“…Querying a data for an existing topic, a PUBLISH message is sent from the publisher node to the broker which allows a publisher to write data on an existing topic or to create a particular topic if that does not exist in the broker yet. Also, a default node is allowed to create any topic within the broker [45] . The topic may be any electrical parameter (Line voltage, Line current, Energy, etc.)…”

“…The Broker is the major subsystem of the MQTT server that is primarily responsible for receiving all the messages. The Broker also allows a new device filtering the messages and publishing for all the subscribed clients [43] , [44] , [45] , [46] . There are several existing brokers among which Mosquito is one of the popular brokers that is being used in this work.…”

Highlights First time the solar-biogas-VRFB storage integrated IoT based smart microgrid is implemented. Optimized energy management has been demonstrated for the local community. Raspberry-Pi based low cost smart communication platform is used to monitor and control microgrid operation in real time. Available solar PV power is effectively utilized even during sudden grid outage at day time. 24 × 7 energy security is ensured by intelligent scheduling of RE sources and storage.

“…Adapun perangkat yang digunakan agar memungkinkan data diperoleh secara realtime adalah nodemcu esp8266. Perangkat ini banyak digunakan oleh beberapa penelitian berkaitan dengan teknologi IoT (pengukuran jarak, smart home, hidroponik, data gempa, dan lain lain) (Barai, 2017) (Kashyap, 2018) (Crisnapati, 2017). Alasan dipilihnya nodemcu esp8266 dari segi biaya tergolong low cost sehingga harga alat lebih terjangkau.…”

Perangkat IoT (Internet of Things) dapat membantu manusia dalam mengumpulkan berbagai informasi, termasuk menyimpulkan pola perilaku dengan bias semantik yang besar. Jaringan IoT memiliki kemampuan untuk menggunakan informasi yang diperoleh untuk melakukan manajemen pada dirinya sendiri ataupun perangkat lainnya. Salah satu pemanfaatan IoT adalah untuk mendapatkan informasi jumlah orang di tempat tertentu. Jika informasi ini dikombinasikan dengan yang lain, dapat membantu sistem berbasis IoT menemukan karakteristik lingkungannya. Dalam pengabdian ini, diusulkan penerapan penghitung jumlah pengunjung berbasis IoT. Penghitung jumlah pengunjung (VCS- Visitor Counter System) adalah alat yang digunakan untuk mengukur jumlah orang yang melintasi pintu masuk. Jika kita memerlukan informasi mengenai berapa jumlah orang yang ada pada suatu ruangan, maka hal ini bisa menjadi sebuah solusi sederhana. Penerapan alat ini bisa dugunakan pada toko ritel, event besar, gedung kantor, dan bangunan cerdas. Keuntungan penggunaan alat ini sebagai pemilik perusahaan yaitu dapat mendeteksi jumlah orang masuk dan keluar pada perusahaan tersebut, sehingga pemilik usaha dapat melakukan analisis dan membuat keputusan yang tepat berdasarkan data perhitungan yang dihasilkan. Riset ini dilakukan secara kerja sama terhadap sebuah perusahaan teknologi CV. Harmoni Permata. Sebagai sebuah Institusi pendidikan, kerjasama terhadap industri merupakan sebuah kegiatan yang harus dilakukan untuk hilirisasi produk agar menjadi sebuah produk komersial.

“…It is an extremely lightweight publish/subscribe messaging transport protocol that is useful for connections with low-power devices in remote locations where a small code footprint is required and/or where network bandwidth is at a premium [41]. MQTT protocol has been successfully used in wireless heart-rate monitors [42], remote healthcare sensors for use in biomedical applications [43], various IoT projects [44] and many existing commercial systems. Brood uses VerneMQ, which is a high-performance, distributed MQTT message broker [45] to handle incoming and outgoing MQTT messages.…”

This work demonstrates an open-source hardware and software platform for monitoring the performance of buildings, called Elemental, that is designed to provide data on indoor environmental quality, energy usage, HVAC operation, and other factors to its users. It combines: (i) custom printed circuit boards (PCBs) with RFM69 frequency shift keying (FSK) radio frequency (RF) transceivers for wireless sensors, control nodes, and USB gateway, (ii) a Raspberry Pi 3B with custom firmware acting as either a centralized or distributed backhaul, and (iii) a custom dockerized application for the backend called Brood that serves as the director software managing message brokering via Message Queuing Telemetry Transport (MQTT) protocol using VerneMQ, database storage using InfluxDB, and data visualization using Grafana. The platform is built around the idea of a private, secure, and open technology for the built environment. Among its many applications, the platform allows occupants to investigate anomalies in energy usage, environmental quality, and thermal performance via a comprehensive dashboard with rich querying capabilities. It also includes multiple frontends to view and analyze building activity data, which can be used directly in building controls or to provide recommendations on how to increase operational efficiency or improve operating conditions. Here, we demonstrate three distinct applications of the Elemental platform, including: (1) deployment in a research lab for long-term data collection and automated analysis, (2) use as a full-home energy and environmental monitoring solution, and (3) fault and anomaly detection and diagnostics of individual building systems at the zone-level. Through these applications we demonstrate that the platform allows easy and virtually unlimited datalogging, monitoring, and analysis of real-time sensor data with low setup costs. Low-power sensor nodes placed in abundance in a building can also provide precise and immediate fault-detection, allowing for tuning equipment for more efficient operation and faster maintenance during the lifetime of the building.
