    Custom Alexa Skill in a Few Minutes Using Glitch
    https://hackaday.com/2018/01/17/an-alexa-skill-among-other-things-in-a-few-minutes/

    However, there is a very simple way to jump start an Alexa skill. I got one up and running in virtually no time using a website called Glitch. Glitch is a little bit of everything. It is a web hosting service, a programming IDE for Node.js, a code repository, and a few other things. The site is from the company that brought us Trello and helped to start Stack Overflow.

    Glitch isn’t about making Alexa skills. It is about creating web applications and services easily. However, that’s about 90% of the work involved in making an Alexa skill. You’ll need an account on Glitch and an Amazon developer’s account. Both are free, at least for what we want to accomplish. Glitch has some templates for Google Home, as well. I have both but decided to focus on Alexa, for no particular reason.

    Do You Need It?

    The first question you might ask yourself is do you even need an Alexa skill? I recently got Alexa to control my 3D printers by using IFTTT with no software development at all required. However, if you really want to claim you work with a virtual assistant, you are going to have to write some code somewhere.

    Glitch automatically sets up a library called Express in this project. It essentially is a simple Web server. Once you create the main app object, you can set up routes to have your code execute when someone calls a particular web service. It also includes an object that represents an Alexa service.

    On to Amazon

    Oddly enough, the next part is probably harder. From the front page of the Amazon developer’s site, you’ll want to select Alexa skills and then press the “Add a New” Skill button. A lot of the entries you’ll see have to do with more complex skills. Also, I’m not going to publish my skill, but it will still show up in my account. If you do some paperwork, you can submit your skill for testing with selected users or even publish it outright.

    Here’s a rundown of the fields you need to fill in on the Skill Information tab:

    Skill type = Custom Interaction Model
    Name = Whatever display name you like
    Invocation Name = This is what people will ask Alexa to use (e.g., “Alexa, tell Hacker Fact…” would mean my invocation name was Hacker Fact)

    In the Configuration tab, you can select HTTPS and then enter the URL from Glitch.

    On the next screen, you’ll want to pick “My development endpoint is a sub-domain of a domain that has a wildcard certificate from a certificate authority” because that’s how Glitch works.

    At this point, your skill should show up on any Alexa associated with your account (including Alexa apps like Reverb on your phone). You can also do tests here in the console to see if things work.

    This is enough to get your code working with your Alexa.

    Of course, you could set up your own server to do all the things that Glitch is doing for you — maybe even on a Raspberry Pi. You can also let Amazon host your code as a Lambda function

    Wifi Outlet Hacking
    https://hackaday.io/project/20316-wifi-outlet-hacking

    Cheap Chinese wifi switches that turn out to be quite hackable

    Never was thrilled with the app that it required, so I went about reverse engineering it..

    After taking it apart (1 screw and snapping it open) it turns out it has a cheap esp-8266 microcontroller wifi module ( the esp-12F to be exact).

    I will update the documentation as I get more figured out.

    Looking at the design and the 2 different brands I have looked at it looks like these, like most chinese consumer products are probably just rebrands of the same product.

    Managed to whip up a programming jig with some wire, bread board, pin headers, plastic and some hot glue.

    Comments:

    I can recommend the sc20 series of esp8266 based switches itead makes.

    “Question: Does it work with Alexa dot?

    Answer: Revising answer below to YES!!! Download the Tuya Smart App instead of the UCSmart App on the directions. With the Tuya Smart app you can then pair with Echo Dot (Alexa). Just did mine.

    Connect Your ESP8266 to Any Available WiFi Network

    Establish an Access Point that connects your ESP8266 module to any network making a universal firmware that can be used anywhere.

    Regardless of the IoT application you’ve developed, when using the ESP8266, you must set the WiFi credentials into the ESP8266′s firmware to establish the required connections and be able to send data to the cloud. This is one way to connect, but you can also build your own access point into the board making an universal firmware which will establish a connection in any network available just by pressing a button.

    This open-source LTE shield uses SIMCOM’s SIM7000-series modules with the latest LTE CAT-M technology to allow Arduino users to painlessly connect their low-power IoT devices with the next-generation cellular technology! NB-IoT is also available for many countries (but sadly not in the USA yet) simply by swapping out to a different SIM7000 module version. Luckily SIMCOM made it super easy to integrate this module because most of the AT commands are identical to previous version, and Adafruit has a wonderful library for their FONA 2G and 3G products.

    How Low Can an ESP8266 Go?
    https://hackaday.com/2018/01/22/how-low-can-an-esp8266-go/

    We’ve been tuned into coin cell designs lately given the coin cell challenge, so we were interested in [CNLohr]’s latest video about pushing the ESP8266 into the lowest-possible battery drain with coin cells. The result is a series of hacks, based on a reverse-engineered library and depends on a modified router, but that gets the power consumption down by more than a factor of ten!

    Although the ESP8266 has a deep sleep mode that draws only 20 microamps or so, that isn’t as rosy as it seems. If you could go to sleep for a while, wake up for just a moment, send your data, and then go back to sleep, that might be one thing. But when you use conventional techniques, the device wakes up and has to do about ten seconds of work (at high power) to connect to a nearby access point. Then it can do what you want and go back to sleep. That ten-second hit is a killer on small batteries.

    It used to be people were happy enough to just have to push a button in their car and have the garage door open. But pushing a button means you have to use your hands, like it’s a baby toy or something. We’re living in the 21st century, surely there must be a better way! Well, if you’ve got a home automation system setup and a spare ESP8266 laying around, [aderusha] may have your solution with MQTTCarPresence.

