What an excellent idea. I was just wondering if this would be possible only to find a complete guide available to me. Thanks a lot for posting your setup.
At the moment I have a POPP ZB Stick connected directly to my home assistant server, but having it located elsewhere will be much better in terms of signal strength. So I will definitely give this a try.
I’m already using an old Raspberry Pi with ser2net to connect to my smart utility meter which is nowhere near my home assistant server. Adding a couple of new lines to my ser2net config is something I think I can probably handle.
