When accounting for updated firmware, what are the differences between the LZW31 and LZW31-SN? My understanding is that, at the time of manufacturing, the key differences were related to the LED notification bar features, multi-tap scene control, and power monitoring. However, some digging on the forum indicates that this changed, at least to some degree, with subsequent firmware updates^. Given the current firmware changelogs show what appears to be a parallel track between the red and black dimmers for fixes and feature updates, the differences are further obscured. What differences remained at the time the LZWs were discontinued?
^ The threads “Black Series Scene Control with New Firmware” and “Black series config button (scene control)” indicate scene control was added to both the LZW30 and LZW31, but removed after version 1.5.2 due to space constraints (the first thread includes a firmware update screenshot depicting this, but the current LZW31 firmware changelog tells a different story).
