This Hack Lets You Use Alexa IoT Devices with Google Assistant
https://blog.hackster.io/this-hack-lets-you-use-alexa-iot-devices-with-google-assistant-e78ef62576f3
The Internet of Things (IoT) has a ton of potential, and the market has clearly shown that people absolutely want the convenience of home automation. The problem is a frustrating ecosystem of competing standards
Many IoT devices only work with one assistant, such as Amazon Alexa or Google Assistant. Blake W. Ford’s hack gets around that and lets you use Alexa devices with your Google Assistant.
Non-IFTTT Google Assistant Hacking
Google Assist anything by hacking the TP-Link HS105
https://hackaday.io/project/163011-non-ifttt-google-assistant-hacking
Google Assistant technology is largely based on a partner device model where 3rd party providers manage back-end connections to their unique smart devices. While eventually the process is as simple as saying “Ok, Google. Turn on -”, setup always includes a non-Google vendor login and a special step to allow Google as an Authorized user on that account.
I am working to rectify this. Specifically for devices where no partner agreement or account login exists but Google Home integration is desired.

Build A Home Automation Hub For $20
https://hackaday.com/2019/01/05/build-a-home-automation-hub-for-20/
With so many WiFi home automation devices on the market, you might want to take advantage of these low cost products without having to send your data to third-party servers. This can be accomplished by running your own home automation hub on your home network.
If you don’t want to use a full computer for this purpose, [Albert] has you covered. He recently wrote a guide on running Domoticz on the $20 GL-MT300Nv2 pocket router.
20$ Pocket router as Domoticz Home Automation Gateway
http://albert-david.blogspot.com/2019/01/20-pocket-router-as-domoticz-home.html
I built a openwrt based custom firmware(autom8box), that packs router_functionality+domoticz_server+mqtt_broker which is all-in-one home-automation-gateway-solution running on a cheap $20 router that can be purchased off-the-shelf.
Wifi based home automation products are cheaper compared to zigbee or z-wave products, but the downside is, wifi devices need internet connection to perform their function. Letting your home devices controlled by a bunch of cloud servers on the internet may not be the best idea.
Internet connectivity for home devices should be optional – user should be incharge of deciding whether he/she wants to expose the home-devices to internet(may be for remote monitoring/controlling purpose), but in today’s world, there are so called “alexa”/”google-home” compliant wifi devices who insist on internet else they wont work.
Thanks to the opensource community(tasmota/espurna/etc) for helping us to jailbreak those wifi devices like sonoff/blitzwolf/teckin/etc.. but jailbreaking solves part of the problem, still the need for a home-automation gateway is a challenge and requires some advanced knowledge of setting-up wifi_access_point + mqtt_broker + automation_gateway_server(ex: domoticz/openHab).
ff-the-shelf cheap wifi-router into a full-automation-gateway to support following functionalities.
wifi-access-point
dhcp and dns server
mqtt broker(mosquitto)
domoticz
GL-MT300Nv2 is a ~$20 device which supports opensource firmware like openwrt. All I did was to build my own variant of openwrt firmware that includes all necessary components like domoticz and mqtt-broker.
Downside of using this device as an automation-gateway is the limited-wifi-range and limited set of domoticz plugins(because of 16MB flash limit).

Get the position of your MKR GSM 1400 on your smartphone through an SMS with a Google Maps link.
we implemented a simple application that allows you to retry the latitude and longitude of the MKR GSM when an SMS with a security check letter is received. The sender number is recovered from the SMS received and a reply is created with the proper Google Maps link completed by the coordinates given by the location services provided by the u-blox module.

Win Back Some Privacy With A Cone Of Silence For Your Smart Speaker
https://hackaday.com/2019/01/17/win-back-some-privacy-with-a-cone-of-silence-for-your-smart-speaker/
To quote the greatest philosopher of the 20th century: “The future ain’t what it used to be.” Take personal assistants such as Amazon Echo and Google Home. When first predicted by sci-fi writers, the idea of instant access to the sum total of human knowledge with a few utterances seemed like a no-brainer; who wouldn’t want that? But now that such things are a reality, having something listening to you all the time and potentially reporting everything it hears back to some faceless corporate monolith is unnerving, to say the least.
There’s a fix for that, though, with this cone of silence for your smart speaker. Dubbed “Project Alias” by [BjørnKarmann], the device consists of a Raspberry Pi with a couple of microphones and speakers inside a 3D-printed case. The Pi is programmed to emit white noise from its speakers directly into the microphones of the Echo or Home over which it sits, masking out the sounds in the room while simultaneously listening for a hot-word. It then mutes the white noise, plays a clip of either “Hey Google” or “Alexa” to wake the device up, and then business proceeds as usual.

Front Door Camera Sends Automatic Alerts By Text
https://hackaday.com/2019/01/21/front-door-camera-sends-automatic-alerts-by-text/
For this project, [Peter] decided on a JeVois smart camera. More than just a USB webcam, it also packs a quad-core processor running machine vision algorithms. This allows object recognition and other tasks to be run on the camera itself. In this setup, [Peter] configured the JeVois camera to detect people. When a human is detected upon the doorstep, the camera sends a message to the connected Raspberry Pi over serial. The Raspberry Pi then captures a JPEG still from the camera over the USB connection, and, using Twilio, sends a notification to [Peter]’s phone.

In this episode, I finish the cheap IFTTT (Amazon Dash) Button with a spare ESP-01. It does not cost a lot, because it only needs a battery, a LED button, and three resistors. In its current version, it can call the IFTTT maker channel and start anything.
But it also can be used to switch many other things in your house if you adapt the sketch.

IoT – Send Push Notifications with ESP8266 WiFi – Low Power Door Switch Monitor 1uA!!

1 vuosi sitten
Two other good free options for push notifications on ESP8266
- Telegram Messenger (which is nice because you can also send messages to your device from anywhere)
- IFTTT (which is obviously very flexible, the notification could be an email, tweet or whatever else IFTTT supports)
I’ve written libraries for both and they are available on the Arduino library manager (with examples)
I do have a 2 minute video going through them on my channel “How to send push notifications with your ESP8266″, but if I link to it here the comment will get flagged as spam (and it’s already pretty spammy

Get Months of Battery Life from an ESP8266!
https://www.youtube.com/watch?v=1vs86fwEdtM
By using ESP.deepSleep(time to sleep or 0); rather than
ESP.deepSleep(time to sleep, WAKE_RF_DEFAULT); the power usage is even lower, like 0.02mA or 22uA!!! The Arduino sketch has been updated to reflect is change.
By putting an ESP8266 into deep sleep mode you can get months (if not years) of battery life on a single charge. In this video I go through how to do this and show you guys all a cool program to send push notifications to your phone at the same time!

Espressif gave us this possibility and, because it is so fast, they called it ESPnow. And it also works in the Arduino IDE.
In this video, we will
- Try to understand the difference between the standard ESP mode and ESPnow
- Build a working ESPnow connection for two ESP8266
- Check-out the transmission speed and
- Compare this speed with the speed if we connect the ESP to the internet
- Compare the Energy hunger of both modes
- And finally, compare the ESPs with another technology: LoRa

Solar-Powered OpenWRT Router For Mobile Privacy
https://hackaday.com/2019/01/24/solar-powered-openwrt-router-for-mobile-privacy/
Let’s not pretend we aren’t all guilty of it: at some point we’ve all connected to a public WiFi network to check our email or log into some site or service. We know the risks, we know better. But in a weak moment we can let the convenience of that public network get the better of us. What if you had a small secure router that you could use as an encrypted VPN endpoint, allowing you to connect to those enticing public networks while keeping your traffic secure? That’s precisely what [David] had in mind when he built this pint-sized solar-powered OpenWRT router.
