While brainstorming (daydreaming?) about what a graduation from apple and google would look like, I started wondering about how Apple Push Notification service (APNs) (not sure what the android equivalent is called) works behind the scenes. Perhaps something lite could be implemented with custom payloads over #xmpp or maybe it would need to be more of a custom service.
(I initially thought of #mqtt as a lighter coordination server, but persistence might be an issue there)

Latest #robot in sea trials. An old 12v trolling motor provides propulsion. A #RaspberryPi pico is always-on and runs the basics, sensors, h-bridges and such.

An RPi4 will be the main autonomy hub to enable detailed mapping and surveys and such. But for now I can just push #mqtt buttons in #HomeAssistant and move it around.

I built it almost totally out of scrap and epoxy. What a delightful waste of time!

P. S. Note the #lego crew on the bridge.

Now available: mysa2mqtt, a tool that bridges Mysa smart thermostats to MQTT, enabling integration with Home Assistant and other home automation platforms.

I haven't posted about my project MQTTy in a while, so here is a list of updates:

- MQTTy is available on Flathub.
- MQTTy is available on Windows 10/11 as a portable application, you can download it from the Releases page.
- Fully functional MQTT publisher.
- Missing "Subscriptions View" feature, I'm gonna start working on this one pretty soon.
- Missing "Workspaces" feature.

Oh wow, according to @codetrendr (account should start mirroring soon) #LavinMQ was trending on #GitHub two weeks ago?

For those who don't know: it's a #MessageQueue written in #CrystalLang supporting #AMQP 0-9-1 (like #RabbitMQ) and #MQTT (popular in #IoT).

And it was born at @84codes / #84codes.

Meshtastic - MeshCore - Reticulum: Warum Sideband (Reticulum) zurzeit meine №1 ist

Jedes der drei oben genannten (Mesh) Systeme hat sicherlich seine Vor- und seine Nachteile. Reticulum kombiniert allerdings einige der (mir!) wichtigen Funktionen:

Es legt einen großen Wert auf Sicherheit (Verschlüsselung). Wer also Messenger wie #Session, #Threema oder #Signal statt #WhatsApp bevorzugt, lieg mit Reticulum (Sideband) sicherlich auch nicht falsch.

Reticulum ist dezentral (!) und selbstorganisierend. Andere Mesh-Netzwerke, die neben der Funkanbindung (LoRa), noch Zugänge untereinander über einen #MQTT-Server anbieten, funktionieren nur, solange diese Server online und nicht überlastet sind. Sideband lässt sich auch ganz einfach über das Internet nutzen und wenn dies ausfallen sollte, gibt es ja auch noch

LoRa (Funk) Verbindungen für Not- und Krisensituationen. Es lassen sich so einfach und mit kostengünstiger Hardware lokale Netzwerke aufbauen.

Ob ich also an einem PC mit Interzugang sitze, oder mein Smartphone mit Mobilfunkanbindung (oder eben auch mit einem über Bluetooth verbundenen LoRa Device) nutze, ich bin dann Teil des Netzwerkes und kann auf all diesen Geräten erreicht werden und Nachrichten versenden.

Ich weiß jetzt nicht mehr genau, wer diese Frage eigentlich gestellt hatte, aber ich hoffe, diese Erklärung hilft weiter.

I highly recommend Mosquitto and MQTTX as #opensource options for #mqtt broker and GUI client. They are great for setting up and testing home #IoT networks! Both work with CA-signed or self-signed certificates for #TLS connections, which is imperative for better #CyberSecurity.

Hey #shelly owners, #homeassistant fans, #mqtt users, this one is for you.

Need to change the settings on your shellys, but in bulk because you have more than 50 of them?

Search no more. After some time with #chatgpt and my few skills in #python, this is the result, and it works :)

Raised an issue to discuss how to improve curl's MQTT message output.

https://github.com/curl/curl/issues/16633

Comments and insight requested to plan a possible PR as I can't see a way to fix it without it being a breaking change to current behaviour.

Throwing this question out there:

Is it possible to remap MQTT-messages from a certain IP (or user) to another one?

I only find documentation about remapping outgoing topics (bridge)

Fixing some last minute stuff for a new VerneMQ release :)
But first, enjoy your weekend, friends!
