Help with my first WebCoRE piston

#1

1) Give a description of the problem
This piston is supposed to turn on the undercabinet lights one hour before sunset and then turn them off at 11:00pm.

2) What is the expected behavior?
See above

3) What is happening/not happening?
The lights turned on an hour before sunset but did not turn off.

4) Post a Green Snapshot of the pistonimage

As a different option, I use a condition with a time is between comparison. For instance I have outdoor garage lights turn on when time is between 30 minutes before sunset and 10:35 PM, otherwise they turn off. I’m not able to access WebCoRE while at work, but I can post a screen shot this evening when at home.

Something like this.

But I want the lights to stay on until 11:00pm then turn off.

I modified your original piston and used the preset sunset values -1.

If this comment is for me, just change the sunrise part to 23:00.
But as you can see from the previous post, there are lots of ways to do the same thing with webCoRE.

We skinned this :cat: twice already… 7 to go lol.

There are multiple ways to go about this, but I think its important here for you to understand why your piston isn’t working.

Your root problem is that you only have one trigger, time happens daily at sunset -1 hour. That is the ONLY time that piston will ever evaluate. So every day, when that time happens, it’ll always run the if and never run the else.

Thanks @eibyer! That looks right. I had actually imported this from an example and changed the time off but it wasn’t working. I have a lot of CoRE pistons and I understand how that app works but this one takes a bit of getting used to. I am just trying to figure it out with little pistons first.

#10

Instead of importing your example, I redid my piston so that I could learn how webCoRE works. starting to get the hang of it.

#11

Here is the example I use for my outdoor garage lights. They turn on 30 minutes before sunset and turn off at 10:35 PM.

Just an observation and a bit of information for you.
You have used 30 minutes to ($sunset).
You do not have to use a variable. Adrian has defined some presets that you can use.

You may not want to use them but just thought I would pass on the information.

#13

Thanks! I did see that when I redid the piston.

#14

So this piston was working until the weekend. Then it stopped working for some reason. I didn’t change anything but the clocks went back this weekend. That shouldn’t effect the piston though because it is set to go one hour before sunset. Any ideas?

#15

There were issues with DST over the weekend.
Update Update all 4 elements of webCoRE to 0fd.
