MMM-FrameLight

MMM-FrameLight

This is a MagicMirror² module for controlling an RGB-LED strip mounted onto or embedded into a smart mirror's frame. It can be used with the following input methods:

touch control (via IR touch frame or similar)
MagicMirror² system notifications (example use cases: voice control, home automation)

Demonstration

Installation and updating

This chapter shows how to install MMM-FrameLight and maintain it.

Installing the hardware

To use MMM-FrameLight, it is essential to have a WS2801 LED strip connected to the smart mirror device. Other types of LED strips are currently not supported. WS2801 is the default LED type of the module because some other types may block the onboard sound output of a Raspberry Pi (see here). This could lead to problems when using voice control or other sound related MagicMirror² modules. The LED strip should be mounted clockwise around the mirror.

There are a lot of good tutorials on how to connect the WS2801 LED strip to a device. Here are some links for the most common case (RaspberryPi):

NOTE: The links are listed to provide information about wiring the LED strip. The installation of the described software is not needed to use MMM-FrameLight.

WARNING: Be careful when working with electricity and double check the wires of the LED strip because the colors may be unintuitive. We - the module developers - are not responsible for any damage to you or your project.

Installing the module

The first software related step is to install some repositories used by MMM-FrameLight by following the links below and completing their installation steps.

After successfully installing the needed repositories, MMM-FrameLight can be installed by using these commands in a console / terminal (LXTerminal on Raspberry Pi):

cd ~/MagicMirror/modules                                  #adapt path to module folder if it is not the default folder
git clone https://github.com/RaspiManu/MMM-FrameLight
cd MMM-FrameLight
npm install

Updating the module

MMM-FrameLight can be updated / maintained by using git commands inside the module's folder. To update use the following commands:

cd ~/MagicMirror/modules/MMM-FrameLight                   #adapt path to module folder if it is not the default folder
git status                                                #optional step to check for changes before updating
git pull

If git pull leads to a message like “your local changes to the following files would be overwritten by merge”, you may have done local edits to the module's files. The local module files can be reset by using git reset --hard before using git pull. A backup of the old files is recommended in case some changes were on purpose (e.g. modifications to the module's look by editing the CSS file) and need to be restored after updating.

Configuration

This chapter is about the configuration of MMM-FrameLight to fit individual needs. It can be used with its basic functionality (touch controlled background light only), with advanced functionality (additional lighting effects on system notifications and party mode) or as a hidden module controlled by other modules (non-touch). Controlling the module via other modules can also be combined with touch input.

Basic touch configuration

The basic configuration of the module is focused on its core functionality as a touch controlled background light around the smart mirror. It can be configured this way by opening config/config.js inside the MagicMirror folder an adding the following to the modules: {} section:

{
	module: 'MMM-FrameLight',
	position: 'bottom_right',
	header: 'FrameLight',
	config: {
		LEDType: "WS2801",
		LEDCount: 160,
		Touchmode: true,
		ShowCaptions: true,
		ShowPartyMode: false,
		NightTimeActive: true,
		NightTimeStart: 22,
		NightTimeEnd: 6,
		NightTimeNotifications: false,
		Notifications: [],
		PartyMatrix: []
	}
},

The module's position can be defined according to the MagicMirror² documentation on module configuration. For aesthetic reasons, the options 'top_left', 'top_center', 'top_right', 'bottom_left', 'bottom_center' and 'bottom_right' are highly recommended. Using a header above the touch buttons is optional. It can be filled with any text (string, e.g. something in native language). The settings within config: {} work as described in the following table:

Parameter	Type	Description	Default	Options
LEDType	string	LED type of the strip used	"WS2801"	"WS2801" is only option at the moment (see "Installing the hardware")
LEDCount	integer	customization required number of LEDs of the strip used	160	any integer matching your LED strip
Touchmode	boolean	show module's graphical touch interface false will lead to module working hidden in background (requires "Non-touch configuration", see below)	true	true / false
ShowCaptions	boolean	show touch buttons' captions	true	true / false
ShowPartyMode	boolean	show party mode switch within settings menu (party mode requires "Advanced configuration", see below)	false	true / false
NightTimeActive	boolean	turn off lights when defined night time starts (no automatic restoring of state before night time after night time for safety reasons)	true	true / false
NightTimeStart	integer	time at which night time mode is activated	22	integers from 0 to 23
NightTimeEnd	integer	time at which night time mode is deactivated	6	integers from 0 to 23
NightTimeNotifications	boolean	show notification effects during night time (notification effects require "Advanced configuration", see below)	false	true / false
Notifications	array	array with custom effects on system notifications	[ ]	see "Advanced configuration"
PartyMatrix	array	array with a repeating sequence of custom effects	[ ]	see "Advanced configuration"

Advanced touch configuration

The advanced configuration of the module adds lighting effects to the basic configuration, which must be set up in advance. Those effects can be used as a reaction on system notifications and as party lighting. This subchapter describes how to define specific effects on system notifications and the effect loop for the party mode. It also provides a list of all effects and their configuration options.

WARNING: The following subchapter contains bright, flashing imagery that may cause discomfort and / or seizures for those with photosensitive epilepsy. Reader discretion is advised.

Effects on system notifications

There are a lot of options on what to realize with lighting effects on system notifications. Example use cases are visual feedback on touch gestures or indicating that another module shows new information. Effects on notifications are defined within Notifications: [] under config: {} analogous to this example:

Notifications: [{
	name: "ARTICLE_NEXT",
	effect: "BlinkColor",
	colors: ["rgb(0,255,0)"],
	options: [2, 0.5]
},
{
	name: "ARTICLE_PREVIOUS",
	effect: "BlinkColor",
	colors: ["rgb(255,0,0)"],
	options: [2, 0.5]
}],

Every definition inside Notifications: [] is surrounded by {}, separated by , and contains the name of the notification and the configuration of the effect to use as a reaction on it. For explanations on how to configure effects see "Effect configuration".

Party mode

Setting up a repeating sequence of custom effects for party mode is a great way of showing the smart mirror's LED lights to friends and family. ShowPartyMode: true is essential to be able to activate the party mode via touch input. The party mode sequence is defined within PartyMatrix: [] under config: {} analogous to this example:

PartyMatrix: [{
	effect: "RainbowCycle",
	colors: [],
	options: [2, 0.005]
},
{
	effect: "DockingTrains",
	colors: ["rgb(255, 0, 0)", "rgb(0, 255, 0)"],
	options: [2, 0.01, 20]
}]

Every lighting effect inside PartyMatrix: [] is surrounded by {} and separated by ,. For explanations on how to configure effects see "Effect configuration".

NOTE: While party mode is active, the party mode effect script runs in an infinite loop, which is stopped along with a correct shutdown of the MagicMirror² program or the system. In case of abrupt termination of the MagicMirror² program while party mode is active, control over the script is lost and the complete system must be restarted.

Effect configuration

The configuration of a lighting effect always consists of the three following lines of code:

effect: "",		//call effect by its name
colors: [],		//define colors used by effect
options: []		//set configuration options besides colors

colors and options are arrays whose contents are separated by ,.

MMM-FrameLight works with the RGB color format. Each color needs to be set like "rgb(255, 0, 0)" (string because of data transfer to Python). Dimmed colors or unlit segments of effects can be realized by increasing the amount of black in the color. The current background light color can be implemented into an effect via using "active color" instead of an RGB string as one of the colors. Doing so can lead to beautiful overlaying effects. The RGB values of the desired colors could be taken from the settings menu of the module (touch configuration only).

NOTE: Each effect has its own number of colors and options and all of them need to be set according to the effect list below (order of colors and options matters).

The following effects are currently available for selection:

Blink Color

This lighting effect is a simple blinking of the whole LED strip overlaying the currently used background light color (if background light is turned on) and can be set by using:

offset_start	options	7	how many single LEDs away from movement_start the effect will start	any number of LEDs	0

Special features: none

NOTE: To seamlessly implement the visualization of a touch input, using "active color" as color1 is highly recommended. When using movement_direction "both" with an even number of LEDs, movement_start has to be the right one of the two start LEDs. The option offset_start is mainly focused on bidirectional configurations and should normally be set to 0. An example for using offset_start is to configure a swipe move at the top and bottom of the frame (see GIF, middle height of one side is movement_start).

