Задача Цель - Написать программу которая подтягивает данные с WSS, подключение через MQTT, скрипт должен быть написан на NodeJS Обязательные требования чистый NodeJS в один скрипт, т.к. будет использоваться в нашей ограниченной среде разработки, бесперебойная работа скрипта.

Необходимо разработать устройство на основе модуля ESP8266 Либо ESP32, которое будет выполнять сбор данных с датчика расхода воды (импульсный выход) и датчика TDS (аналоговый выход), и дальнейшую передачу этих данных на сервер (MySQL, MQTT либо другое). Кроме того требуется передавать на сервер некоторые дополнительные технические параметры (MAC-адресс модуля, IP-адресс, имя WIFI сети, пароль используемой WIFI сети, напряжение питания, напряжение батареи, температура модуля). В разработку устройства входит: - выбор корпуса (желательно из доступных на рынке Украины); - разработка печатной платы, либо выбор готовых решений на основе предложенных модулей; - разработка програмной части (прошивки) модуля ESP; - разработка приложения для Android/IOS, либо веб версии. - изготовление тесто...

Здравствуйте, lis82! Я обратил внимание на ваш профиль и хотел бы предложить вам свой проект связанный с openwrt/mqtt. Мы можем обсудить детали в чате.

планируется куча устройств, которые через MQTT передают данные о своем состоянии на сервер, дальше все собранные данные надо визуализировать посредством WEB пользователям. данные – бинарные (да/нет), integer. данные собираются от разных датчиков. иногда в обратную сторону от сервера к устройствам тоже что-то может идти (редко) в идеале хочется сразу закрыть все вопросы, но обсуждается и закрытие частей. 1. написать сервис, запущенный на сервере, собирающий по протоколу MQTT данные и пищущий в БД 2. спроектировать БД для хранения собираемых данных 3. отобразить все объекты (стационарые) на интерактивной карте. т.е. при наведении на кратке на объект должно появляться окно с кратким состоянием объекта с возможностью перехода на полный статус объекта. карта ...

I am looking for a developer to create a website that can display real-time MQTT data through data visualization. The purpose of the project is to display real-time status information (such as temperature and power consumption) received from a population of 100s of remote embedded devices. Users will be able to securely log in and view the data for their own population of devices. They will also be able to send commands (such as reboot) to individual devices. In terms of programming languages and frameworks, I have no specific preference. Communication with remote devices will be using MQTT messages and so an MQTT broker will also have to be implemented along with a simple database to store the received data. The site will probably be hosted on Amazon (AWS). Addit...
