This is a program for controlling my growlight for my plants. It has the option of two timers at 4 hrs or 8 hrs that will automatically turn it off if you want. Its all running on a Wemos D1 Mini what is stacked with a relay shield and a proto board that I have setup to drop the voltage from 12v(*from inside the light) to 5v for the board.
Something to note, CAYENNE_CONNECTED() and CAYENNE_DISCONNECTED() functions have to be enabled by modifying the cayenne library. Easy to do from other posts on here.
Will update pics of completed project in coming days.

Post the pics when you get a chance!

The Wemos D1 Mini and components are inside the light fixture so you don’t even see them. Will put up a couple more pics later today when I get the bulk of my plants under it
Updated code as I was having problems with the simpletimer library for some reason… this new way works better anyway.

Thanks for the update @vapor83 , love it!
-Benny
Hi, can you tell me how much time is your light on/off and how I can modify these values?
Thanks!
EDIT: I just saw that you have 4&8 hour timer.

@gaby_korupt this post may help you with your DHT11 code

@gaby_korupt This is how you change you timer duration. In the code below, there is a number that is added to millis() and that is the duration counting in millis(). So, you can change that number to anything you want you time to be. ((14400000/1000)/60)/60 = 4hrs. So 1 hr would be 1000(millis per second)*60(seconds in a minute)*60(minutes in a hour). You add the “L” to the number because that forces it to be a “long” so the number is calculated correctly.
Does that make sense or were you asking something else.
