Reminder to self: get less dependent on the various clouds

Posted by jpluimers on 2021/06/04

For my link archive: [WayBack] Grote Google-storing trof Gmail, YouTube en diensten van derden – IT Pro – Nieuws – Tweakers.

It has some interesting tips for IoT video doorbell products that are less depending on single-choice clouds:

Er bestaan er minimaal eentje; smart deurbel met camera en evt speaker, eigen intern netwerk, compatible met SIP (en video), zelf verantwoordelijk voor opnamen, etc. Enige nadeel is dan wel de prijs, het is een Duits kwaliteitsproduct, dus reken rond de 350 euro voor het absolute basismodel. Doorbird heet het; oa te koop bij Robbshop en CoolBlue of direct bij de fabiraknt’s website.

Nee hoor, ze hebben een LAN API: https://www.doorbird.com/downloads/api_lan.pdf?rev=0.25

Je moet je huis flink geautomatiseerd hebben wil je echt nut van die api willen hebben.

als je alles zelf in de hand wil hebben doe je dat ook. Je zorgt er zelf voor dat je webinterface via een externe URL bereikbaar is en dan is het enkel je eigen hardware en internetverbindingen die als SPOF dienen en je kan dan ook makkelijker van solution-provider wisselen zonder vast te zitten.

Build your own Infrared reader head for electriciti smart meters for around USD 6: haus-automatisierung.com [4K] – YouTube

Posted by jpluimers on 2021/03/24

In German, but very interesting IR-Lesekopf für SmartMeter selber bauen | haus-automatisierung.com [4K] – YouTube:

I could not find the promised follow-up video at haus-automatisierung.com – YouTube, but the manual steps and the site below have enough information for me.

Too bad the site is way to big to fully archive in the WayBack machine. I only saved the top pages:

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.

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.

Accessing storage (NAS) over the Internet via FTP | FRITZ!Box 7490 | AVM International

Posted by jpluimers on 2019/02/13

Of course you don’t want this. So by the time you read this, the connection has been closed.

For testing some Internet of Shit stuff from a client that cannot do SFTP, I needed a temporary FTP accessible connection.

These links helped:

TL;DR:

  1. Preparing the USB stick:
    1. Ensure the USB disk is FAT/FAT32/NTFS
    2. Create a directory in the root of the USB disk for the FTP user (for now: FtpDirectory)
    3. Insert the USB disk in the Fritz!Box
  2. Logon to the Fritz!Box web UI
    1. Configure a user for FTP:
      1. In the menu, go to System, then FRITZ!Box Users
      2. Click Add user
      3. Name the user (for now: MyFtpUser)
      4. Ensure that user *only* has a checkmark for `Access to NAS contents`
      5. Click the button Add directory
      6. In the popup click Select folder
      7. Choose the FtpDirectory you just made
      8. Click OK
      9. Ensure the read and write checkboxes are enabled
      10. Click OK
    2. Configure the USB stick for FPT access
      1. In the menu, go to Home Network, then USB Devices
      2. Observe if the device is visible and has the correct file system (if not: ask AVM)
      3. In the menu, go to Internet, then Permit Access
      4. Click on the FRITZ!Box Services
      5. Ensure there is a checkmark at Internet access to your storage media via FTP/FTPS enabled
      6. At TCP Port for FTP/FTPS, fill in 21 (many IoT devices cannot use a different port)
      7. Ensure there is *no* checkmark at Allow only secure FTP connections (FTPS)
      8. Make a note of the value after FTP address (something like ftp://example.org:21`)
      9. Click Apply
  3. Test

SSH: Connection Reset by Peer – Server Fault

Posted by jpluimers on 2018/11/22

One occasion I had SSH throw a Connection Reset by Peer on my when was the SD-card of a Raspberry Pi started failing and the ext4 filesystem got mounted in read-only mode.

Then sshd was still listening on port 22, but since it could not write to disk any more, it threw a Connection Reset by Peer to the client.

It was on OpenSuSE Tumbleweed, but would failed just as well using Raspbian.

Lessons learned:

  • IoT hardware will fail.
  • ext4 breaks when the hardware breaks.
