Today's IT project was to install an MQTT broker on my #SelfHosting #HomeLab. After a bit of shenanigans with DNS and certificates I've got it working. I'm using the Caddy proxy to generate me a certificate, and a shell script to copy the certificate to my docker host for use by the #Mosquitto #MQTT broker. My router and DNS server make sure the messages end up on the docker host, and a test application on my home desktop is able to subscribe and receive messages from the broker.

The real fun starts now... writing an app that receives my location data from #OwnTracks on my phone, stores it in a database, and ultimately does all sorts of pretty geospatial stuff.

Fallo en el backend de DJI dejó expuestos ~7.000 robots aspiradores en 20+ países: un ingeniero en Barcelona podía suscribirse por MQTT y ver cámaras, micrófonos y mapas del hogar. Ya está corregido. https://aidoo.news/noticia/Wljnzr

curl

Daniël Stenberg

facts and praise

I'm fortunate that I am allowed to follow Daniël, lead programmer of the mightycurl. The reason I formulated the line in this way, is because only through the power of the FediVerse I've gotten a boost from someone I follow, who found a post of the lead programmer or curl interesting

stats:

install base => 20000*106 devices

20 billion+ installations!

curl is used in command lines or scripts to transfer data. curl is also libcurl, used in:

cars
television sets
routers
printers
audio equipment
mobile phones
tablets
medical devices
settop boxes
computer games
media players

Curl is THE Internet transfer engine for countless software applications in over twenty billion installations!

curl is used daily by virtually every Internet-using human on the globe!

curl is 30 years old

Let that sink in!

Opinion

curl is mature critical network infrastructure software that we all need to have our internet powered software / hardware to function in respect to data transfer.

The syntax to use curl in simple implementations is IMHO quite easy. In case you need to know an extra option, the executable and libcurl have excellent documentation. End users normally interact with curl using the (elf) binary on Linux based POSIX operating systems. The more mature BSDs have another binary format

Just type curl to get an initial output which looks like this on my current system

curl
curl: try 'curl --help' or 'curl --manual' for more information

then type

curl --help
Usage: curl [options...] <url>
 -d, --data <data>           HTTP POST data
 -f, --fail                  Fail fast with no output on HTTP errors
 -h, --help <subject>        Get help for commands
 -o, --output <file>         Write to file instead of stdout
 -O, --remote-name           Write output to file named as remote file
 -i, --show-headers          Show response headers in output
 -s, --silent                Silent mode
 -T, --upload-file <file>    Transfer local FILE to destination
 -u, --user <user:password>  Server user and password
 -A, --user-agent <name>     Send User-Agent <name> to server
 -v, --verbose               Make the operation more talkative
 -V, --version               Show version number and quit

This is not the full help; this menu is split into categories.
Use "--help category" to get an overview of all categories, which are:
auth, connection, curl, deprecated, dns, file, ftp, global, http, imap, ldap, output, pop3, post, proxy, 
scp, sftp, smtp, ssh, telnet, tftp, timeout, tls, upload, verbose.
Use "--help all" to list all options
Use "--help [option]" to view documentation for a given option

When you type curl --manual|less you get the manpages which I delimited with less through a vertical pipe

          _   _ ____  _
      ___| | | |  _ \| |

NAME

    curl - transfer a URL

SYNOPSIS

    curl [options / URLs]

DESCRIPTION

    curl is a tool  for transferring data  from or to a  server using URLs.  It
    supports these protocols:  DICT, FILE,  FTP, FTPS,  GOPHER, GOPHERS,  HTTP,
    HTTPS, IMAP,  IMAPS, LDAP,  LDAPS, MQTT,  POP3, POP3S,  RTMP, RTMPS,  RTSP,
    SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.

    curl  is  powered  by  libcurl  for  all  transfer-related  features.   See
    libcurl(3) for details.

URL

    The URL syntax is  protocol-dependent. You find  a detailed description  in
    RFC 3986.

I can also type man curl to get a nice output:

curl(1)                                         curl Manual                                        curl(1)

NAME
       curl - transfer a URL

SYNOPSIS
       curl [options / URLs]

DESCRIPTION
       curl  is  a tool for transferring data from or to a server using URLs. It supports these protocols:
       DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT,  POP3,  POP3S,
       RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.

       curl is powered by libcurl for all transfer-related features. See libcurl(3) for details.

URL
       The URL syntax is protocol-dependent. You find a detailed description in RFC 3986.

