Thanks for helping us close the loop on energy usage.
A breadboard-compatible ATM90E26 module I made to save myself
hundreds of dollars, which earned me a mention on Hackaday. Now it
can help you get started with energy monitoring as well.

All the parts you will need to use the ATM90E26 on a breadboard to
build a self-powering energy monitor with Wi-Fi connectivity. A NodeMCU and a 100 A YHDC current clamp
will be included as part of the kit. Voltage sampling transformer is the only other part
the user has to supply.

An Energy Monitor Featherwing with some essentials to get you going.
The Adafruit Feather and a 100 A YHDC current clamp will be included
as part of the kit. Voltage sampling transformer is the only other part
the user has to supply.
Something your electrician will feel good about installing. A fully featured
DIN rail module with options to install two ATM90E26 monitoring boards for grid + solar.
Can be interfaced with Wemos (ESP8266) footprint boards to add Wi-Fi, BLE, LoRa, and
other forms of network connectivity.

Secondary module for the DIN Rail Energy Monitor above which will add another phase into
the monitoring setup. Essentially the same as the breadboard version but with isolated
SPI bus making it suitable for use with high-voltage inputs. This module can be used to
measure a second phase or single phase solar output after the inverter. You can also use
it to design your own isolated high-voltage monitoring system.
