RESA RTU requires a RS485 serial port to work. Please check if your Sofar EMS has an available RS485 port before setting up this integration. If not, you can use a RS485-Ethernet Converter or a RS485-USB Converter to connect the RESA RTU to the Sofar EMS.
As RESA RTU is using a RS485 serial connection, the used RS485 port on the Sofar EMS cannot be used for other devices and connections. Please check if your Sofar EMS has an available RS485 port before setting up this integration.
Login to the commissioning interface and make sure the devices are added to the Sofar EMS.
In the settings, the grid power limits should be set correctly. Click Settings and check the highlighted setting in the image. If necessary, adjust the settings.
