MQTT to HTTP Bridge written in Go. A lightweight service that subscribes to MQTT topics and forwards received messages to an HTTP endpoint.

Having much fun working on VerneMQ! :)

They wont let me take my own cables for field camping #why2025 ?
Its probably the missing #mqtt interface.

If you do #mqtt try this:

mosquitto_sub -F '@H::@S \e[92m%t \e[96m%p\e[0m' -h $host -t '#'

EDIT: all it does is prints a nice timestamp for each message and some basic coloring so you can tell the topic & payload apart.

ESP32-Faikin：開放原始碼的雲端控制Daiking空調模組
➤ 擺脫雲端束縛，輕鬆控制你的 Daikin 空調
✤ https://github.com/revk/ESP32-Faikin
ESP32-Faikin 是一個基於 ESP32 的模組，旨在提供本地控制 Daikin 空調，取代原廠不夠好且依賴雲端的控制方式。它提供網頁介面、MQTT 以及 HomeAssistant 整合，無需雲端連線，且速度更快。專案包含 PCB 設計，可在 Tindie、Amazon UK 和 eBay Australia 等平臺購買，並提供詳細的手冊和技術文件。
+ 原廠的雲端控制真的太慢了，這個專案太棒了，可以本地控制，還能整合 HomeAssistant！
+ PCB 設計公開，想自己動手做也可以，真是一個很棒的開源專案！

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! :)

#curl 8.15.0 has been released (#libcurl / #Haxx / #DICT / #FILE / #FTP / #FTPS / #Gopher / #HTTP / #HTTPS / #IMAP / #IMAPS / #LDAP / #LDAPS / #MQTT / #POP3 / #POP3S / #RTMP / #RTMPS / #RTSP / #SCP / #SFTP / #SMB / #SMBS / #SMTP / #SMTPS / #Telnet / #TFTP / #WebSocket / #SOCKS4 / #SOCKS5 / #SCRAM / #TLS / #HTTP2 / #HTTP3) https://curl.se/

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) }}"

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 :)

No último final de semana migrei o Mosquitto e o Zigbee2mqtt para meu cluster Kubernetes e neste quero migrar o Matter server. Isso vai fazer meu home assistant ficar menos sobrecarregado e deixar as coisas mais resilientes. #homeassistant #mqtt #z2m #matter

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:

New paper just published in Future Generation Computer Systems! We present and evaluate a method for activity detection in IoT, using domain-expert annotations of historical data and complex event processing.

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

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