       If  you provide a URL without a leading protocol:// scheme, curl guesses what protocol you want. It
       then defaults to HTTP but assumes others based on often-used hostname prefixes.  For  example,  for
       hostnames starting with "ftp."  curl assumes you want FTP.

       You  can specify any amount of URLs on the command line. They are fetched in a sequential manner in
       the specified order unless you use -Z, --parallel. You can specify command line  options  and  URLs
 Manual page curl(1) line 1 (press h for help or q to quit)

The reasoning behind curl --manual is simple. On a machine without the manual system you still need access to the full manual. This is one of the reasons why man curl is also implemented as curl --manual

An important RFC is echoed to my terminal in the man curl output which is RFC 3986

A Uniform Resource Identifier (URI) is a compact sequence of
characters that identifies an abstract or physical resource. This
specification defines the generic URI syntax and a process for
resolving URI references that might be in relative form, along with
guidelines and security considerations for the use of URIs on the
Internet. The URI syntax defines a grammar that is a superset of all
valid URIs, allowing an implementation to parse the common components
of a URI reference without knowing the scheme-specific requirements
of every possible identifier. This specification does not define a
generative grammar for URIs; that task is performed by the individual
specifications of each URI scheme.

I shall not quote the whole RFC 3986 here. You can read all about it on the RFC site (see sources)

As you can see curl is thorougly documented, has all the features a simple end user needs to fetch all kind of data, scaled up all the way to the extensive complex features router hardware et all, needs to transfer data.

programming route

I came to this toot when I saw that certain external feature code, which lives in stable external libraries, is now being removed from curl. I should say the code is depreciated then phased out.

This is a logical step

It takes resources to maintain external code
If the (shared) libraries are stable and mature, it's much better to just call those libraries and be done.
The more external code you can remove from your project the better it is for all the programmers

The same is also happening in the Linux kernel, they are following in the footsteps of curl

Conclusion

There is a treasure trove of information in the sources. Just reading the pages on RFC 3986 will keep you occupied for hours.
Have fun and keep reading / learning and programming!

Die Heizung (#DAIKIN Altherma 3 H HT ECH2O) an #HomeAssistant anbinden hat sich für uns gelohnt.

Mit meiner Zusatzregelung erreicht das ganze jetzt gravierend verbesserte Wirkungsgrade in der Übergangszeit. Bin gespannt ob das über die Heizperiode anhält.

Gateway ist ein #RaspberryPi Zero 2W mit PiCAN Zero mit anderem DC-DC-Wandler und extremer Konfiguration, damit ichs komplett am 24V / 30mA Raumthermostatanschluss betreiben kann.

Hah score! Managed to push data from #HomeAssistant to #MQTT using the MQTT Publish action in HA, then https://github.com/hikhvar/mqtt2prometheus picks it up and services it up to #Prometheus for use in queries. Will need to switch my #Keda scale object from a #RabbitMQ one to a Prometheus query. But will first let this metric sit there for a few days to make sure it behaves as expected.

ganz unglücklich bin ich leider nicht, ist ein erstes #mystrom device defekt.
(wifi plus; das sind nur smart plugs, keine messung).
Die firmware ist leider grauenhaft. Updates funktionieren (wenn es denn welche gibt) kaum ohne die Handy app. die devices befragen den DNS server beinahe all 5 sekunden nach der phone-home adresse (dass die geräte zum mittlerweile kostenpflichtigen cloud service verbinden will, lassen wir mal beiseite....). und den NTP Server, der im DHCP angeboten wird, wird auch ignoriert, weitere treffer auf port 123 auf der firewall :/
ich werde in zukunft wohl eher alternativen kaufen. z.b. bin ich mit den #hue smart plugs via #MQTT ganz zufrieden <3

Upgraded Home Assistant from 2026.2.2 to 2026.3.3 last night and it stopped reading the status of my zigbee devices via MQTT.

I'm running HAOS in a proxmox VM and zigbee2mqtt 2.1.1 in a docker container hosted in a different physical with a ConBee2 radio.

To check connectivity issues I had the integration listen for # and saw state updates for my zigbee sensors.

What finally fixed it was going into zigbee2mqtt's settings and disabling and re-enabling Home Assistant integration.

Um não tão novo post: do Blink para o controle remoto real — ESP32 + MQTT + Mosquitto local + app no celular.

O modelo pub/sub do MQTT encaixa bem em embarcados: o ESP32 não abre porta, não conhece o IP do cliente, só mantém conexão com o broker e reage a mensagens. O firmware fica event-driven, sem polling.

Documentei a arquitetura, o código completo em C com ESP-IDF, e os problemas que apareceram.
