Is there a way to set up programs to adjust for DST (i.e., end/To 1 hour later when in DST)? I thought of using date ranges to determine DST, but a. it means programming for every year (since date ranges are specific to a year) and b. DST is a different date every year based on how Sundays fall on the calendar.

 

thx

I'm not certain I understand the question but ISY adjusts DST and can be found under "Configuration" Tab System/Clock in console.

My night on scene that is Sunset -10 minutes adjusted automatically when DST started.

I also have my time set by the NTP Server through the Internet. I don't know if that has any bearing on it.

Bump.

I was trying to do a program based on DST as well. Here's my scenario:

During the winter months sunset means it is dark. I want to activate a scene so my house is lit when I get home.

During DST when I get home it is light and I don't need those lights activated.

 

Any way to do the following?

If days are M-F and time is > 6:30pm and not day light savings time

Then turn on living room scene for 1 hour

 

Basically trying to mimic the ELK programming option of 'Is Dark outside'.

Thanks!

Hi iostream212,

 

The ISY can use Sunset but not DST.

 

If
       On Mon, Tue, Wed, Thu, Fri
       From    Sunset 
       To      Sunrise (next day)
   And Time is  6:30:00PM

Then
       Set Scene 'Living Room' On
       Wait  1 hour 
       Set Scene 'Living Room' Off

Else
  - No Actions - (To add one, press 'Action')

Like sub-routine, I use sunrise and sunset. One could also use motion sensors (with built-in light sensors) to transmit a signal when "dark" to trigger the lights to come on. I understand that weatherbug also includes a configurable dark parameter which could be used to trigger lights (requires the weatherbug module).

Hello guys,

Thanks for the ideas. I like both those thoughts and will probably use Sub-Routine's sub routine coupled with oberkc's idea for the motion sensor light sensor. Thanks!
