Smart EVSE Sensorbox

The Smart EVSE Sensorbox has three inputs for CT's (current transformers), and a 4 pin socket that provides the power to the Sensorbox and connects to the Smart EVSE controller's A/B +12V and GND connection.

The current transformers are of the type SCT-013-000, and can be ordered with the Sensorbox.
The Sensorbox does not come with a current transformer by default.

In order to let the Smart EVSE controller dynamically adjust the charge current, you will need to set the controller mode to SMART.
The controller now expects to receive measurement data from the sensorbox every two seconds.
If it does not receive any data for 10 seconds it will time-out, stop charging, and display an error message on the LCD.

Placement of the sensorbox 
In order to measure the current of other appliances, the CT's should be clamped on the MAINS wires directly after they enter the house. Usually three CT's are used, one for each phase. Connect the CT's to the Sensorbox, and use a 4 wire cable to connect the Sensorbox to the Smart EVSE.

Calibration 
The current measurements can be monitored from the CLI (command line interface) of the Smart EVSE by just pressing Enter. The last received measurement will be displayed on your terminal window. The actual current per phase, will also be displayed on the LCD of the controller.
If neccesary the current measurements can be calibrated by using the CAL command in the CLI of the Smart EVSE.

The Sensorbox comes pre-programmed, and it does not require any user interaction.
If you want to change the software and reprogram it, you will need a Pickit 2/3 or ICD3, as it does not contain a bootloader.
