Build me a Webserver on ESP32 with Pulse counter (PCNT) for Power meter.

Job ID: 32977324

Budget: €250 – €750 EUR

Hey I need electricity metering system. Installed power meters has pulse outputs. Ex9EMS 3P 4M and
Iskrameco Mt174 M3K0
ESP32 with webserver will be connected with power meters. I need someone to develop webserver and
counting code on ESP. Web server have to work over internet not only in local network. Each meter
values needs to be saved on ESP monthly daily hourly, 12-month max.
Some version of schematic is drawn that needs to be review, PCB not ready has to be drawn In given
enclosure size.

 Input values changeable x imp/Kwh adjustment for each mater
 Name for meter like tenant Rudolf
 ESP32…. 18 power meter inputs if possible

Some literature for possible solutions and ideas.
