Description:

It is designed for a Bosch BME680 sensor connected with i²c and retrieves:

temperature humidity pressure AQI (pollution)

It sends notifications that can be handled by other modules and/or have its own display.

Disclaimer: AQI is quite approximative. It depends of internal sensor temperature (thus: updateInterval, gasLimitLow and gasLimitHigh must be tuned). AQI precision value may be enhanced using Bosh library if someone has motivation to look into).

Description:

MMM-NotifCustomActions is a technical module designed to do the glue between modules or do simple JS function.

It reacts on module notifications.

For example, it can send a specific notification to a module or execute a shell command when another module broadcasts a notification.

JS functions can be executed on browser side or on server side (ex: shutdown).
For simple JS code, all can be written in module config; for complex JS functions 2 specific files are automatically loaded and are accessible by the module.

Example of simple configuration

This example does:

a shutdown command (node side) when notification ACTION_SHUTDOWN is received. a sent of notification PAGE_SELECT with payload "musicPage" (client side) when notification SPOTIFY_CONNECTED is received. actions: [ { notification: "ACTION_SHUTDOWN", action_node: function(self, sender, payload) { exec("sudo shutdown -h now"); } }, { notification: "SPOTIFY_CONNECTED", action_client: function(self, sender, payload) { self.sendNotification("PAGE_SELECT", "musicPage"); } }, ] Download:

Description:

This module communicates with a IT8951 card to display MagicMirror² on a e-ink screen. It opens MagicMirror² page on a Chrome browser (with Puppeteer) and observes each DOM update. Periodically, the e-ink is fully refreshed and partially refreshed on DOM update.

Partial refresh is done in a flashy way by default (that is needed to support the 16 gray levels) but if image is only B/W (without gray), the refresh mode is changed to have a direct update without flash. Another way to have a fast refresh without flash is by adding the CSS class eink-4levels to a module. Thus, the refresh is forced to 4-level gray only.

The IT8951 is typically used by some Waveshare e-paper screens.

Sample of display with multiple modules:
d-screen-music.png
Each module’s area is individually updated when data changes.
All modules on 4 gray levels are updated seamlessly. Modules on 16 gray levels are updated with a flash area (here: the song cover).

Additional informations Force refresh by notification

A full refresh can be done by sending a notification IT8951_ASK_FULL_REFRESH.

Modules forced to 4 or 16 gray levels

To force gray levels, one need to add classes on modules in config file:

This class forces non flashy (but only on 4-levels gray) update of this module:

classes: "eink-4levels",

This class forces on 16-levels gray (but flashy) update of this module:

classes: "no-eink-4levels", Download:

@MajorC looks like this is a javascript change

@Matuki Also just wondering what version of nodejs you need and why? Just checking whether I need a new version of nodejs or if RPi distribution has caught up?
