Hi every body,

I’m new with Homey and I am struggling with the creation of a flow as simple clock programmer to turn on a light at 8:00 am and turn off this same light at 10:00pm.

I think it’s to simple for Homey…

I really need to create 2 or 3 flow to do this ?

Thank you very much for your help,

Have a nice day 🙂

If it´s always the same time, one flow will do it.

When:  
Time is 08:00

Then:  
One card with turn on device  
One card with turn off device with delay 7200s.

EDIT:  
Sorry, 7200s should be 50400s. Then it´s better to do two flows.

Better make 2 flows. From 8am to 10pm is 50400 seconds. Just 2 flows will do:  
WHEN time is 0800 THEN turn on.  
WHEN time is 2200 THEN turn off.

Ok I get it, thank you.

i’m just dissapointed by the logic of Flow. I have to learn and understand !
