Forbes on Forester : {molt interessant}

“IBM and Oracle will retreat to familiar territory, and Alibaba will threaten Google …
In 2020, IBM and Oracle will no longer try to win on the general-purpose, hyperscale, global public cloud platform battleground now dominated by AWS, Azure, Google and Alibaba.
IBM will focus on helping enterprises use the OpenShift development platform, on any cloud, to modernize core business apps.
Oracle will focus on its SaaS and autonomous database products, recommending Azure for general-purpose cloud development services like AI/ML, Kubernetes/containers, internet of things (IoT), and other emerging innovations.”

Market share May 2021 :

• AWS 32 %
• Azure 19 %
• Google 7 %

“AWS had the unusual advantage of a seven-year head start before facing like-minded competition. As a result, the AWS services are by far the most evolved and most functionality-rich.”

As a result of these trends, cloud data warehouse customers should look for providers that offer:

• A solution that simplifies a data warehouse deployment.
  Finding new insights from data is an iterative, continuous, laborious process that requires a stable data warehouse.
  Look for solutions with expanded automation capabilities to automate data ingestion, query tuning, data processing, and data integration to accelerate various business use cases.
• A solution that can deliver the performance and scale requirements you need.
  As you start to store and process large amounts of data, performance and scale become critical.
  Look for solutions that support thousands of concurrent users and queries per second and offer the ability to scale up and down based on business requirements.
  Ask the vendor for customer references when storing and processing more than 100 terabytes of data or dealing with more than 100 concurrent users.
• A roadmap that is as bold as your cloud ambitions.
  Most providers continue to simplify their solutions by enabling nontechnical users to access data directly.
  Look at vendors' roadmaps that focus on integration with data lakes and object stores, enable AI and ML automation capabilities, expand integration with various cloud software-as-a-service (SaaS) sources, and support enhanced analytics capabilities natively.

• Google gains strong momentum across various industry verticals.
  Google BigQuery is a fully managed, serverless cloud data warehouse that utilizes columnar storage and can scale to hundreds of petabytes leveraging standard SQL.
  BigQuery integrates with Cloud BigTable, Google Cloud Storage, Cloud AI Notebooks, and Google Sheets, giving users the ability to join data across various systems.
  Data engineers can access BigQuery's storage layer with Spark, Dataflow, and other processing tools, further uniting Google's data ecosystem.
  BigQuery has built-in machine learning capabilities, which allows the creation and execution of ML models using SQL queries.
  You can access BigQuery using Cloud Console, the command-line tool, or REST APIs using various client libraries such as Java, .Net, or Python.

  Customers like Google's frequency of new data warehouse releases, business value, future-proof architecture, high-end scale, geospatial capabilities, strong AI/ML capabilities, good security capabilities, and broad analytical use cases.

  Top use cases include business intelligence (BI) acceleration, internet-of-things (IoT) analytics, customer intelligence, AI/ML-based analytics, data science, data collaboration, and data services.

• Amazon Web Services' Amazon Redshift continues to have strong adoption.
  Amazon Redshift is a mature cloud data warehouse with broad capabilities and an expanding ecosystem.
  It is a fully managed, petabyte-scaled data warehouse that's part of AWS Analytics Services, including Amazon Kinesis, Amazon Elasticsearch Service, Amazon CloudSearch, Amazon EMR, Amazon Athena, Amazon SageMaker, and AWS Glue.
  Amazon Redshift can save results back to an S3 data lake that can be leveraged by other analytical services such as Amazon EMR, Amazon Athena, and Amazon SageMaker.

  Top use cases include BI, data services, AI/ML-based analytics, data science, and customer intelligence.

Open Local API (The "Gold Standard")

• Shelly
  Every Shelly device has a built-in web server and a fully documented HTTP/MQTT API. You can control them via a simple web browser command like http://[device-ip]/relay/0?turn=on
• Meross: via the Meross LAN integration (e.g. in Home Assistant) you can control Meross plugs locally using HTTP or MQTT.
• Athom / Kauf / CloudFree
  pre-flashed with Tasmota or ESPHome (open-source firmware). They are "born" open.
• Espressif-based / ESP8266 Plugs: some smart plugs built on ESP chips support local control
• ROWI Smart Plug has an open REST API and works locally, especially with ESPHome integration
• myStrom offers documented local REST API capabilities.

