Been running this circuit and server DHT22 aggregator since May 2022.
Basically this is a client (actually a server – ESP32 REST respond server), and a windows server (that calls the ESP32 server every interval, and aggregates the data into a sqlite3 small db).
Win Server as can be seen on the screen shot, displays compared data of temperature/humidity of the last four days – graph x-temperature y-time_of_day.

Technical details:

• Win Server is a Delphi VCL Win32 application using TChart for the charts plot.
  In addition I’ve coded that the app taskbar icon, will light in RED when no connection can be made to the defined address.
• ESP32 chip Server is an espressif-IDF SDK,. C code,. ESP32 is simply connected GPIO to the DHT22 sensor (as can be seen on the chip wired image).
  In addition I’ve connected a red led light, that is turned on, when no connection is done for defined interval to the ESP32 server.
  Calls to the ESP32 server are replied structured in very simple REST JSON record format.

Wrote a small app, that takes all my aggregated Temperature data and displays it on a scale of PI per day,. according to the temperature every period of time.
Total 148 days,. total 2.4m records (probed every 5sec – on a sqlite3 db).
It scales from the color red when the temperature was about 24.9c — to the green/black (which is kinda these days) when temperature is about 29c~30c.
