UPDATE 7/9/2019: I put all my code on Github, as formatting here is messed up:
I regularly get requests for the latest version of this app: “Smart Light Timer, X minutes unless already on”, so I thought I’d post it to make it easier to find.
This app will listen for a variety of of triggers. When triggered, it will turn on a set of switches (or other actions), for a configurable amount of time. If more actions happens WHILE the lights are on, the timer will be extended. If switches are toggled off/on while the lights are in timer mode, the timer will STOP and the lights remain on. If the lights are already ON when the trigger happens, NO timer is started, and the lights simply stays on.
I use this extensively throughout my home, and it solves a bunch of problems that Smartthings could not be bothered solving in their standard app.
Hope this makes it easier to find. This version has been pending publication in Smartthings for 3 years, and is the newest version.
Cheers
Anders
/**
- Smart Timer
- Loosely based on “Light Follows Me”
- This prevent them from turning off when the timer expires, if they were already turned on
- If the switch is already on, if won’t be affected by the timer (Must be turned of manually)
- If the switch is toggled while in timeout-mode, it will remain on and ignore the timer (Must be turned of manually)
- The timeout perid begins when the contact is closed, or motion stops, so leaving a door open won’t start the timer until it’s closed.
