Hi,
ist ist possible to connect the SMA ECHarger (22 kW power) by using the SMA Solar oder SMA Devices Plus integration. I don´t user Modbus now.
Hi, I don’t own a SMA eCharger myself, but you can try the custom integration for the SMA EV Charger. Based on this issue here, the eCharger seems to integrate in Home Assistant, as the it uses a similar API as the EV Charger.
