Firmware v1.48 (Beta) | LZW31-SN | Dimmer - Red Series (Gen 2)

This page features information regarding the beta firmware for the LZW31-SN that was released on 09/01/2020. 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 (NOTE: You will be responsible for to/from shipping costs and we will not provide any temporary switches -- also, estimated time for completion is 2-3 weeks upon receipt).

Previous Releases

V1.47 - 07/17/2020 

Bug Fixes

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 

Enhancements

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.
Parameter 51
Size: 1 Byte
Default: 1
Range: 0-1
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

Enhancements

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

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. 

V1.43 - 04/11/2020

Bug Fixes

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.
Fixed: Bug that meter report is sent during dimming resulting in an inaccurate report.
Fixed: Bug that power meter value is 0 when light brightness is 0.

Enhancements

Modify the default value of parameter 11 to 100.
Change the calculation method of parameter 20. Change it from % to KWH. 0=0.01KWH, 10=0.1KWH, 100=1KWH; Modify the range value of parameter 20 to 0~127.
Restart the "Safe guard" time of meter report when the level has been changed. The "Safe guard" timer is to prevent network flooding when device power fluctuates. 

V1.41 - 03/28/2020

Bug Fixes

Fixed Energy & power reporting not being disabled when configuration options are set to 0.
Fixed Power reports flooding network when bulb power consumption fluctuates frequently. 
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.
Fixed an issue where the interval time of Central Scene notification is far from the expected value.
Fixed the issue of sending two Meter reports when the device is powered on.

Enhancements

Notifications no longer turning off when user adjusts the level or performs various other actions on the switch.
Changing minimum level to 10% to accommodate likely use of LED bulbs.
Change the range of parameter 19 to 0,30-32767 to prevent users from choosing a value that may flood the network.
