I would like to start a flow based on a tag with a time. The only trigger card available is a literal time, not a variable time. Plus there’s a gate-card (and) with a date, again a literal, not a variable. If we can trigger flows based on a time-tag and a date-tag, we can set the next start date/time in the flow. Thanks! ---

Could you perhaps give a concrete example? ---

I’m building a smart charging flow. For that, I check my calendar for the next appointment I need to go to. Plus I check energy prices to see when it’s cheap to charge (dynamic pricing contract). So then I need to start and stop charging based on the optimal start/stop time I calculate. If I can trigger a part of my flow based on that date/time, that makes it quite easy. I can use Chronograph with a timer but that’s a lot of extra hassle to calculate the duration of the timer. So for that reason I would like to fill a variable with a date and another with a time, then use the When trigger card “The time is…” with that time variable as tag, then use a And condition card “Today is…” with that date variable as tag. What’s available now is: ![Scherm­afbeelding 2026-09-29 om 16.58.28](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/8/881fb4b554d3641e1f2e01f5e851dde6b1a59989.png) Which is hard-coded, can’t change date or time in a flow. And what I want is (mockup): ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/e/ae7e82aa8b1aa3ebbd255a71188b4ba33f731693.png) Variable names, can change them in a flow and the date and time automatically change. ---

Check the “Timey” app, it has a triggercard which can use a variable as time input > [@\[APP\]\[Pro\] Timey - Make your time flows dynamic with variables](https://community.homey.app/t/app-pro-timey-make-your-time-flows-dynamic-with-variables/118139): > > Timey Use text variables in time flow cards with a 24-hour format: ‘H:mm’, ‘H.decimal’ or ‘H’ 00:00 is the earliest, 23:59 is the latest. Current version Stable: [1.5.0](https://homey.app/en-us/app/no.kjeet90.timey) Test: Why a own app for time flow cards? I wanted to set the time in one place and have it reflect in all my flows. The built in time flow cards does not support to set the time through variables, and the alarms did not have all the flow cards I needed. So I made a app which behaves like the built in time flow cards, just with… You can discuss with its developer if a date tag can be added to the app, which can be used in a conditional card. ---

Okay, understand. I agree with you that this should be possible using the standard Flow cards, so without any additional Homey apps.
