Integrating Stiebel Eltron ISG with OpenHAB 2

Hi everyone, I’m new to OpenHAB and currently setting up my OpenHABian instance. I have a Stiebel Eltron ISG and came across the Stiebel Eltron LWZ Binding in the documentation. However, I’m having trouble getting it to work with OpenHAB 2. The binding doesn’t seem to be listed in the add-ons section, and I’m not sure how to install it manually. I found a GitHub pull request (#2101) that mentions the binding, but I’m not familiar with how to integrate it into my setup. If anyone has experience with this or can guide me through the process, I’d greatly appreciate it! I’m excited to get this working and contribute to the community if possible. Thanks in advance!
