Need a little help transforming DSL Rules to the new JSScript

Setup, Configuration and Use Scripts & Rules
17

I hope you don’t mind me writing your rule in JRuby

Things to note:

  • This is a fully file based rule, not GUI, so it includes the trigger and rule definition, not just the rule ‘body’
  • Don’t need to download the image as a file, then later on delete them (unless you want to keep the images?). Pushover lets you send the raw image (in memory)
  • Not using sleep. Instead we use a timer for fetching the snapshot from each camera, so the fetching runs in parallel
  • I haven’t tested this, so there may be some minor errors. I’d be happy to help further.
