Power Supplies on a programmable timer
« on: April 07, 2017, 11:12:50 AM »
My setup will be in place year round.  I have no problem keeping the Pi running 24/7 but it seems to me that I should cut power to the PS while they aren't in use.  I run multiple shows during the year and figure  I would like the PS to spool up 30mins or so before the show begins.  Anyone have any recommendations?  Id like the shows to run even when I am not home.  As an aside does anyone else find the verification letters almost impossible to get right on the first try?

I have programmable timers on mine and am doing exactly what I think you are asking.  (i.e. timer powers up 1 hour before show starts and about 30 minutes after show ends.)

I have all Falcon V2 controllers and have not had any problems with them powering up and down each night.  For the FPP's I use the Shutdown scripts found in the Script Repository.   I schedule the FPP to run the Shutdown script as the very last item in the last playlist of the night.  The Shutdown script does not power off the Pi, but it shutdown the OS so there will be no file corruption when the power gets cut via timer.

I think I understand that.....but how you power down the power supplies?  They would be constantly running.  I am looking for a inexpensive way to turn off the 120V supply to the power supply and have them power up 30 minutes before the show.  A 365 day programmable timer.

On the timer, what you need all depends on if you show is different on the weekend vers weekday. if its all the same or close then a 24 hour timer is fine. Just one thing to remember don't starve your power supplies. trying to run 6 power supply off one 15 amp on 14gauge wire just wont cut it. I run 2 timers each with double throw. meaning 1 timer will run 2 circuits.

 This is the ones I'm using  The pix does not match the description.  need a dpst  (Double Pole single throw)  with a 110 volt motor. 
If you need help on how to wire this up just let me know.

I guess I wasn't clear.  My outdoor 120v AC power is on programmable timers, so all power to the power supplies is cut off completely according to timed schedule.  I ALSO use the Shutdown Scripts on the Pi Players to shut down the OS before the timers actuall cut all power.

My timers are 7-day programmable so I can have longer show times on the weekends than on the weeknights. Not really sure why you would need a 365 day timer.

Well I plan on running multiple shows.......St Patty, July 1 , Halloween etc.  But I am not necessarily home to power on the PS.  Thus the 365 day timer. 

Plus.....if I am home I don't have to remember to turn it on!  lol

I will only be running 3 power supplies off a dedicated 15 Amp Circuit.  Timers I have looked at are industrial so will handle the load plus much more.  I was more looking if there was a cheaper or easier solution. 
 
I'm pretty new to all this so just putting my feelers out there to see if someone smarter than me has figured out something.

Thanks for your replies thus far guys!

They're such little draw when everything is sitting idle I don't know is if I would ever bother powering them down. To me it just seems like one more thing that can go wrong.
