#AWS #IoT now has support for #MQTT 5: https://docs.aws.amazon.com/iot/latest/developerguide/mqtt.html#mqtt5 ... most notably are
- reason codes (the connection will now return an error code on disconnect)
- Maximum Packet Size can now be specified
- topic aliases (use 8 byte integer to identify a topic instead of a string)The last two are especially useful for #cellularIoT devices.

They connected the data collector to the rest of the system using #Tailscale to connect to their house and #MQTT (Mosquito) to transfer the actual data. It looks like Signal K supports MQTT directly and then sensor data from #Zigbee sensors are pulled in using #Zigbee2MQTT. I've done something similar on the Zigbee side and Z2M is super useful because it can handle intermittent connections, which I'm sure you run into on a boat more often than a house.

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. -

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

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.

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.

#MZBench will be a wonderful tool again for folks who need to do #MQTT load testing, writing scenarios in a Python-like scripting language. We'll need a better MQTT worker (current worker doesn't have v5), and maybe extend its configuration options towards scenario scripting. But even as is, this is a very powerful tool and a great sparring partner for #VerneMQ :)

und
48 EVE MB31 314Ah LiFePO4 Batteriezellen (gekauft bei YIXIANG)
Da ich alle Zellspannungen im Victronsystem haben möchte, um sie später via mqtt an homeassistant zu übergeben, werde ich die Batterien wohl über dbus-serialbattery (mr-manuel https://github.com/mr-manuel/venus-os_dbus-serialbattery) einlesen.

I am planning to open live datastream through my MQTT server to public. What kind of data that might be there?
1. Server Metrics
2. Router Metrics
3. IoT Metrics (The device is currently active, but unable to publish its data to MQTT server. Need more investigations). -
I’m looking for example code in #Forth (gforth) that is able to call a https REST API and return the resultant payload for further parsing. I’m currently doing a system call to curl with its output into a temp file I then read back in and parse. This would also be useful for future #MQTT work I have in mind. Sockets are builtin but TLS is not supported natively in #GForth that I can determine.
Any pointers to a pure Forth solution is welcome.
