Scrapes web API from CR1000 and uploads data via HTTPPost query to script on webserver each new data entry.
PUSR USR-DR404 DIN-Rail RS485 To WiFi/Ethernet Converter
CR1000 connects via ethernet to converter that creates network. ESP32 connects to the USR-DR404 and scrapes data from API.
Web Server
PHP script extracts data values from Arduino query and inserts them into MySQL 8 database.