    The theory of operation here is very clever. The ESP8266 is powered via the in-dash USB port, which turns on and off with the engine. When the engine is started, the ESP8266 is powered up and immediately connects to the WiFi network and pushes an MQTT message to Home Assistant. When Home Assistant gets the notification that the ESP8266 has connected, it opens the garage door.

    An IoT remote stove monitoring and control system designed to provide peace of mind to those out of the house.

    The lights are off, the doors and windows are locked, and you leave the home for a while. Then you remember that you forgot to check the stove. This hack aims to solve this very problem by using SMS for stove monitoring and control so that homeowners can ensure their piece of mind wherever and whenever they want.

    Given that almost all of us have experienced this problem some times, simplicity and reliability is a big bonus. That’s why I opted to use temperature sensors for monitoring and servos for control; it’s easily accessible and dirt cheap to buy.

    Router Rebooter Eliminates Hassles
    https://hackaday.com/2018/01/31/router-rebooter-eliminates-hassles/

    Some low-end or older routers might get you a decent WiFi network in your house or apartment, but often these cheaply made devices are plagued with subtle software problems that cause the router itself to become unresponsive after a few days of operating. One solution is to just power cycle the router by hand whenever the Internet disappears, but a better solution is to build something that does that for you.

    [Charlie] had this problem as the de facto IT person in his family, and didn’t want to keep getting bothered for such a simple problem. His solution involves a relay, an ESP8266, and a Wemos D1 mini. The device connects to the Internet through the router and occasionally sends out pings to another address. If it can’t ping the address successfully after a certain time period, the device power cycles the router by activating the relay.

    Follow This Guide to Set up a Three-Factor Authentication Entry Lock.
    I’m not going to pretend to know what you have that requires such advanced security, so I’ll just assume it’s to keep your room full of collectible action figures protected. With such a valuable collection, you’re going to want to lock it up tight with three-factor authentication. If you’re not familiar, multi-factor authentication is a security method where you’re required to use more than just the usual password.

    If you follow this nice guide over on Switched On Network, those authentication methods are: an RFID pass, a 6-digit pin number, and a randomly generated code sent via text message. The RFID card system, which you’ve likely had in your own employer’s office building, is remarkably unsecure. But, that situation is improved a lot by also requiring that visitors input a personal pin number. Finally, the randomly-generated code sent in an SMS message means that the visitor will actually need to be present — along with their phone.

    You can have all of that security pretty affordably with just a few components: a wireless Raspberry Pi, a USB RFID reader, a touchscreen LCD, and an electronic door strike.

    Measuring AC Current and Sending Data via MQTT
    https://www.hackster.io/brijn/measuring-ac-current-and-sending-data-via-mqtt-062c79

    A few components are combined to measure AC current from three lines and send the data out via MQTT.

    The IoT board
    As an early Linux adopter, I really like the Onion Omega boards. They are inexpensive ($10), have build in storage (can be extended), WiFi and run a “full” linux stack. Onion sells several boards that can be added to provide additional functions (relays, ethernet, mini display etc), but most of my sensors are purchased from NCD.IO. I use the I2C interface on the Onion Omega to connect the sensor.

    The software
    Some small python code reads the sensor data and pushed it out via MQTT to the Losant IoT platform. Since the Internet is not always available, it will cache data locally and push out to Internet when it becomes available. For a local user interface, the data is also pushed to a local NODE-RED install.

    If Your A/V Equipment Is Out of Reach, an ESP8266 Can Provide the Perfect Solution
    https://blog.hackster.io/if-your-a-v-equipment-is-out-of-reach-an-esp8266-can-provide-the-perfect-solution-1fb20174995c

    Jfessard found themselves in a situation that many of us know well: their A/V setup was hard to reach, and therefore control.

    The better solution that Jfessard came up with was to use Alexa for voice control. To make that work, the ever-useful ESP8266 was the perfect intermediary between the Amazon Echo and the A/V equipment. The ESP8266 is wireless, so it works over your network and doesn’t require line-of-sight.

    Getting an ESP8266 working with Alexa requires the use of fauxmoESP, which provides a workaround by emulating a Belkin WeMo device. Many virtual devices can be emulated on a single ESP8266, but they are limited to simple on/off functionality. In Jfessard’s case, that was suitable, as the projector just needed to be powered on, and turning “on” a particular HDMI port could simply fire the IR signal to switch to that port.

    This tutorial shows how to design a remotely operated humanoid robot, controlled over a Wi-Fi network, using an Arduino Uno connected to an ESP8266 Wi-Fi module. It uses some servomotors form head amd arms movements, some DC motors for moving small distances, and a face made of LED matrices. The robot can be controlled from an ordinary internet browser, using a HTML designed interface. An Android smartphone is used to broadcast video and audio from the robot to operator’s control interface.

    https://www.hackster.io/my-arduino-home/arduino-home-automation-control-board-4bf329

    This control board integrates with Arduino to allow users to control all aspects of a smart home through a website or Alexa voice commands.

    There are three user input interfaces that can be used. They are the mechanical buttons, web site, and Alexa command.

    The Arduino Home Automation Control Board integrates an Arduino Mega and an Arduino Ethernet Shield (Rev. 3) with a Cat5e hardwired smart home network. Each board has the ability to connect to 14 lights, 3 temperature sensors, and 2 garage doors or automatic gates.
