A devkit which brings the accurate utility-grade energy monitoring with ATM90E26 to the masses. I started building a development board to go beyond the Arduino ADC’s in monitoring energy usage while maintaining the low-voltage safety features of a contactless system. This devkit allows the flexibility to build a custom energy monitoring system using the ATM90E26 with libraries supporting major Arduino flavours, MBed, Particle and Raspberry Pi.

There will also be the option to go the whole hog and support me in building a dual ATM90E26 system for single phase grid + solar monitoring . This unit uses a standard M2 (width of 2 circuit-breakers) din-rail enclosure and an SMPS (switch-mode power supply) allowing operation directly off the mains and compatibility for 120V-250V systems with no changes in the hardware.