The "New" Open (Matter over Wi-Fi)

• TP-Link Kasa / Tapo - look for models like KP125M or P125M.
  If you buy the non-Matter versions of these same plugs, the local API is often restricted or proprietary.
  If you buy the Matter version, it is locally open to any Matter controller (Apple Home, Home Assistant, Google Home).
• Meross - kook for models like MSS115.

Closed :

• Tapo after firmware version 1.4
• Wyze - aggressively cloud-dependent.
• Amazon Smart Plug - locked exclusively to the Alexa ecosystem.
  There is no way to send a command to this plug without going through Amazon's servers.
• Tuya / Smart Life (Standard Wi-Fi Models)
  Millions of generic "Smart Life" plugs use Tuya chips. Out of the box, they are cloud-only.

Gemini "what smart plug have open local api and what ones have it closed"

It is a standardized way for smart devices to talk to each other over your existing Wi-Fi network.

The device you buy has to have the "manual pairing code" from the device printed on the plug ! Sample : "3497-211-2365"

There are Python implementations and libraries that support the Matter protocol

• CircuitMatter is a pure Python implementation of the Matter IoT protocol. It allows you to create and control Matter devices directly with Python,
  github -> ? AdaFruit ?

• there are also Python bindings and SDK components from the official Matter (Connected Home over IP) project, allowing you to write Python scripts that simulate Matter devices and respond to commands. E
  Example scripts exist to handle on/off commands using Python callbacks.

• the python-matter-server project implements a Matter controller server in Python, communicating over WebSockets.

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform

AWS Services for Mobile App Data Management - AWS provides multiple ways to store and manage your data so you can choose the right services to fit your needs for your mobile application.

• cloud storage - Amazon S3
• user data sync and identity management - Amazon Cognito
• NoSQL database - Amazon DynamoDB

Amazon Simple Storage Service (Amazon S3) is an object storage service that offers scalability, data availability, security, and performance.
This section demonstrates how to use the AWS SDK for Python to access Amazon S3 services : examples

Boto is the Amazon Web Services (AWS) SDK for Python. documentation

Alexa Voice Service (AVS) Integration is a new feature of AWS IoT Core that enables device makers to make any connected device an Alexa Built-in device.

AVS iOT, docs aws amazon index

Smart home skills provide a simple way for you to enable Alexa voice interaction to control and check the status of cloud-connected devices.

• Smart Home skill API
• Alexa skills kit

The code for your smart home skill is hosted as a Lambda function on AWS. AWS Lambda is a service that lets you run code in the cloud without managing servers. Alexa sends your skill requests and your code inspects the request, takes any necessary actions such as communicating with the device cloud for that customer, and then sends back a response.

1. to configure a new smart home skill, you need an account on the Amazon Developer Console. If you don't already have an account, go to https://developer.amazon.com/alexa/console/ask and create an account.
   done (20200520) - dashboard

2. open the Amazon Developer Console in a browser

3. click the "Create Skill" button and enter the skill name

4. under "choose a model", select "Smart Home" and click "create skill"

5. select "Payload Version" as "v3" and click "save"

6. copy "your skill id" to clipboard - amzn1.ask.skill.db6b2313-dfdf-4e51-a7b9-ba0fcad361ee

7. "default endpoint" required - provide the Amazon Resource Name (ARN) for your Lambda function -> {later}

8. sign in to your AWS Account

9. create an IAM Role for Lambda - if you haven't worked with Lambda before, you will need to create an Identity and Access Management (IAM) role that enables basic execution.
   1. to create an IAM role, Navigate to the IAM console
   2. choose Roles and click ""Create a new role"
   3. select AWS Lambda under AWS Service Role
   4. name = "sebas_lambda_role"

10. create a Lambda function and add code :
    1. on the AWS Console , region N. Virginia (top left), under Compute, select Lambda
    2. select region , then
    3. click "create a Lambda function"
    4. select "Author from scratch" and fill
       • name = "first_lambda" -> "lambda_1"
       • runtime "nodejs 12.x"
       • role = sebas_lambda_role

    "Successfully created the function first_lambda" / "Successfully created the function lambda_1"

11. we are placed in "Configuration" of "first_lambda"

12. in the Configuration designer, under "Add triggers" select the "Alexa Smart Home trigger"

    No el trobo (first_lambda) -> depen de la "region"

    El trobo amb North Virginia !

