, all browsers are forced to use the same renderer. So when you see differences in how things look, switching browsers on an iOS device isn’t going to help.

I do not know whether it is clear to everyone who reads this but I successfully used this widget with iOS and iPadOS based devices. openHAB 3.4.1.

Thanks a lot for it! Now I can dynamically set my alarm clock time in a convenient way!

Thanks for providing this! Is there a way to disable the time component, i.e., only show a date picker?

I don’t know. Try just date or date-local for the type field and see what happens.

date actually worked, thanks!

Am I missing something? Are the configuration options documented anywhere?

Sort of. When you create a widget through the “default x widget” metadata screen, under Type it says

Type of input (see f7 input docs or datepicker)

and under Input Mode it says

Type of data that might be entered (see MDN docs)

Which isn’t really used here but I include it for completeness.

There isn’t a link for “datepicker” but through trial and error I’ve found time works so assumed date would work too.

is it possible to change the format of the displayed datetime-value? I would like to have a format like “weekday, hh:mm”, which also shows the weekday

See Items | openHAB and Formatter (Java SE 17 & JDK 17).

Put the formatting you desire in the State Description metadata and change the widget to use =items[props.item].displyState.

However, be aware that you probably don’t want to do that for the placeholder. I’m pretty sure you’ll end up with a mess if you try to put it there. But it will work just fine in the footer.

Did I miss the solution for this problem (wrong display on iPhone) somewhere?

I have a similar problem on OH 4.0.4 stable.

I still having problem.
But I can change the value if the item already have value.
So to set the value first time you have to open OH GUI in web browser on your PC/MAC.
I also have set this item should restore when booted. So I don’t need to manually set the item after reboot.
