|
|
* --------------------
|
|
* Rawframe edit:
|
|
* - TESTED ON WLED VS.0.10.1 - WHERE ONLY PRESET 16 SAVES SEGMENTS - some macros may not be needed if this changes.
|
|
* - Code has been modified as my usage changed, as such it has poor use of functions vs if thens, but feel free to change it for me :)
|
|
*
|
|
* Edited to SWITCH between two lighting scenes/modes : STANDBY and HIGHLIGHT
|
|
*
|
|
* Usage:
|
|
* - Standby is the default mode and Highlight is activated when the PIR detects activity.
|
|
* - PIR delay now set to same value as Nightlight feature on boot but otherwise controlled as normal.
|
|
* - Standby and Highlight brightness can be set on the fly (default values set on boot via macros calling presets).
|
|
* - Macros are used to set Standby and Highlight states (macros can load saved presets etc).
|
|
*
|
|
* - Macro short button press = Highlight state default (used on boot only and sets default brightness).
|
|
* - Macro double button press = Standby state default (used on boot only and sets default brightness).
|
|
* - Macro long button press = Highlight state (after boot).
|
|
* - Macro 16 = Standby state (after boot).
|
|
*
|
|
* ! It is advised not to set 'Apply preset at boot' or a boot macro (that activates a preset) as we will call our own macros on boot.
|
|
*
|
|
* - When the strip is off before PIR activates the strip will return to off for Standby mode, and vice versa.
|
|
* - When the strip is turned off while in Highlight mode, it will return to standby mode. (This behaviour could be changed easily if for some reason you wanted the lights to go out when the pir is activated).
|
|
* - Macros can be chained so you could do almost anything, such as have standby mode also turn on the nightlight function with a new time delay.
|
|
*
|
|
* Segment Notes:
|
|
* - It's easier to save the segment selections in preset than apply via macro while we a limited to preset 16. (Ie, instead of selecting sections at the point of activating standby/highlight modes).
|
|
* - Because only preset 16 saves segments, for now we are having to use addiotional macros to control segments where they are involved. Macros can be chained so this works but it would be better if macros also accepted json-api commands. (Testing http api segement behaviour of SS with SB left me a little confused).
|
|
*
|
|
* Future:
|
|
* - Maybe a second timer/timetable that turns on/off standby mode also after set inactivity period / date & times. For now this can be achieved others ways so may not be worth eating more processing power.
|
|
*
|
|
* --------------------
|
|
*
|
|
* This usermod handles PIR sensor states.
|
|
* The strip will be switched on and the off timer will be resetted when the sensor goes HIGH.
|
|
* When the sensor state goes LOW, the off timer is started and when it expires, the strip is switched off.
|
|
*
|
|
*
|
|
* Usermods allow you to add own functionality to WLED more easily
|
|
* See: https://github.com/Aircoookie/WLED/wiki/Add-own-functionality
|
|
*
|
|
* v2 usermods are class inheritance based and can (but don't have to) implement more functions, each of them is shown in this example.
|
|
* Multiple v2 usermods can be added to one compilation easily.
|
|
*
|
|
* Creating a usermod:
|
|
* This file serves as an example. If you want to create a usermod, it is recommended to use usermod_v2_empty.h from the usermods folder as a template.
|
|
* Please remember to rename the class and file to a descriptive name.
|
|
* You may also use multiple .h and .cpp files.
|
|
*
|
|
* Using a usermod:
|
|
* 1. Copy the usermod into the sketch folder (same folder as wled00.ino)
|
|
* 2. Register the usermod by adding #include "usermod_filename.h" in the top and registerUsermod(new MyUsermodClass()) in the bottom of usermods_list.cpp
