Welcome to the CoRE Logic Thread. Here you will find many community members that are more than willing to help you with the Logic and Programming of your Pistons. **There will be another thread for “How are you using CoRE?” and “How are you using the CoRE/AskAlexa integration?”. So, this is the p…

Quick question… its been ages since I first installed CoRE (v0.1…) , and now I’m looking to update to the latest version. Once I do that, will I need to re-recreate (ugh) or rebuild all my existing pistons? I’d like to think not, but wanted to confirm before taking the plunge.

[image] pcgirl65: It seems that CoRE looked at the first piston and turned the light on and started the countdown. Then it looked at the other piston and determined that the IF conditions weren’t TRUE but the BUT IF condition was TRUE so it turned off the light. I am thinking that this might h…

When you have a piston subscribed to a device, and the device status changes, the piston will evaluate again. I actually just did this with my bedroom and wake up pistons. Added a light in one that had already been in the other and it started turning off on me unexpectedly. I’m sure Jason will give…

Thanks guys! I appreciate the help and guidance. I was also trying to see how to incorporate it into one piston. The times make it more difficult. But this is why we like CoRE!:slight_smile:

Just goofing around with Core and see others are using the “when true” condition to perform actions. Can someone point me in the right direction to setup a sample piston? Thank you.

Yes, that is true. There are also samples here… http://thingsthataresmart.wiki/index.php?title=CoREsamples My understanding is that you can use a WHEN TRUE or a THEN in the same context. Sometimes using WHEN TRUE just to keep the piston shorter. Sometimes when there are multiple conditions a WHEN…

Oh Wow look at this! I have not seen this before. Thanks you so much, my weekend will be busy! Thanks everyone.

[image] pcgirl65: Sometimes when there are multiple conditions a WHEN TRUE may be used for one condition but not another condition. Exactly what I ended up doing–I have multiple OR conditions that need to trigger different things, depending on the conditions, so the “when true” actions live i…
