UPS battery backup saves the day…

only they are called pages instead of slides

pageTimeout: [ {pageNumber:x, timeout:nnnnn},....]

it is a more human thing…

either will work, index starting at 0, or slideNumber start at 1

I have updated the readme as well.

cd ~/MagicMirror/modules
rename current MMM-Carousel folder to something else

git clone https://github.com/sdetweil/MMM-Carousel

same config.js with one addition

new field

slideTimeout: [
   { index: 0, timeout:5*60*1000},   // this one is more than your transitionInterval
   { index: 12: timeout: 1*60*1000} // this one is less than  your transition interval
],

index starts at 0 for 1st slide in the slides list
you can override as many as you like with different settings for each

the timeout value is in milliseconds like the transitionInterval

if any slide’s index is not in the slideTimeout list,
then it gets the transitionInterval delay time

if you don’t add any slideTimeout entries, it just like the previous module…

the slideTimeout list does not have to be in any particular order

you said module, but you meant page.

       ["MMM-ImagesPhotos", "clock", "compliments"],

I only see one that that display images that I am aware of… and it has 3 modules.

I’m doing design in my head… trying
to figure out how it could work

longer, what would you do if it’s page is rolling out?,
so do you have an undeclared page in the rotation suddenly? , or does it extend the page time?
shorter, you want it to hide on its page before the page changes?
