Beta



V1.52 - 01/22/2021

Modified Smart Bulb Mode so that the output can only be turned off by sending a BasicSet(0x00).
Fixed: Solve the problem that the power measured by the light is 5W when the load is not connected (caused by inaccurate power measurement at extremely low power consumption).

V1.51 - 01/08/2021

Fixed: Low brightness would brighten and then darken when being dimmed.
Fixed: Issue where the same value of parameter 5 (Minimum Level) appears inconsistently when both parameters 21 (Power Type =1 - Neutral) and 22 (Switch Type = 1 – 3-Way) are set to 1.

V1.49 - 12/16/2020

Remove local configuration mode (to make space for extra features).
Adding parameter 50 to adjust the delay when parameter 51 is set to 1. 1=100ms, 2=200ms, 3=300ms, etc.
2x taps on the config button will now send a configuration report of a value 0 to indicate the animation has stopped.
Have device send “SwitchMultiLevelSet” every 1 second to associated devices as the device dims up & down for association group 3.
Config Button 2x press will turn off a notification and also send a 2x pressed scene to the hub.
Added scenes for pressed, held, released so that the black series can be used to control smart bulbs. 

V1.48 - 09/01/2020 

Bug Fixes

Fixed: S2 bootstrapping issue. Improves S2 compatibility with 700 series hubs like Hubitat C-7.

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).
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.   

V1.41 - 03/28/2020

Bug Fixes

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.  

Enhancements

Changing minimum level to 10% to accommodate likely use of LED bulbs.
