This page features information regarding the beta firmware for the LZW31-SN that was released on 05/27/2020. This firmware is intended for users that would like to test the fixes and features included in this release before it goes into production. It should be a fairly stable release that fixes several issues.
The attached .otz file is the Z-Wave Chip Upgrade that is target 0 in the Z-Wave PC Controller software.
The Holtek .bin file is the LED bar MCU firmware and is target 1 in the Z-Wave PC Controller software.
Updating the firmware is a fairly safe & fool proof procedure with Z-Wave. Please double check you are updating the correct device with the appropriate model number. Do not interrupt power to the device while the update is taking place.
Please proceed at your own risk. Bricked switches due to user error will not be replaced nor refunded. If you'd like to mail in your switch to have us do it for you, we're happy to do so.
Bug Fixes
Fixed: Bug when double press the switch immediately after using up/down button causes the LED bar to be incorrect.
Fixed: Holtek firmware was saving data too often causing the bulb to flicker.