Non-touch configuration

The non-touch configuration of the module is focused on hiding it on mirrors without touch input and controlling it via MagicMirror² system notifications. This is realized by setting up the basic touch configuration with Touchmode: false. The control methods mentioned in this part of the documentation also work in combination with a configuration for touch input (basic or advanced). A complete non-touch configuration provides the full functionality of the module (for effects on system notifications and party mode see advanced touch configuration) with one exception: There is no touch interface to change the color presets. Therefore this must be done within color_presets.JSON. The file can be found inside the module's folder (subfolder presets). It can be modified via the GUI of the system used or with the following commands in a console / terminal (LXTerminal on Raspberry Pi):

cd ~/MagicMirror/modules/MMM-FrameLight/presets           #adapt path to module folder if it is not the default folder
nano color_presets.JSON

There are 10 presets inside of color_presets.JSON ("color0" to "color9"). Each of them is assigned an RGB value in string format, that can be customized (e. g. "rgb(255, 0, 0)", format important for data transfer to Python). After customization, the file must be saved (when using nano editor: press Ctrl + O to save and Ctrl + X to quit file).

NOTE: If the format of color_presets.JSON is corrupted, the file can be deleted manually. A subsequent restart of the MagicMirror² program will automatically recreate the file with default settings.

Controlling the module via MagicMirror² system notifications requires the use of additional modules, that are able to send such notifications. Examples for modules like this are MMM-Remote-Control by Jopyth (integrating MMM-FrameLight into home automations, examples below) and voice control modules in general (choose according to need for features). On smart mirrors with touch input it is also possible to visualize touch gestures using the Swipe Move effect with custom notifications defined inside the configuration of MMM-Touch by gfischershaw and MMM-FrameLight (s. advanced touch configuration). The following table lists the MagicMirror² system notifications, that can be used to control MMM-FrameLight:

Notification	Action
FRAMELIGHT_ON	turn on lights
FRAMELIGHT_OFF	turn off lights
FRAMELIGHT_PARTY_ON	turn on party mode
FRAMELIGHT_PARTY_OFF	turn off party mode and lights (fewer commands required to turn off)
FRAMELIGHT_PRESET	switch to another preset (requires `payload` with value 0 to 9)

The following examples show how to integrate MMM-FrameLight into home automations using cURL and the REST API of MMM-Remote-Control by Jopyth (must be set up in advance):

Notification without payload via GET method (adapt IP and notification to individual case):
```
curl -X GET http://IP.of.smart.mirror:8080/api/notification/FRAMELIGHT_ON
```

Notification with payload via POST method (adapt IP, notification and payload to individual case):

curl -X POST -H "Content-Type: application/json" -d "{\"preset\": 9}" http://IP.of.smart.mirror:8080/api/notification/FRAMELIGHT_PRESET

Contribution

The module can be extended by contributing own lighting effects via pull request. This chapter describes the necessary steps to do this.

Forking the module

The first step is to create a fork of MMM-FrameLight by pressing the corresponding button (upper right corner of Github page).
Implementing own effect code

The lighting effects of MMM-FrameLight are written in Python and can be found in the file "MMM-FrameLight_LED_Control.py". New lighting effects must be programmed to match the scheme of existing effects (basic structure, variables, parameter order,...) and have to be stored in the "Effects" section of the code. If unsuitable configuration of an effect can lead to a crash of the module, the code must have safety precautions to avoid it (cf. code of "Wobbling Segments" effect). Required helper functions shall be included in the "Helpers" section and shall not be redundant. The transfer of data from "node_helper.js" to the new lighting effect function inside the Python script is enabled by inserting a new elif case into the "start_effect" function.
Adding effect description

Since each effect has its own parameters, the order of which is crucial, it is essential to add a description of every new effect to the "Effect configuration" section of the "README.md" file. The scheme of the existing descriptions shall be adopted.
Creating a pull request

The last step is to create a pull request by pressing the "Compare & pull request" button (appears after first commit).