13. in "Application ID", write de Application ID from the Developer Console, as "amzn1.ask.skill.db6b2313-dfdf-4e51-a7b9-ba0fcad361ee"

14. leave "Enable trigger" checked

15. click "Add" -> "The trigger db6b2313-dfdf-4e51-a7b9-ba0fcad361ee was successfully added to function lambda_1. The function is now receiving events from the trigger"

steps {*** brutal ***}, manage skills in the developer console,

We have "n" consoles

• Amazon Developer Console - create a skill and get skill_ID
  see "skill configuration"

• IAM console - Identity and Access Management
  we have a role that enables basic execution

• billing console

To access AWS from python we go :

1. install boto : "sudo pip install -U boto"
2. access AWS console and get Access Keys and store then into /etc/boto.cfg

There are basically 3 components involved here:

• a web service from TP-Link

• the Kasa app that runs on your Smartphone, connected to Internet. It does (at least) two things:

  • periodically get the status of the plug (is it turned on/off), and show the status in the app (green icon if the plug is switched on). This happens every two seconds, when the app is in foreground and visible.

  • when the user toggles the switch from the app, it will send the new relay state change request to the TP-Link web service.

• the plug, connected to Internet via your wifi network. It will periodically contact the TP-Link web service for any status change, like a request to turn on/off.

tplink cloud api, how to control HS100 from internet

Kasa Smart is an Android app that lets you add, configure, monitor, and control your connected TP-LINK Smart Home devices from anywhere in the world.

Device Setup - the Smart Plug has two physical buttons: an on/off relay switch and a device reset button that resets the device if pushed for five seconds or longer.

When plugged in, an unconfigured or freshly reset Smart Plug will start an unsecured open access point with the SSID “TP-LINK_Smart Plug_XXXX” where XXXX are four hexadecimal numbers.

TP-Link’s Smart Home app “Kasa” makes the smartphone connect to this access point, sends UDP broadcast packets to 255.255.255.255 to find the Smart Plug IP and proceeds to configure it with the SSID and password that the user entered into the app. The Smart Plug then turns off the Access Point and connects to the configured WiFi as a client. - Lubomir Stroetmann reverse engineering

Compte : Storming the Kasa? Security analysis of TP-Link Kasa smart home devices devices by Andrew Halterman

Port 9999 TCP is used for controlling the Smart Plug on the local network via the Kasa app and is described in the TP-Link Smart Home Protocol section
Port 1040 UDP is described in the TP-Link Device Debug Protocol section

There are 3 steps in managing a TP-Link Smart Plug using CURL, from here :

1. authenticate and get a token - url

2. get device list and URL - url

3. manage the device - url

Run it at MARS/sebas/tpcloud/tpc.sh

There are a lot of companies offering low cost devices, e.g. Sonoff, Tuya, Jinvoo, Teckin etc.

Most of these solutions are based on ESP32 or ESP8266 , both system on a chip microcontrollers
See How to set up ESP8266 as a WiFi Access Point (AP Mode)

ITEAD’s Sonoff line is a range of Internet-of-Things devices based around the ESP8266 - hackaday

Which app is better Smart Life or Tuya ?
Tuya Smart App and Smart Life App are both official Tuya App.
The only difference between the two is that the Tuya Smart App uses the Tuya logo and elements, while the Smart Life App removes all Tuya logo and elements.

To pair the device to the local network, we have 3 options :

• EZ mode pairing (fast blinking, 2 times per second)
• AP (access point) pairing (slow blinking, 1 time every 2 seconds)
• Bluetooth (dual-mode product)

1. power on the device first.
2. then, enable Bluetooth on your mobile phone
3. open the app.
4. Bluetooth and Wi-Fi+Bluetooth dual-mode devices that are ready for pairing will be displayed.

1. You set the IoT device into a promiscuous listening mode
2. From a mobile device connected to a WiFi Access Point, you start SmartConfig pairing using the relevant app
3. Your mobile device encodes your WiFi credentials into sequences of data length values
4. Your mobile device sends the sequences of broadcast UDP packets to your WiFi AP
5. The IoT device sniffs the sequences and decodes the data lengths to retrieve the WiFi credentials
6. The IoT device joins the WiFi network using the credentials and continues communication from there

The mobile App sends a UDP broadcast packet or a multicast packet containing the SSID/Password into the air.
The Wi-Fi module of the device will receive the UDP packet as long as the UDP organization form is recognizable.
SSID/Password will be decrypted in the received UDP packet and sent to join the Wi-Fi router.

