Pre requisiste

This article suppose you have a running nodered instance.

If you don’t have one yet have a look here first.

Goal

As a passionated programmer I need a reminder at `08:58` each working day (monday to friday)

That way if I am totally focussed on my coding session I still get a reminder.

Acceptance criteria:

  • A notification sound will be played in SONOS to remind me about it (audio effect)
    • This sound will be generated using ttsmp3.com free online tool
      • given text: Sir, the daily meeting starts in a few. Are you ready ?
      • voice: US English / Matthew
      • note: You can download the mp3 file here directly
  • A philips HUE effect will appear on my led strip (visual effect)

This way we have some fallback in the system and can reduce late joins of 99.9% :+1:

Implementation using NodeRed

In order to achieve that we will need two nodered extensions:

  • Sonos
  • Hue

Basically here we will have the following flow:

First we trigger this only at 08:58 during working days:

Warning

Node red will use the timezone defined in your instance. (If you run under docker you can define it via the env TZ=Europe/Paris or something else based on your region.)

(This concerns point 2) of the screenshot)

Then we trigger some actions

TO COMPLETE

Here is the snippet of code that you can import into node red directly:
