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,

NAME
APP - Show / manipulate APP TLV configuration SYNOPSIS
lldptool -t -i ethx -V APP [-c app] lldptool -T -i ethx -V APP [-d] app=prio,sel,pid DESCRIPTION
The APP TLV is an informational TLV and will advertise the current configured application table. If the peer APP TLV and a local APP TLV match the same selector and protocol field the local parameter is used. ARGUMENTS
app Configures a local application data field using the three parameters: priority (prio), selector (sel), and protocol (pid). The -d option can be provided to remove an entry which matches the three parameters. Theory of Operations The APP TLV is an informational TLV for most end stations. It is not expected that setting APP data should be required. Peer data will be processed and added to the application data table by default assuming there does not already exist a local entry with matching selector and priority fields. By adding APP data to the application table it is available for applications, eg iscsid, to query. Applications query for a specific proto- col and selector and may use this data to map traffic to the corresponding traffic class. EXAMPLE &; USAGE Configure ISCSI application for priority 4 on eth2 lldptool -T -i eth2 -V APP app=4,2,3260 Configure FCoE application for priority 3 on eth2 lldptool -T -i eth2 -V APP app=3,1,35078 Remove FCoE application for priority 3 on eth2 lldptool -T -i eth2 -V APP -d app=3,1,35078 Display locally configured application table on eth2 lldptool -t -i eth2 -V APP -c app Display last transmitted APP TLV on eth2 lldptool -t -i eth2 -V APP SOURCE
