# How to start a flow at a spesific time stored in variabel, with built in functions (Solution - Check every 60 minutes or use the app "Timey")

Hello,

Does anybody have a suggestion on how to start a flow based on a time stored in a Variable, without the use of “SunEvents” app or any other apps besides the built in functions? I also do not want to have a flow running “every 5 minutes” or so, to check if variabel match the system time.

My case is, my outside lighting is going on/off based on median-lux or using the built in “Sunset/Sunrise function”, but i wish to turn off the lights some hours in the middle of the night. My thought was to add a time to the Sunset time, and the Sunrise time that Homey stores, if the times overlap each other, then i will not turn of the lights.

I am using “SunEvents” for only two trigger-cards today, and that is the “Moon set” and “Nautical Dawn”, but i wish to reduce the Memory consumption and uninstall the app, but the built in “Time” card, does not support a variabel.  
I might got a App that can suite my needs, but not aware of it:

I also got a running RaspberryPi, if that one can be of some use to post a event of some kind, without the need of installing more apps on the HP.
