i just spent an hour searching the forums, asking google and roaming the / via ssh on my TS-932PX running qts 5.2.9 in oder to do a rather simple task:
read the smart data of my drives via ssh/cli (i know there is a sub-sub-window in the drives&snapshots section in the webui, but nothing i can export).
there is no smartctl an no obvious other tools (and the qts is not that well documented regarding cli tooling as it seems ..)
