Lennox-branded heat pump on the Samsung RAC board family (modelNum
TP1X_LNX-AC-RAC-01001_0000) already routes correctly via the existing
'-RAC-' token, but its dump has two resources no prior AC fixture
carried: /mds/absencepowersaving/vs/0 and
/option/motiondetectwind/stateful/vs/0. Bind both as read-only
sensors, matching the CURRENT_LIMIT/ANOMALY_LOAD precedent -- nothing
in the dump confirms write safety on live HVAC hardware.
