Update:

Have noticed that getting the IoT OnOff app (on IOS, I don't have an Android phone) is very difficult for most people, who are not hardish core IT geeks, to connect to an MQTT server.

To set this, I set up another MQTT server without authentication, and could not get IoT OnOff to connect on both server after many tries.

This means that, although I build this app as a public service, it is so difficult for users to get it to work, I did not really accomplish my objective, because of the problems with IoT OnOff, which I have no control over since I am not the developer and I have not found any contact information for the developer except his name (on FB, LinkedIn, email on web site, etc).

To confirm that my MQTT servers are working, I set up Node-RED today, and it connects very easily with both my MQTT servers.

Wuhan Coronavirus Stats for China (from "official" source) using Node-RED:

I like the IoT OnOff app, but most people would consider me in the "uber-IT-guy" or "super-geek" category.

So in the future, unless the connection bugs are worked out in the IoT OnOff app for the iPhone, I will have to find another platform for a rapid-prototype public service app dashboard.

Node-RED might be a candidate (more on Node-Red later), but I will check out some other MQTT visualization dashboard for the web beforehand.

NAME
App::Info::Handler::Prompt - Prompting App::Info event handler SYNOPSIS
use App::Info::Category::FooApp; use App::Info::Handler::Print; my $prompter = App::Info::Handler::Print->new; my $app = App::Info::Category::FooApp->new( on_unknown => $prompter ); # Or... my $app = App::Info::Category::FooApp->new( on_confirm => 'prompt' ); DESCRIPTION
App::Info::Handler::Prompt objects handle App::Info events by printing their messages to "STDOUT" and then accepting a new value from "STDIN". The new value is validated by any callback supplied by the App::Info concrete subclass that triggered the event. If the value is valid, App::Info::Handler::Prompt assigns the new value to the event request. If it isn't it prints the error message associated with the event request, and then prompts for the data again. Although designed with unknown and confirm events in mind, App::Info::Handler::Prompt handles info and error events as well. It will simply print info event messages to "STDOUT" and print error event messages to "STDERR". For more interesting info and error event handling, see App::Info::Handler::Print and App::Info::Handler::Carp. Upon loading, App::Info::Handler::Print registers itself with App::Info::Handler, setting up a single string, "prompt", that can be passed to an App::Info concrete subclass constructor. This string is a shortcut that tells App::Info how to create an App::Info::Handler::Print object for handling events. INTERFACE
Constructor new my $prompter = App::Info::Handler::Prompt->new; Constructs a new App::Info::Handler::Prompt object and returns it. No special arguments are required. BUGS

App::Info documents the event handling interface. App::Info::Handler::Carp handles events by passing their messages Carp module functions. App::Info::Handler::Print handles events by printing their messages to a file handle. App::Info::Handler describes how to implement custom App::Info event handlers. COPYRIGHT AND LICENSE
