This page features information regarding the beta firmware for the LZW31 that was released on 07/17/2020. 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.
V1.47 - 07/17/2020
Fixed: Bug that when you select the parameter in local config mode and do not edit it. If you long press the config key to save it, it will set to 0.
Fixed: If you are OTA during dimming, that will cause the bulb to flash.
Fixed: when a device is not on a network, a factory reset by holding down the config button for 25 seconds does not reset the configuration.
Fixed: multiple switches blink green (like they were excluded)when more than one switch is not on a z-ware network and one of those switches is
Add parameter 51, to enable instant on (ie: disable the 700ms delay). Note, if you disable the delay, it will also disable scene control except for Button 1 (ie: tap up 1x or tap down 1x) and button 7 (config button). All other buttons (2-6) will be disabled.
Size: 1 Byte
0: No Delay
1: 700ms Delay
Added parameter 52. Use to put the switch into "smart bulb" mode. If it set to 1, the power will output maximum % when the dimmer is on. 0 = normal operation, 1 = smart bulb.
V1.45 - 06/22/2020
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.
V1.44 - 05/27/2020
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.
V1.43 - 04/11/2020
Fixed: Bug where parameter 5 could not be set below 10.
Fixed: Bug that Switch Multilevel Start Level Change cannot change level below minimum level parameter number.
Fixed: Bug that Switch Multilevel Start Level Change command can not set the association device brightness to 1%.
Fixed: Bug where the LED bar would work abnormally when the local switch and aux switch are used together.
Modify the default value of parameter 11 to 100.
V1.41 - 03/28/2020
Homeseer: Fixed not processing BasicReports when sent after turning switch on/off from the wall. Changed to SwitchMultiLevelReport.
Vera: Fixed association purging issue. Vera was not properly processing group #4 group name. Shortened the name to resolve this issue.
Fixed state sometimes not being restored properly when local protection is enabled.
Fixed dimmer turning off when level rises above 80% on certain circuits. Make sure parameter 21 & 22 are set correctly.
Fixed an issue where when the user sets parameter 5 in switch config mode it causes an exception.
Fixed additional bugs for setting configuration parameters in switch config mode for parameters 5,9,10,11.
Fixed an issue where holding the down key to adjust a device in association group 4 would sometimes turn it off.
Fixed a bug where the duration of parameter 17 is far from the expected value.
Changing minimum level to 10% to accommodate likely use of LED bulbs.
