Please read this project very carefully, do not send me any private messages. Please send your bid titled 'I Can Create An MQTT Broker Integrated With Postgre sql' We have a project that is an Emergency help call system for the elderly. It combines unique hardware developed by us that is both an IP Phone and an MQTT Client. Our central database on which the Asterisk PBX operates is in Postgre sql. We want to create an MQTT Broker on…

A scheme with a single process that acts as a broker will be used, providing the spatial and temporal decoupling offered by the message queuing systems. The broker will be in charge of managing the queues and storing the messages addressed to them. Thanks to spatial decoupling, the processes that use this system do not need to know or interact with each other, but will only communicate with the broker by referring to the name of the corresponding message queue.…

Ich habe so gut wie keine Ahnung von NB IoT und Azure-Cloud, deswegen brauche ich jemanden der mich dabei voll unterstützt. Ziel ist es die Daten von einem Device (Pumpe) in regelmäßigen Abständen (z.B. alle 10 min) in die Cloud zu schicken. Dort werden die Daten analysiert und bei bestimmten Schwellwertüberschreitungen spezielle Notifications abgesetzt. Später mehr Funktionen. Es geht darum Daten von einem Device (mit seriellen Schnittstelle RS232 oder RS485, Anfangs gerne auch nur ein mA-Signal) über dazugekaufte NB-IoT Box…

Due to lack of resources we need a strong python developer to finish customer project. Project is done in microservice approach with MQTT as broker, MinIO, InfluxDB as Storage, crossbar.iO as web-interface. Azure knowledge and C++ skills appreciated.

Necessito de programa que controle temperatura de 3 panelas com resistências. Para isso, será usado ESP32 que emitirá sinal PWM com o tamanho da largura do pulso sendo definida através de PID (proporcional integral derivativo). O programa deve conter a possibilidade de conectar 3 sensores onde o usuário poderá escolher entre PT-100 e DS18b20. O controle de temperatura seguirá estágios de controle das panelas, onde, após concluir o tempo e temperatura da primeira panela o programa começará a ativar a…

Basic features i need an android app where i will add several mqtt servers after adding a server i will add some devices under it each device type will have some predefined configuration like which topic to subscribe,which topic to publish and commands list for that device based on that it will add widgets under that device like buttons, display lables and progressbar etc. Advanced features i will add logics at runtime like i will select a device from dropdown…

i need to hide credentials on the browser page and also create many MQTT clients users for every user, so that i will set the credentials on the CPU of the IOT device. The second IDEA is to create a new client credential for every user, so if a hacker gets this credential will not be able to manage others clients or users. The issue is that if use F12 on any web-browser will show credentials on the page.
