Localization of Dates and Times with Flask-Moment

Previous post: Get started with Python Flask Framework on IBM Bluemix

Flask-Moment is an extension for Flask applications that integrates moment.js into Jinja2 templates. Flask-Moment is installed with pip
For locally:$ pip install flask-moment For Bluemix: In requirements.txt add: Flask-moment==0.5.1 In Initialize Flask-Moment from flask_moment import Moment moment= Moment(app) Add moment.js into base template base.html
In templates/base.html: Import moment.js library {% block scripts %}{{ super() }}{{ moment.include_moment() }}{% endblock %} To work with timestamps Flask-Moment makes a moment class available to templates. In passes a variable called current_time to the template for rendering.
In Add a datetime variable. from datetime import datetime @app.route('/')defindex():return render_template(

My latest publication: Environment monitoring system for agricultural application based on wireless sensor network

This paper proposes an Internet of Thing system architecture based on Wireless Sensor Network (WSN) for agricultural applications. The system consists of sensor nodes and a gateway, which allows a user to monitor environmental data for agriculture using a web browser. The sensor node is a microcontroller based Arduino including wireless module and connected sensors such as temperature, relative humidity, luminosity, air pressure and other sensors. A WiFi interface is deployed to exchange the environmental information from sensor nodes to the gateway running Linux. The gateway manages and transfers data to a Cloud where data were stored and visualized as graphs.

OpenHab2 - MQTT binding demo

OpenHab2 - MQTT binding demo This demo demonstrates how to use MQTT binding addon in OpenHAB2 installed into Orange Pi zero. The idea is very basic. A switch is created on default sitemap. When you turn on the switch, it sends "ON" message to Topic /office/light via MQTT broker that is installed on Orange Pi. When you turn off the switch, it sends "OFF" message to Topic /office/light. RequireOpenhab2 MQTT broker installed. First, install MQTT binding via paperui Define all the brokers which you want to connect to, in your services/mqtt.cfg file. cd /etc/openhab2/services sudo nano mqtt.cfg Edit the file as follow # # Define your MQTT broker connections here for usein the MQTT Binding or MQTT # Persistence bundles. Replace <broker> with an ID you choose. # # URL to the MQTT broker, e.g. tcp://localhost:1883or ssl://localhost:8883 mosquitto.url=tcp://localhost:1883 # Optional. Client id (max23 chars) tousewhen connecting to the broker. # Ifnot provided a defau…
