If you read the posts about my XPEnology webserver you mayby know that plans where to find out how much power my “cheap” webserver was consuming. I’ve got a good feeling about power consuption but as we Dutch say ” meten is weten “.
The only way to know for sure is to measure and log energy consumption, preferably under different server loads/conditions.
As core for my project I wil be using a china energy meter type DDS238-2 ZN/S as shown in the picture above. One could measure power consumption by only using this meter but i would like to use it’s modbus feature to do some more detailed logging and probably connect it to my domotics system. I know you can buy lots of ready to use wifi energy meters but for me this is a nice oppertunity to get some ESP32 practice.
