Firmware v1.45 (Beta) | LZW31 | Dimmer - Black Series (Gen 2)

This page features information regarding the beta firmware for the LZW31 that was released on 06/22/2020. 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.


Removed parameter 7 (Invert Switch) and parameter 10 (Default Level) in local configuration mode. This was to make room on the limited Z-wave 500 chip for the following changes:
Increase the output ratio value on the PWM for better compatibility of Smart Bulbs when in single pole or aux switch mode.
Added the ability to change the LED bar to white when parameter 13 is set to 255.

Currently Hubitat does not support the upgrade of the Holtek .bin file. There may be some bug fixes or enhancements that may not be preset without updating both targets.
