SmartEVSE-2 Home Assistant Integration

Overview

The SmartEVSE-2 integration for Home Assistant allows you to monitor and control your SmartEVSE electric vehicle charging station. This integration provides real-time data about charging status, power consumption, and allows you to control the charging process.

Features

• Monitor charging status
• View real-time charging current
• Control access to the charging station
• View error states and diagnostics
• Integration with Home Assistant energy management

Requirements

• Home Assistant
• SmartEVSE charging station with firmware version 2.30
• RS485 to Ethernet converter (see note below)

Note on Connectivity: The author of this integration used a Waveshare RS485 to ETH converter to connect the SmartEVSE (which uses RS485) to the local network via Ethernet. This allows for Modbus TCP communication.
