How to send a notification

sdetweil

@alyx said in How to send a notification:

this.sendNotification(“PAGE_CHANGED”, payload);

you can only send notifications from the modulename.js

this notification goes to all running modules
it’s a broadcast

the page_changed is the notification string.
can be anything
payload is the data that goes w that notification Id. and can be anything

those receiving the notice MUST know what the format of payload is for and message they chose to process.all others would be ignored.

there are hundreds of notifications each minute.

Hi Sam,

My replies are getting flagged as spam apologies for the delay. But I think I found where the Selfie script sends out the notification. Do you think the other scripts I sent earlier are configured correctly?

@hango Hi Hango!

Ok so I’ll add that first line to my MMM-SelfieShoot.js (the module that needs to be actioned by another)

And the second will be inside the MMM-AlexaControl.js? I’ll test it now :)

Did it there but doesn’t seem to appear in Alexa, The other functions such as restart and monitor off/on works but I’m having trouble having this appear/ work.

@alyx so in alexacontrol, you have to create a notification device

notifications: [
    {
        name: 'Notificaition 1',
        port: 11100,
        OnOff: false,
        notification: ["NOTIFICATION", "PAYLOAD"]
    }
]

name is the thing Alexa will know
the tcp/ip port number to use for Alexa to contact this machine
and the notification info should look familiar

then u restart MagicMirror
( in the MagicMirror startup messages you should see a line listening on ??? where ??? is the port number you used in the notification entry)
and then Alexa discover devices

then whatever name is, should be discovered.

then you invoke it with
Alexa, turn on xxxx
where xxxx is the name of your device
(because alexacontrol creates fake wemo electric outlets)

note that notifications shown above is a list [], so each {} is a notification device

and this stuff goes in the alexacontrol module
config:{}
section

@sdetweil I have that set up al;ready but my alexa cant discover it for some reason. If you need you can see it in my config.js file above

sdetweil

@alyx nice, but you missed one key point

and this stuff goes in the alexacontrol module
config:{}
section

u have in the general module section not in the module config

Alyx

@sdetweil Ah! that worked thanks :) Next issue it doesnt call the module when activated lol

sdetweil

@alyx so, now open the developers window, ctrl-shift-i, and look at the console tab

u may be able to see some module report the notification

or install my samplemodule as it reports all notifications received
https://github.com/sdetweil/SampleModule

in the Alexa app u can control devices manually, so that makes testing a lot easier
