Using IR codes from Broadlink backup file

This is a continuation of yesterdays post about the Broadlink RM2 wifi remote.  I was able to test out using the codes to control my remote today.  They are stored in JSON format in the broadlink backup file.  The backup file is a zip file.  After you extract it there is a folder named SharedData.  There are several files in the folder.  The one that seems to have all the codes is named jsonIrCode.  The data looks like an array of objects, each with a code and some other information.









The codes are an array of numbers that can be converted to a byte array.  They are stored as signed integers and python seems to need unsigned so they need to be converted.  I wrote this code today to test them out.  This code isn't great, but it works to test the codes to see if they work.  I think I'm doing the byte conversion correctly.  Some of my codes seemed to work and others didn't.  I didn't get much time to work on it today though. The broadlink library came from here https://github.com/mjg59/python-broadlink

Edit:  I fixed a problem with this code converting the negative values in the arrays to positive values.  All the codes from my saved file work now,

Also here is some more information about how I got the backup file from the eControls app.  I used an app on my android phone named Packet Capture.  I started the capture and restored a backup in the eControls app.  Using what I got from that I was able to get the file using python.  Here is the code for that.  The values for the params and headers will need to be filled in with your own information.

Getting Hidden App Data From Your Google Drive

Some Android applications use space on your Google Drive to store data.  You can't see this data by browsing drive the normal way.  You can get access to it if you get the access token from the app and do a few other things.

I use an app to keep some notes and other things.  They require getting the paid version of the app to backup your data.  I wanted to see if I could get it myself without paying for the app.  I found out how to do this from this Stackoverflow post http://stackoverflow.com/questions/22832104/see-hidden-app-data-in-google-drive.  The example there uses php. Since I have been learning Python recently, I decided to see if I could do the same thing with Python.

 There is a pretty good explanation of why you need to go through all the steps you need to go through to get your data in the accepted answer for that post, so I won't go into too much detail about that here.


Setting Up an Angular 5 site on Github Pages

Getting Started

This article will go over all the steps to setup an Angular site on GitHub pages.  The site will use Angular's AOT compiling and be served from the docs folder of the repository.

To start with you can follow the guide here to setup a new Angular project. Then you will need to setup a repository on Github.com.  The name of the repository doesn't matter, this site will use the docs folder, not the specially named repository with USERNAME.github.io as the name.



Project Changes

After that open up the project in your editor and open the .angular.cli.json file.  Change the "outDir" to "docs".  This is where the files will be created when you build the project.  The contents of .angular.cli.json are shown below with all the changes discussed in the article.

Custom Domain

To use a custom domain for your site you need to create a file name CNAME that contains only the domain name.  The GitHub help page explains how to setup DNS and everything else you …
