I have successfully implemented systeminfo into my setup and it is reporting on the OpenHAB server perfectly.
Would it be possible to include additional machines in the reporting ?..I have a Windows box and a FreeBSD box I would also like to report on.
If you are familiar with SNMP you could leverage that to poll the other systems to pull the same system info into OH.
Sounds good, should be able to leverage that.
If you are looking for some example SNMP past the documentation examples, I wrote up a guide using it for phone detection: Leveraging SNMP to detect your mobile device
