It's Friday, friends. We've released VerneMQ 2.1.1 this week: https://github.com/vernemq/vernemq/releases/tag/2.1.1, packages and documentation upcoming.

Thank you for your support & have a fun weekend! :)
#MQTT #VerneMQ

Im Juni habe ich #Homeassistant als #Proxmox #VM aufgesetzt und nach und nach alle möglichen Geräte mittels #ModbusTCP (#Wechselrichter, #Speicher), #EVCC / #MQTT (#Wallbox), #Tasmota (#Stromzöhler) und #Zigbee (#Energiemessgeräte) integriert. Es schien kurzzeitig alles zu funktionieren bzw. hat auch funktioniert.
Allerdings - wie schon berichtet - war vor ein paar Tagen plötzlich der ganze Config-Ordner (/homeassistant) leer und damit alle #Daten weg.

Ich habe dann das Proxmox #Backup von vor dem Crash zurückgespielt und höndisch die seit dem Backup fehlenden Daten für den #Photovoltaik Ertrag ergänzt.

EVCC hat für die Wallbox eine Entität "sensor.evcc_loadpoint_warp3_total_charged_energy" erzeugt, die aber in HA selbst nicht für Statistiken nutzbar ist (sie wird nicht zur Auswahl angezeigt). Also habe ich eine #Hilfsentität angelegt:

template:
- sensor:
- name: geladene Energiemenge (gesamt) mit Einheit
unique_id: geladene_energiemenge_gesamt_mit_einheit
device_class: Energy
state_class: total_increasing
unit_of_measurement: "kWh"
state: "{{ states('sensor.evcc_loadpoint_warp3_total_charged_energy') | float(0) }}"

If you too would like your Claude Code agents to be able to send MQTT messages - I've got an MCP package for you:

Last time I tried adding #MQTT support inside the #proxmark3 client I failed and got memory crashes...

This time the story is different. #success

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:

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

Details at https://github.com/unixorn/ha-mqtt-discoverable/releases/tag/v0.20.0

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.

Released 0.19.2 of ha-mqtt-discoverable.

Fixes Select behavior (Thanks mhentschke!)

@homeassistant

Really need to replace my aging #MQTT broker with something new, in a container on my NAS.

From time to time it stops taking publish or even connects from a specific client as if it is blacklisting it. Sometimes a restart is all it takes, and sometimes (like now) I need to change the ID of the client because the broker banned the device for life.

I didn't know an MQTT broker had such functionality because I don't find any doc about such behaviour

Thank you for your continued support & interest in #VerneMQ. Have a good weekend, friends!
