Using zwavejs (Not sure if legacy zwave system has same issue) the Start level change command appears to not work for both the system driver and the inovelli provided driver.

Seems like it maybe similar to: Lzw42 "Start Level Change" commande don't work - General Discussion - Inovelli Community
Any ideas?
