Question about Solar Manager Manager Flux SM-1118-01

I simply integrated the Solarmanager into the home network and then I was able to integrate all the devices via the network. Solarmanager provided a short description for all devices. After contacting support, I also found a description for the integration

The solar manager is connected to the home network. All devices require a fixed IP.
You need to know exactly how the devices are connected to the grid in order to use the Solar Manager. Depending on the device, there must be a Modbus (RS485) connection. Some IT knowledge is required. If a Modbus connection is necessary, you may need to know how the PV is connected.

Exactly - it is simply a server that requires an IP connection to the PV components, control switches etc. and communicates with the portal via the Internet. It is important that your own components are on the list of supported devices.

the solar manager is connected to your own network via a cable and with the web interface and the online instructions you can then connect and control all devices in the network. if it doesn't work, support will help you.

The electrician installed it for me.
Important: the Solar Manager only runs with an annual subscription of approx. 40.
