why do we have a 6 hour limit?


Recommended Posts

Hi,

I need to execute several actions as close to solar noon as possible, which happens to be around 1 PM for my location in New Jersey. I was hoping to get the events scheduled with 7 or 8 hours after the sunrise of before sunset, but it looks like I am limited to 360 minutes. Is there a reason why we are limited to 360 min in the scheduling agent? My sunrise in the summer months could be as early as 5:30 AM and as late as 7:30 in the winter. While I can get very close to solar noon in the winter, in the summer I don't have a way to trigger something from a scheduler without any additional logic. So, for the months when my sunrise is at 5:30 AM I can schedule an action 6 hours after the sunrise, but instead of firing an action I can start a timer for 120 min before the action is triggered to get me closer to the solar noon. Is there any other way to implement this or the timer is my best option?

Thanks

Would this driver work?

Does not look like this driver offers any advantages over the existing C4 timer. Am I missing something?

Says countdown units can be in hours or days, so to me that seems like it could go greater than 6 hours if it can calculate days?  Says it can also trigger a specific time so maybe you could use solar noon

Can always email the creator of the driver and ask them

Just trying to follow, and my astronomy knowledge is far from complete so off the top of my head

-Solar noon is not directly related to sunset/sunrise times.

-Solar Noon times vary roughly  30 minutes within a year's range (disregarding DST)

-They vary roughly 5minutes within a month (disregarding DST)

-Year over year generally vary only a few minutes

 

If my above info is accurate, you're looking at a tough cookie to swallow for a C4 system.

Even if you could do xx hours after sunset beyond the current limit, I'm not sure how that would help you overly much.

 

 

You could do 6-12 scheduled events with a start and stop date (repeating daily) where you can 'set ' a time that is within an acceptable range of true Solar Noon

example Start date Jan 1 2022, end date March 5 2022, 12:30 repeat daily -> trigger Macro "SolarNoon"

Start date March 6 2022, end date May 1 2022, 13:35 repeat daily -> trigger Macro "SolarNoon"

etc etc  and program that several years ahead.

 

The date ranges could be longer or shorter depending on the 'acceptable range' from true Solar Noon.

 

 

Alternatively, if Google Calendar has (or there is a calendar maintained for it) solar noon by region that is within an acceptable distance, maybe this could help" https://drivercentral.io/platforms/control4-drivers/utility/schedule-it/

-Solar noon is not directly related to sunset/sunrise times.

It's not, but if you know both, solar noon is right in the middle. Sunrise = 6, Sunset =8, Solarnoon = 1 PM = (8PM - 6AM) = (14 H /2) = (7 H)  

-Solar Noon times vary roughly  30 minutes within a year's range (disregarding DST)
Depends on the region, but yes

-They vary roughly 5minutes within a month (disregarding DST)
More like 15min for us

I think doing a schedule for each month specifically and adding a delay may get me very close to the solar noon. Not sure if there any other way of getting this done?

This is a great driver and does allow for x hours (including 7, 8 etc) so solves the 6 hour limit.  It will not trigger at exactly solar noon though… You can have it count down days and trigger at a set time in the day (e.g. 12 noon).

For anyone looking for a big step up on the native Countdown experience button - this is it.

For anyone looking to calculate when solar noon is (or trigger an event at that precise time) you would need to look elsewhere at present although it would make sense for future enhancements to this driver to allow for specific times that are not specific time related (e.g. sunrise, sunset and solar noon).
