Can SAJ solar inverter integration be configured with hostname instead of IP?


Is it possile to configure the SAJ solar inverter integration with a hostname (e.g. AWorks.home) instead of with an IP address? In my network the IP address changes regularly …
I can retrieve the current IP address using nslookup, but I have no idea how I could change the configrued IP into the current IP. Can anybody suggest any ideas or help?
