RemoteSign: {LM} command (Monochrome light)

Set a monochrome light channel brightness or start a light sequence pattern. The command can also be used to switch items on and off with the use of relays.

Syntax

{LM} ch ␑ action ␑ value1 ␑ value2

ch The channel to change.
action Perform some action on the light on channel ch. Available actions are:

Camera - simulates a camera flash gun
Coals - simulates glowing coals¹
On (good for relay connections)
Off (good for relay connections)
DOff (with incandescent fade)¹
Flames - simulates flickering flames¹
Flash - flash on and off
FlashR - flash on and off rapidly
Fluorescent - simulate the flickering start of a fluorescent light¹
Lighthouse - a repeating pattern of flashes¹ Note the difference between "Lighthouse" mode and "Seconds" mode is that the lighthouse mode performs a small ramp up and down of the light in an attempt to simulate a rotating beam.

value1 = duration of lighthouse light being ON in seconds
value2 = duration of lighthouse light being OFF in seconds

Lightning simulate lightning flashes and return brightness to original value
Minutes - switch on and off at intervals specified in minutes

value1 = minutes the light should be on
value2 = minutes the light should be off

mSecs - switch on and off at intervals specified in milliseconds

value1 = ms the light should be on
value2 = ms the light should be off

Phone - simulates a cell phone camera flash
RandomM - switch light on and off at random intervals

value1 = maximum minutes the light should be on
value2 = maximum minutes the light should be off

RandomS - switch light on and off at random intervals

value1 = maximum seconds the light should be on
value2 = maximum seconds the light should be off

Seconds - switch on and off at intervals specified in seconds

value1 = seconds the light should be on
value2 = seconds the light should be off

Slag - cooling slag (over 15 minutes)¹
Sunrise - simulate increasing brightness¹

value1 = number of minutes to transition to full brightness

Sunset - simulate decreasing brightness¹

value1 = number of minutes to transition to fully off

Toggle - toggle the light on or off
Transition from current brightness to a new brightness¹

value1 = brightness percentage from 0 to 100.
value2 = time in seconds to transition to the new setting

TV - simulates the changing light that lights up a room from a TV screen¹
Welder - simulate the light from an arc welder²

¹ Do not use with a relay as this effect uses pulse width modulation (PWM), use a MOSFET rather

² Ensure any relay you use can handle switching at 30ms intervals or use a MOSFET

Note that multiple independent light channels can be combined. For example, yellow and red could be combined with flames and glowing coal patterns in a campfire.
