With a little bit of work, was able to build a nice "Wuhan Coronavirus Status" app using MQTT and the IoT-OnOff app. More on this technique here:

ESP32 (ESP-WROOM-32) as an MQTT Client Subscribed to Linux Server Load Average Messages

The result turned out nice, I think. I like the look and feel of this app considerably better than other apps I prototyped, and it is much more cost effective (free).

If anyone wants to build such an app like this, please just let me know (post back in this thread) and I will show you how to build this, step-by-step. If you want to you my MQTT server / service, I can make that happen for you as well.

So, in nutshell, you can have this "Wuhan Coronavirus" public service status app working for free, 100% and I assure you, 100% your usage data will be private and never shared with any third party, never under any circumstances. This is public app to help others, not to make money (as many companies seem to forget in times of crisis and look to profit from the misfortunes of others. Not here at unix.com! This app I created has one purpose - to help those who might need this information during a humanitarian crisis. This is how IT should really be used, to help others in times of need and crisis. If one person benefits, I am more than happy enough. I don't need money, fame or fortune from IT.

Wuhan Coronavirus Status for China - Rapid Prototype Blynk App with ESP8266

For the next part of this project, I think I will build a Node-RED dashboard app for macOS. I installed Node-RED yesterday when searching for dashboard app, but I need to import the dashboard widgets and set it up to display a dashboard with MQTT data,

Jifty::LetMe(3pm)					User Contributed Perl Documentation					 Jifty::LetMe(3pm)

NAME
Jifty::LetMe - A way to expose single-link URLs to your applications new Create a new "LetMe" authentication object; it takes no parameters. It calls "_init" to do any initialization. A LetMe is a way to provide a one-time-use URL for a particular purpose. All LetMe objects give you a way to validate a user's identity and to allow them a very small set of possible actions or page-access permissions. For example, you can put a LetMe URL in an email to a new user, so that when they click on the URL you know that their email address is valid. _init @_ Called with whatever "new" was called with. By default, does nothing. user Contains an app-specific "user" object. validated_current_user If the user has presented a valid token, returns an (app-specific subclass of the) Jifty::CurrentUser object for the user who has the email address in $self->email. If no user has that email address, returns undef. _user_from_email ADDRESS Returns an (app-specific subclass of the) Jifty::CurrentUser object for the user who has the email address ADDRESS. generate_checksum Returns an authentication checksum for the current combination of: user path arguments until generate_koremutake_checksum Generate a slightly more pronounceable version of the checksum using String::Koremutake. Due to hex -> integer limitations, this is imprecise and may vary depending on the platform it is used on; as such, it is deprecated. from_token PATH Parse a string of the form mylongusername@example.com/update_task/23/until/20050101/bekidrikufryvagygefuba into email => mylongusername@example.com, path => 'update_task/23' until => 20050101, checksum_provided => bekidrikufryvagygefuba as_token Returns the "letme" token for this set of credentials. This should round trip cleanly with from_token as_encoded_token A variant of as_token that encodes the user's email address suitably for passing in a URL as_url Returns the fully qualified URL for this LetMe. It's composed of Jifty->web->url, "base_path" and "as_encoded_token" base_path By default, all "LetMe" actions live at URLs under '/let' inside your application. Override this subroutine to change that. By default, it returns '/let/' validate Returns true if the credentials the user presented validate OK. Returns false otherwise. _correct_checksum_provided Returns true if the checksum the user provided is correct. Doesn't actually do much input checking. You want to call "validate" perl v5.14.2 2010-12-08 Jifty::LetMe(3pm)
