Organizing/ structuring rule sets and rules

[gwp1]

Three LIFX outdoor bulbs, call them #1, #2, #3.

The goal is to have the following outcome:

#1, color A
#2, color B
#3, color C
after 00:00:10, hard shift:
#1, color B
#2, color C
#3, color A
after 00:00:10, hard shift:
#1, color C
#2, color A
#3, color B
after 00:00:10, hard shift:
#1, color A
#2, color B
#3, color C

Visual being that the colors essentially move in a single direction across the house all night long.

I thought maybe cannibalizing Reactor Ex Machina until I realized I'm shifting COLORS, not ENTITIES.

Thoughts, anyone?

ok set a expression named rotated with value of ["a","b","c"] then set the expression to blank, the last value should be ["a","b","c"]
Then you use the expression variable to set your there colour lamps. the last reaction in the rule should be to set the expression variable to ${{push(rotated,shift(rotated))}} which will rotate the last value of the expression variable, removing the first value and placing it on the end.

This being my weak space, I'm missing how the COLOR setting gets tied to the expression here (admittedly pre-caffeine as I read what you wrote.)

[Elcid]

["a","b","c"] would hold the value of the colour setting. I do not own any lifx lamps, so do not know the value you would send. But a,b,c could be hex colour values or rgb colour array etc.

${{rotated[0]}} would be the colur of first lamp. ${{rotated[1]}} would be second etc

What does Lifx lamps require to be sent to change colour?

[gwp1]

It allows for a few options, I'm using RGB.

@gwp1 Whats the format?

[gwp1]

@elcid Red values 0-255
Green values 0-255
Blue values 0-255

I've built a small number of these just for those very basic "it's xmas, house is red and green" type times:

[Elcid]

[[255,0,0],[0,255,0],[0,0,255]] would be the initial array to set a starting value, instead of ["a","b","c"]
So red, green, blue for the 3 lights.
Then in light 1
red would be ${{rotated[0][0]}}
green would be ${{rotated[0][1]}}
blue would be ${{rotated[0][2]}}
For light 2 set the first index to [1] and for 3rd light to [2].

This would work for nth number of lights, you would just add an array element for each light.
