Remote power control your IoT hardware and remote updating boot SD cards

Posted by jpluimers on 2020/07/16

Thomas Rini (of U-Boot and Yocto fame) mentioned these solutions for remote power control of IoT devices and remote updating SD cards in this slide State of the U-Boot – Thomas Rini, Konsulko Group:

Two power solutions I like myself are:

The combination of these allows for really flexible production and testing environments.

Node-RED

Posted by jpluimers on 2019/12/11

Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.

Seems one of the ways to automate our home: [WayBack] Node-RED, as it supports many input and output methods with all kinds of nodes between them:

input output
inject debug
catch
status
link link
mqtt mqtt
http http response
websocket websocket
tcp tcp
udp udp
serial serial

It is based on node.js, seems to need PM2 for running as a service, so I need to first figure out how well it runs on OpenSuSE (with more details than this gist).

After that I need to figure out how to version your configurations using git and document as it looks like the configurations sources are stored in JSON format [WayBack].

For resources:

  • StackOverflow node-red tag
  • Github node-red repositories
  • nodered documentation to:
    • get started (including Installation, Running, Adding non-stock Nodes, Upgrading, Creating your first and second flow, running on Docker / Windows)
      • running on a device (Raspberry Pi, BeagleBone Black, Android) which needs extra device specific modules to hardware inputs/outputs
      • communicating with a device (Arduino)
      • running in the cloud (IBM Bluemix, SenseTecnic FRED, Amazon Web Services, Microsoft Azure)
    • user guide (including Configuration, Security, Logging, Command-line Admin, Writing Functions, Embedding into an existing app)
    • cookbook (with many flows covering Basics, HTTP and MQTT)
    • creating nodes (with a wall of information: Creating your first node, JavaScript File, HTML File, Storing Context, Node properties, Node credentials, Node appearance, Node status, Configuration nodes, Help style guide, Packaging, Internationalisation)
    • flows (hundreds of them)

Code is published as JSON, but I wish more examples also showed the visual representation.

Via: [WayBack] Now I can go to bed :-) Added node-red [1] to my setup and thanks to node-red-contrib-ui [2] (replaced by node-red-dashboard [3]) I can now generate ni… – Jan Wildeboer – Google+ who also provided the large screenshot below.

Reminder to self [WayBack] Just a small FTR. Yes, the IKEA TRÅDFRI lamps [1] when equipped with Firmware >= 1.2.217 intergrate seamlessly into the Philips Hue system, thanks to t… – Jan Wildeboer – Google+:

  • IKEA lamps integrate with Philips Hue

  • IKEA lamps pair to the remote that you paired with the gateway before: no need to bring the lamp close to the gateway first
  • Philips tries the same

Repurposing Old Smartphones for Home Automation | Linux.com | The source for Linux information

Posted by jpluimers on 2019/03/13

Interesting read and watch:

At the recent Embedded Linux Conference and OpenIoT Summit, Mozilla Technical Evangelist Dietrich Ayala proposed a simple and affordable solution to home automation: A discarded smartphone can handle some of the most useful home automation tasks without requiring expensive hubs and sensors — or risking data security in the cloud.