In this mode, the IoT device creates its own Wi-Fi network (hotspot, named "SmartLife-XXXX").

AP (Access Point) pairing works as you expect, similar to Google Chromecast and similar devices.
The device will start it’s own AP, you connect to it and share your WiFi credentials,
Then the device closes the AP and joins into your local network.

• with a plug, with only one blue button :
  1. plug the plug
  2. push the blue button for 5 seconds
  3. LED will start fast blinking (EZ mode)
  4. push the blue button again for 5 seconds
  5. LED will start slow blinking (AP mode)

• with a bulb, with no buttons at all :
  1. plug the bulb
  2. on the swith, go ON-OFF-ON-OFF-ON-OFF in a slow pace (1 change per second)
  3. bulb will start fast blinking (EZ mode)
  4. again, go ON-OFF-ON-OFF-ON-OFF in a slow pace (1 change per second)
  5. bulb will start slow blinking (AP mode)

• elt tam - technical details :
  smartconfig example

• Tuya Smrt APP user manual

Tuya devices can be controlled via both MQTT and HTTPS API - see tuyapi

Tuya devices use port 6668 ( lemariva ), while TP-Link devices use port 9999 ( softscheck )

when a device sends a broadcast to port 6666/6667 (UDP), that’s when we connect

Based on python-tuya, python 3.6.1 interface to ESP8266MOD WiFi smart devices from Shenzhen Xenon and tuyapi - a library for communicating with devices that use the Tuya cloud network

See how to get device id and local key

I have a Teckin SmartPlug SP21 at IP = 192.168.1.87 {some time ago}

So we try :

Looks like we have a "Tuya-like" device at home.

Lets try kasa :

Lets discover the "TP-Link" devices around MARS :

There is nothing, as tp-kasa is a Python library to control TPLink smart home devices, and my device is Teckin, not TPLink

First we read lemariva :

This only works with devices known as "Tuya-like", as Teckin outlets. If your power outlets are compatible, they should have the port 6668 opened

description , github

To access a Tuya device from python we need :

• (a) device IP
• (b) device ID
• (c) "version"
• (d) LOCAL_KEY

We get "device IP" from DHCP or by Wireshark.

Then, we need "device ID" : inside the "Smart Life" app, select the plug you wish to monitor, select the edit pencil icon in the top right and then "Device Information".

Or you can use tuya-cli :

Without "Smart Life", we can access tuya-like devices using python libraries : pytuya or tinytuya {***} or tuyapi

Here is configuring and programming instructions - tinytuya at github

And here is Jason A. Cox's code

read descr - Note: Devices need to be activated by Smart Life App

Starting with v1.3.0, TinyTuya can also connect to the Tuya Cloud to poll status and issue commands to Tuya devices.

This is a compatible replacement for the pytuya PyPi module.

Magnificent command :

If we get this error message :

... it is probable you have to use :

On the opposite situation, you can get this message :

... and you have to use version 3.3 instead of 3.4

The Tuya devices send back data points (DPS) also called device function points, in a json string.

The DPS attributes define the state of the device.

Each key in the DPS dictionary refers to key value pair, the key is the DP ID and its value is the dpValue.

You can refer to the Tuya developer platform for definition of function points for the products.

How to get a DPS dump :

From here :

Posem al darrer nivell :

First we verify

Devices running the latest protocol version 3.3 (e.g. Firmware 1.0.5 or above) will require a device LOCAL_KEY to read the status. Both 3.1 and 3.3 devices will require a device LOCAL_KEY to control the device.

Follow these instructions to get the LOCAL_KEY:

1. create a Tuya Developer account on iot.tuya.com and log in.

2. go to Cloud Development -> Create a project (note the Authorization Key: API ID and Secret for below)
   Authorization KeyAccess ID/Client ID: kska5drqa54nec0vpte3 API ID Key Access Secret/Client Secret: f73dd40109aa440292ee22d3540a02ad API Secret

3. go to Cloud Development -> select your project -> Project Overview -> Linked Device -> Link devices by App Account (tab)

4. click 'Add App Account' and it will display a QR code.
   Scan the QR code with the Smart Life app on your Phone by going to the "Me" tab in the Smart Life app and clicking on the QR code button [-] in the upper right hand corner of the app.
   When you scan the QR code, it will link all of the devices registered in your Smart Life app into your Tuya IoT project.

