Energy Meter Pre-Programmed ESP32 Dev Module with EmonESP & ESP32 to Split Single Phase Energy Meter adapter. EmonCMS will need to be set up according to the instructions here.
The adapter comes with a special header to allow the ESP32 to sit flat against the pcb. It also has additional holes for each pin on the ESP32, in case you want to add something else.
Also included is an ABS plastic case with pre-drilled holes for the energy meter connections, ESP32 USB, and meter LED lights (in the case lid).
