I see folks on FB are starting to show interest in this app, so here are the steps to get started, for those who do not want login:

(1) Download and install the IoT-OnOff app. Basic use is free and that is all you need. Note, I am not the creator of this app and have no relationship with the creator at all.

Configure the app as follows.

(2) Go to settings:

(3) Then go to MQTT Broker and add the IP address of the MQTT server / service (and make sure all the other settings are the exact same as in the photo):

(3) Then go to the Authentication screen and add the user name and password to the broker service:
  • The user name is: <contact me, or reply back asking for user name>
  • The password is: <contact me, or reply back asking for password>

There is no "hidden meaning" to the user name and password, I just used them at random when I first installed and tested the MQTT message broker Smilie

Make sure you turn on "authentication" at the bottom of that screen:

(4) Next you configure your dashboard (just take a few minutes, see next post):

chromium-browser(1)						   USER COMMANDS					       chromium-browser(1)

NAME
chromium-browser - the web browser from Google SYNOPSIS
chromium-browser [OPTION] [PATH|URL] DESCRIPTION
See the Google Chrome help center for help on using the browser. <http://www.google.com/support/chrome/> This manpage only describes invocation, environment, and arguments. OPTIONS
Chromium has hundreds of undocumented command-line flags that are added and removed at the whim of the developers. Here, we document rela- tively stable flags. --user-data-dir=DIR Specifies the directory that user data (your "profile") is kept in. Defaults to ~/.config/chromium . Separate instances of Chromium must use separate user data directories; repeated invocations of chromium-browser will reuse an existing process for a given user data directory. --app=URL Runs URL in "app mode": with no browser toolbars. --incognito Open in incognito mode. --proxy-server=host:port Specify the HTTP/SOCKS4/SOCKS5 proxy server to use for requests. This overrides any environment variables or settings picked via the options dialog. An individual proxy server is specified using the format: [<proxy-scheme>://]<proxy-host>[:<proxy-port>] Where <proxy-scheme> is the protocol of the proxy server, and is one of: "http", "socks", "socks4", "socks5". If the <proxy-scheme> is omitted, it defaults to "http". Also note that "socks" is equivalent to "socks5". Examples: --proxy-server="foopy:99" Use the HTTP proxy "foopy:99" to load all URLs. --proxy-server="socks://foobar:1080" Use the SOCKS v5 proxy "foobar:1080" to load all URLs. --proxy-server="socks4://foobar:1080" Use the SOCKS v4 proxy "foobar:1080" to load all URLs. --proxy-server="socks5://foobar:66" Use the SOCKS v5 proxy "foobar:66" to load all URLs. It is also possible to specify a separate proxy server for different URL types, by prefixing the proxy server specifier with a URL specifier: Example: --proxy-server="https=proxy1:80;http=socks4://baz:1080" Load https://* URLs using the HTTP proxy "proxy1:80". And load http://* URLs using the SOCKS v4 proxy "baz:1080". --no-proxy-server Disables the proxy server. Overrides any environment variables or settings picked via the options dialog. --proxy-auto-detect Autodetect proxy configuration. Overrides any environment variables or settings picked via the options dialog. --proxy-pac-url=URL Specify proxy autoconfiguration URL. Overrides any environment variables or settings picked via the options dialog. --password-store=<basic|gnome|kwallet> Set the password store to use. The default is to automatically detect based on the desktop environment. basic selects the built in, unencrypted password store. gnome selects Gnome keyring. kwallet selects (KDE) KWallet. (Note that KWallet may not work reli- ably outside KDE.) --version Show version information. As a GTK+ app, Chromium also obeys GTK+ command-line flags, such as --display. See the GTK documentation for more: <http://library.gnome.org/devel/gtk/stable/gtk-running.html> <http://library.gnome.org/devel/gtk/stable/gtk-x11.html> ENVIRONMENT
Chromium obeys the following environment variables: all_proxy Shorthand for specifying all of http_proxy, https_proxy, ftp_proxy http_proxy, https_proxy, ftp_proxy The proxy servers used for HTTP, HTTPS, and FTP. Note: because Gnome/KDE proxy settings may propagate into these variables in some terminals, this variable is ignored (in preference for actual system proxy settings) when running under Gnome or KDE. Use the com- mand-line flags to set these when you want to force their values. auto_proxy Specify proxy autoconfiguration. Defined and empty autodetects; otherwise, it should be an autoconfig URL. But see above note about Gnome/KDE. SOCKS_SERVER SOCKS proxy server (defaults to SOCKS v4, also set SOCKS_VERSION=5 to use SOCKS v5). no_proxy Comma separated list of hosts or patterns to bypass proxying. FILES
~/.config/chromium Default directory for configuration data. ~/.cache/chromium Default directory for cache data. (Why? See <http://standards.freedesktop.org/basedir-spec/latest/> .) BUGS