5. verify under Cloud Development -> select your project -> API Setting / API Group that the following API groups have status "Open":
   • Authorization management
   • User management
   • Device Management
   • Network Management
   • and Device Control

For retrieving the firmware bin, if you have physical access to the ESP microcontroller inside the device, you can connect over serial and use esptool.py to backup the firmware directly.
There's plenty of guides to do this, such as on the Espurna and Sonoff-Tasmota wikis.

Projecte : tuya-convert, amb instruccions per Tasmota i Tasmota i ESPurna i Docker

Some manufacturers have been silently switching from the ESP82xx based modules to other chipsets, and the flashing can not be done. So, tuya-convert does not workk on new devices.

Superhouse steps :

1. install tuya-convert on raspberry + "install_prereq.sh"
2. connect raspberry cable to internet
3. connect smartphone to "vtrust-flash" wifi (pwd "flashmeifyoucan")
4. run "start-flash.sh"
5. set device into flashing mode ("EZmode", push power button for 5 sec) - LED blink fast
6. connect device to same wifi
7. install Tasmota
8. update device to have all functions

See code at github : ESP32 + AWS + App !!!

The people at OpenEnergyMonitor have an open source system called EmonCMS.
It’s specifically designed to ingest data from energy monitors.
It either runs on a Raspberry Pi that you host yourself or you can use their cloud service.

Every 30 seconds it sends 30 readings over an MQTT connection to the AWS IoT service.
Once the message is received, an IoT Rule is triggered that writes the raw reading to a DynamoDB table.
This happens 2880 times a day (2 times per minute, 1440 minutes in a day).

Instead, I realized that older data doesn’t have to stay stored in DynamoDB. I could offload old data and store it on S3 instead!
So, I made a Lambda function that is triggered at night and archives all readings from the past day to a single CSV file on S3

What is AWS IoT?

AWS IoT provides the cloud services that connect your IoT devices to other devices and AWS cloud services. AWS IoT provides device software that can help you integrate your IoT devices into AWS IoT-based solutions.

If your devices can connect to AWS IoT, AWS IoT can connect them to the cloud services that AWS provides.

First, you will need an AWS account. It’s free and easy to create an account. Sign up now.

After you configure the AWS IoT Button to connect to your Wi-Fi network and provision the button with an AWS IoT Core certificate and private key, the button will securely connect to AWS IoT Core and publish a message on a topic when clicked.

You can use the AWS IoT rules engine to set up a rule and configure single-click, double-click, or long-press events to be routed to any AWS service.

You can configure it to send you a notification through Amazon SNS or store the clicks in an Amazon DynamoDB table.

You can even code custom logic written in Node.js, Python, or Java in an AWS Lambda function, and then configure the function to connect to third-party services or other AWS IoT-powered connected things.

3 flavors : for iOS, for Android, for Web.

Setup & prerequisites :

• a device running Android 2.3 and Google Play services 9.0.0

• an Android Studio project and its package name

• Android Studio 1.5
  Linux android-studio-ide-143.2821654-linux.zip 284 MB

• the Google Play services SDK from the Android SDK Manager

To install Android Studio on Windows, proceed as follows:

1. Launch the .exe file you downloaded.

   We could not detect a Java Development Kit (JDK) v7 or newer on your system.

   Get jdk-7u79-windows-x64.exe or jdk-8u92-windows-x64.exe better. Install it :

   C:\> java -version java version "1.8.0_92" Java(TM) SE Runtime Environment (build 1.8.0_92-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

   Read doc

2. Follow the setup wizard to install Android Studio and any necessary SDK tools.
3. On some Windows systems, the launcher script does not find where the JDK is installed. If you encounter this problem, you need to set an environment variable indicating the correct location : C:\Program Files\Java\jdk1.8.0_92

   Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.8.0_77.

  Google Cloud IoT Core uses Cloud Pub/Sub underneath that can aggregate dispersed device data into a single global system that integrates seamlessly with Google Cloud data analytics services.

• what are "DPS keys" ?

  The Tuya devices send back data points (DPS) also called device function points, in a JSON string. The DPS attributes define the state of the device. Each key in the DPS dictionary refers to key value pair, the key is the dpID and its value is the dpValue. You can refer to the Tuya developer platform for definition of function points for the products.
