I was just made aware of this #Android app to turn your phone into a simple #MQTT broker https://play.google.com/store/apps/details?id=in.naveens.mqttbroker
Just tried it out and it works :)

suggested to use an #MQTT broker at work for a clever way to notify some in-house services from our cloud services and it seems as they’re actually going that route and will have the contractor build a subscription module
It's been a while, but today I have mostly been playing with #python and #MQTT so I can see the battery charge level of my #enphase system on a #raspberrypi LCD display, via #homeassistant
If that sounds interesting to you, I documented the task here:

> 1751521309: New client connected from 192.168.2.41:52407 as 01003<ClientIDomitted> (p2, c1, k10, u'?SDK=C&Version=3.0.1').
YES! Maveo stick connected to my second mosquitto instance. Now how to forward that to HA's mosquitto....
Released v0.20.0 of the ha-mqtt-discoverable python module.
This is a pure-python library for creating #MQTT entities that will be automatically detected by #HomeAssistant
Added a 'set_blob' method to the Image class to allow publication of images directly from code. HA will take base64 encoded images directly via MQTT

Habt Ihr einen Tipp für eine #Wetterstation, die in #homeassistant z.B. #mqtt eingebunden werden kann?

48,3kWh bestehend aus drei
YIXIANG V2 DIY JK 200A BMS LifePO4 Metal Battery Case (https://szsyixiang.com/yixiang-v2-diy-jk-bms-lifepo4-metal-battery-case/)
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.

Moved away from EMQX for my home lab as they moved to a new licensing scheme and dropped features on the community version to #RabbitMQ 4.1.1.
After a day of working on it, got #oauth2 into the cluster working, and #ldap backed #mqtt client logins.
Not as flashy as EMQX, but fitting my needs so far very well.
Really wanted unified account management and doing it all through #Authentik through oauth2 and it's LDAP outpost is very cool. No more local mqtt accounts
@heiseonline Ich bin heilfroh über unsere Klimaanlage, die genau dann gebraucht wird, wenn die Sonne scheint und die PV-Anlage dem Strom dazu liefert. So viel braucht die auch nicht.
Der #homeassistant wird per #mqtt mit den Werten der PV-Anlage gefüttert und schaltet automatisch die Daikin-Klimaanlage ab, wenn der Akku unter 100% fällt.
Where do you put your IoT / smart devices within your home network?
Trying hard to trick this maveo connect stick into talking to HomeAssistant.
No third party access anymore.
App has cert-pinning I can't manage to get around.
Device speaks MQTTS, but no authentication, so can't integrate with Mosquitto.
It's some kind of Espressif device. Maybe I can read the FW?
(2) So ist für uns z.B. eigentlich auch eine Protokollfunktion wie sie wohl die #MySkodaApp bietet hilfreich, aber dann doch (noch?) nicht wichtig genug, diese Analyse zu ignorieren:
https://reports.exodus-privacy.eu.org/de/reports/cz.skodaauto.myskoda/latest/
Nach interessanten Abschnitten und Ladevorgängen kann ich auch die Daten vom Display (und aus den Lade-Abrechnungen) händisch erfassen. Leider müssen dazu alle Türen geschlossen sein, aber mit der App #LabLog geht es dann immerhin recht flott.
Praktisch ist dabei die direkte Anbindung via #mqtt die so die Daten direkt im #SmartHomeServer wie z.B. #HomeAssistant verfügbar macht...
...bzw. in unserem Fall (alles auf einem #RaspberryPi mit #bash Skripten selbst implementiert) ressourcenschonend über einen cloud broker mit einem simplen mosquitto_sub ... >> eautolog.jsonl.

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.
Successfully moved all my #MQTT connections onto the mosquitto server in my #homeassistant. Connections from solar panels via VPN connection on two AVM fritzbox routers, application my smartphone and a sensor on my electrical meter all publish in my local network now.

Wir haben einen #Roborock S5 Max, den ich vor dem ersten Einschalten zuerst gerootet und dann mit #valetudo versehen habe. Läuft seit sehr vielen Jahren ohne Verschleiß, ohne Defekt, ohne Probleme. Valetudo bietet #mqtt , das den Robi wiederum mit #homeassistant kommunizieren lässt. Dadurch kann ich tolle Sachen programmieren. Wenn es an der Haustüre klingelt macht er z.B. Pause. Wenn er Probleme hat, bekomme Ich eine Nachricht usw usf.
I'm kinda wondering.
If you use #MQTT over Websockets, how do you secure it?
Do you create a user on the broker for each user of your app? What would be the password, their password on the app? Or do you store MQTT keys in the database somehow?
