Instead of modifying my original post. I will document the changes here. The big changes are that the module is not enabled until the button is pushed. This brings the battery life to whole new level. ESP-12F ESP8266 Wifi Board - ElectroDragon.

It can serve as either a server accepting incoming connections or a client making outgoing ones. The WiFiEsp library is very similar to the Arduino WiFi and Ethernet libraries, and many of the function calls are the same. Supports ESP SDK version 1.1.1 and above (AT version 0.25 and above).

And since only 1 set is needed at a time, only one DVR box is needed. So I used a 1-4 HDMI splitter/driver to distribute the signal from the one box to the 4 TVs. Using the attic pathway, direct connections were made to each of the sets. It was pleasing to see that the active HDMI splitter could drive the remote TVs without any pixelation or frame freezes. The furthest HDMI cable required 100 feet. The remote would only work when pointed directly at the DVR. Programming the ESP8266 (NodeMCU) with the Arduino IDE. Introduction This is an introductory article for those who already know the Arduino platform and are starting the programming the ESP8266 module through the NodeMCU platform or any other microcontroller of the same category.

Programming the ESP8266 (NodeMCU) with the Arduino IDE

The ESP8266 Module The ESP8266 module is a IoT device consisting of a 32-bit ARM microprocessor with support of WIFI network and built-in flash memory. ESP-12. With the ESP-12 modules on a breadboard adapter I was finally ready for some tinkering.

ESP-12

The plan for today was very simple: flash NodeMcu firmware, start programming the ESP8266 in Lua and try deep sleep mode. I put an ESP-12 on a breadboard, used a FTDI-ish thing to connect the ESP-12 to my Windows PC and used a 3.3/5V breadboard power supply (set to 3.3V) to power the ESP-12. Google Traduction.

Report the temperature with ESP8266 to MQTT - Home Assistant. I recently learned about the ESP8266, a $5 chip that includes WiFi and is Arduino compatible.

Report the temperature with ESP8266 to MQTT - Home Assistant

This means that all your DIY projects can now be done for a fraction of the price. For this tutorial, I’ll walk through how to get going with ESP8266, get the temperature and humidity and report it to MQTT where Home Asssistant can pick it up. Picture of the final setup (+ 2 LED for decoration) Home Assistant will keep track of historical values and allow you to integrate it into automation. Components I’ve been using Adafruit for my shopping: Besides this, you will need the usual hardware prototype equipment: a breadboard, some wires, soldering iron + wire, Serial USB cable. Connections. Meet the Arduino Killer: ESP8266. Advertisement Wi-Fi is an essential bit of kit for any Internet of Things (IoT) DIY projects, but our favorite Arduino doesn’t come with Wi-Fi, and adding in a Wi-Fi shield can bring the total cost to around $40.

Meet the Arduino Killer: ESP8266

What if I told you a there’s an Arduino-compatible dev board with built-in Wi-Fi for less than $10? Google Traduction. Arduino: Part 3.3: Arduino Uno + ESP8266 + Ecli...

As of this writing, we ship with NodeMCU 0.9.5 build 20150318 powered by Lua 5.1.4 but it may be more recent The Lua interpretter runs on the ESP8266 and you can type in commands and read out the results over serial. A serial console cable is perfect for this! Use either an FTDI cable or any console cable, you can use either 3V or 5V logic and power as there is level shifting on the RX pin. Nodemcu/nodemcu-devkit-v1.0 - GitHub. Internet des objets l'ESP8266 et ma porte de garage.

Dans ma maison, j'ai un garage dont la porte est motorisée ; avec une petite télécommande (433MHz) on peut l' ouvrir ou la fermer depuis la voiture, ce qui est bien pratique en hiver. Mais il y a deux problèmes : le premier c'est que la télécommande fonctionne aléatoirement (ce qui n'est pas pratique), le second c'est la sécurité du 433MHz. Ayant un Arduino UNO qui traîne dans un coin, ma maison étant domotisée (serveur fait-maison tournant sur du Python, du PHP, des scripts shell et le tout reposant sur xpl-perl) je me suis dit que le serveur domotique pourrait piloter la porte. Il peut déjà lire l'état de la porte du garage avec un capteur d'ouverture. ESP8266 Community Forum. Reducing ESP8266 Power Consumption using deep sleep. In my previous post, I mentioned that one of the reasons that I was excited about MQTT was because of its potential to allow power savings schemes on the ESP8266.

The MQTT broker could asynchronously hold messages during the period that the ESP8266 was in a sleep cycle, to ensure that nothing is missed while dramatically reducing average power consumption. This week I have hit a few obstacles, mainly due to the immaturity of current implementations of some of the latest MQTT qos (quality of service) features – at least that is what I suspect at this point. But more on that next week.

So, focusing on the ESP8266: my initial research had led me to believe that “deep sleep” mode was the way to go. Who can argue with using just 78μA during deep sleep? Arduino Ep.16 - Installation du module Wifi ESP8266. Arduino to ESP8266 By Serial Communication. Following on from the FTDI + ESP8266 post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino to talk to the ESP8266. I an using a 5V Arduino Nano which of course is 5V. The Esp8266 is a 3.3v device and so I am using a voltage divider to bring the Arduinos 5V down to 3.3v. If you are using a 3.3v Arduino then you do not need the voltage divider.

Arduino ESP8266 espressif iot. ESP8266 Community Forum. An inexpensive IoT enabler using ESP8266. A major component of or rather the very concept, Internet of Things, is about how to connect various devices to the network so that they can both send data and receive commands. Various technologies to address the last mile connectivity, such as bluetooth, wifi, NFC, etc... already exist, but most of these are complicated to deploy and often need additional hardware such as a local control server or appliance. In this instructable, I show you how to build and configure a simple standalone board that with the help of a wifi network can send environmental data to the internet and receive control commands to turn on/off a switch.
