Slow Raiser (for Aquariums)

Here is a small app that slowly raises the level of a dimmer, possible over an extended period of time, to a target level.

There was a typo, now fixed in this code. Re copy it if you haven’t found the typo already.

Hate when that happens :frowning:

Ya, it’s embarrassing!

Like you guys should be about:
No lock notifications or SHM support for Locks – very basic
Smart Lights blowing motion-off events
"Power Allowance" as a name for "Turn off after some minutes"
Smart Lights not having stand-alone “Turn off after motion stops”

Is there a way to use Rule Machine to kick this off at a specific time? Also, do you have a reverse of this app (start high dim down)?

Or maybe I should just ask has this been baked into RM and I missed it?

Not sure about making Rule Machine do this but there is a Slow dimmer here:

I’ve set this up to raise the level over an hour. But I’d like to cancel the slow Raise if the dimmer switch is manually adjusted. Any idea how to do that? Thanks!
