Microsoft Azure IoT edge

Just launched before IoT expo Amsterdam 2018 (19-20 June 2018), a brilliant approach by Microsoft Azure: embedding intelligence to the IoT devices (namely IoT edges), proposing containerized-driven devs-ops using all their SaaS, providing a public registry for massive involvement, and building a partnership with IoT hardware vendors. It’s a big ecosystem. Just get the deployment … Read moreMicrosoft Azure IoT edge

Edge embedded system: UP core

Hardware makers are competing to make a credit card-sized single board computer (SBC) that has ‘enough’ computing power on which ‘intelligence’ can be put. As an example, a drone that could take actions immediately when perceiving a certain pattern without beforehand coordinating with the ground station. Interestingly one of them is based on Eindhoven, UP … Read moreEdge embedded system: UP core

Sonoff RF Bridge (before the firmware flashed)

Turning a remote controller into a (WiFi) lamp switcher using a Sonoff RF bridge that converts a learned RF incoming signal to an MQTT publishing action. Sonoff original application is used (it needs to send the message to the Sonoff cloud). IFTTT (If-This-Then-That) is created to respond to an RF request to turn on a … Read moreSonoff RF Bridge (before the firmware flashed)

IoT market landscape

Many IoT vendors at the last IoT conference in Amsterdam (27-28 June 2018) prefer ZigBee as the connectivity protocol to RF or WiFi due to very low power and advanced functionalities. However, there are 2 main concerns: 1) it brings proprietaries to the market (must be connected to gateway from the same vendor); 2) the … Read moreIoT market landscape

Energy monitoring device

One of IoT application for the smart home: electronic appliance energy monitoring. I used Sonoff PoW as the measuring and switching device. To be integrated only into our private network, we need to flash the firmware. I used Tasmota’s ESP8266 firmware (https://github.com/arendst/Sonoff-Tasmota) and followed the instruction given in the web (Disclaimer: you have to solder … Read moreEnergy monitoring device

Integrating RF smoke sensors into Smart Home

Reflecting from the fire in the Office of Ministry of Transportation This is an industrial-grade smoke detector that sounds very noisy and transmits an “RF-433 MHz alarm” when exposing heavy smoke (e.g., in case of fire). I converted it to a network device using an MQTT-RF bridge, so:1) it can be monitored anywhere, anytime, and … Read moreIntegrating RF smoke sensors into Smart Home

Android sensors to Smart Home

Our Android phone is by default equipped with multiple sensors, e.g., accelerator sensors, magnetic field, photo light detector, noise level sensor, etc. I have an unused LG G4 which I turned into a sensor device. To convert the sensor readings into MQTT message, Sensor Node Pro is used. Telegraf is embedded to the MQTT server … Read moreAndroid sensors to Smart Home

InfluxDB cluster: Setup & Installation

In any good IT platform, main features must be prepared in front, by-design. Scalability and high availability are two must-have capabilities in any big data system today. Out-of-service, inaccessible, server busy, and too long response time are some issues that are avoided by any organization for years. Impressed by the performance of Influxdb compared to … Read moreInfluxDB cluster: Setup & Installation

Google G-Suite: Unlimited of everything

It is unbelievable, if you have a company, then you can have unlimited of everything from Google (email, storage, apps, etc.), only $10/user/month! …wars on “data collection”…
