New for version 3.1:

• Built-in Buzzer/Speaker.
• Ext connector for future add-ons.

Features:

• Fits into a standard DIN rail enclosure.
• Measures the current consumption of other appliances, and automatically lowers or increases the charging current to the EV. (sensorbox required)
• The power sharing feature let's you connect up to 8 SmartEVSE's to one mains supply.
• Two switched 230VAC outputs, for contactors.
• Powered RS485 communication bus for sensorbox / Modbus kWh Meters.
• Can be used with fixed cable, or socket and charging cable.
• Automatically selects current capacity of the connected cable (13/16/32A)
• Locking actuator support, locks the charging cable in the socket.
• RFID reader support, restrict the use of the charging station to max 100 RFID cards.
• An optional modbus kWh meter will measure power and charged energy, and display this on the LCD.
• Built-in temperature sensor.
• RGB led output for status information while charging.
• All module parameters can be configured using the display and buttons.
• WiFi status page.
• Firmware upgradable through USB-C port or through the built in webserver.
• REST API for communication with external software (e.g. HomeAssistant)
• MQTT API
• Rudimentary support for home batteries
• Supporting delayed charging
• OCPP 1.6j compatible
• The controller operates at a mains voltage from 110-240VAC
• Dimensions (W x D x H):  52 x 91 x 58 mm (width: 3 DIN modules)
• Open Source Firmware. 

 This is only the controller, in order to build a EVSE you will also need:

• One or two contactors who switch the power to the EV.
  For three phase systems this can either be one 4 pole contactor (IKA432-40), or add a 2 pole (IKA232-20) contactor to switch phases 2 and 3, and allow for one phase charging on Solar.
  The contactors must be normal AC (230V) type. Energy efficient or silent AC/DC contactors will not work correctly.
  
  
• A Type 2 charging cable or charging socket, with 12V activated lock.
• Enclosure with DIN rail, for mounting the controller and contactor.
