-- Control path verified from live logs on a CALIBRATED motor:
--   open/close/stop -> standard window-covering cluster 0x0102 (cmd 0x00/0x01/0x02)
--   position        -> 0x0102 goToLiftPercentage (cmd 0x05); device returns
--                      Default Response status 0x00 and the position tracks the
--                      setpoint (commanded 30 -> feedback settled at ~33).
-- Note: EF00 dp2 does NOT act as a setpoint on this motor (it only mirrors the
-- current position), and goToLift is a no-op until the motor's travel limits are
-- calibrated -- which is why the earlier EF00-datapoint attempts all failed.
-- EF00 dp3 is the position feedback and the ONLY signal for remote/manual
-- operation (this firmware never reports a state datapoint). Following z2m
-- (tuya.valueConverter.coverPosition), every dp3 report also derives the cover
-- `state` (0=CLOSE / else=OPEN) via coverDeriveState, so state stays consistent
-- with position -- fixing the "shows previous state" lag and reflecting remote
-- ops. No gating/optimistic window: the report always carries a matching state.
