Firmware Version	Date Released	Enhancements Added	Bug Fixes	Notes
1.07	Feb. 26, 2024	Parameter Related Changes Changed P120(single tap handle): Modify the behavior of single tap handle. In onoff mode, only the operation with single tap handle 0 is supported. Changed P12: Fix auto off timer that was broken in 1.05.	Fixed the bug where the firmware was missing mfg and model info. Removed Keep-alive on hubs that do not support it.
1.06	Feb. 6, 2024	Parameter Related Changes Changed P120 (Single Tap Behavior) default value to 1 Changed P120 (Single Tap Behavior) When P120 = 2, each up press cycles up through the speeds, if it’s on high, it cycles back to low; and obviously a down press turns it off. If it’s off an up press returns to last state. As per @tasinclair4 Blue Series Fan Switch Firmware Changelog \| VZM35-SN - Switches / Firmware Discussion - Inovelli Community	Changed the behavior of keep alive cluster to stop using keep alive cluster when hub does not support it (Related to Hubitat bug). Fixed the case where non-nuetral could not be identified. This would result in the switch boot-looping when turned on.
1.05	Jan. 18, 2024	Parameter Related Changes Modified the following parameters: 55, 56, 120, 121, 129, 130, 131, 132, 133, 134 P55 - Range is now 2-254 P56 - Range is now 0-254 P120 - Changed how a single tap on the switch works 0 = Old Method 1 = Single tap cycles through speeds P121 - Added Fan Timer Mode (see button related changes for more info) 0 = Off 1 = On P129 - Added Breeze Mode 0 = Disabled 1 = 0xffffffff (see Breeze Mode Calculator) P130 - Added config button binding mode 0 = Disabled 1 = Multi-Tap (1 = Low, 2 = Medium, 3 = High, Hold = Off) 2 = Cycle Mode P131 - Low speed for config button binding mode P132 - Medium speed for config button binding mode P133 - High speed for config button binding mode P134 - LED Color for config button binding mode Binding Related Changes When in the local protection state, you can also restore the factory settings by the usual method Combo Button - To Change the Fan switch single tap mode Single Tap Old Method = Hold Up + Tap Config 12x = LED Pink Single Tap New Method = Hold Down+ Tap Config 12x = LED Cyan Combo Button - To Enable Initiator Mode (used to bind this device to the new fan + light module) Hold “up” + press “config” 2x: EP2 enters Initiator Mode, LED pulsing in purple. If binding is successful, LED flashes green 3 times; if unsuccessful, LED flashes red 3 times. Hold “up” + press “config” 3x: EP3 enters Initiator Mode, LED pulsing in cyan. If binding is successful, LED flashes green 3 times; if unsuccessful, LED flashes red 3 times When P129 (Breeze Mode)!= 0, Tap down 4x = enable breeze mode If Fan Timer Display Enable (P121 = 1) Tap Up 1x = Fan Turns On Tap Up 2x = 5 minute timer Tap Up 3x = 10 minute timer Tap Up 4x = 15 minute timer Tap Up 5x = 30 minute timer Tap Down 1x = Fan Turns Off (timer is cancelled if it is still on) Device Function Changes EP1 add new cluster 0x0202(Fan Control Cluster Server) (This should present an additional device in ZHA that shows as a fan). We can change the speed of the current fan switch by writing the attribute “fan mode” of the fan control cluster. fan mode supports off, low(level = 25%), medium(level = 50%), high(level = 100%), auto When P129 is not 0, setting auto will enter breeze mode. Add a new Endpoint Dimmer Switch(Exactly the same as EP2) Endpoint id: 3 Device id : 0x0104 Cluster list: Basic(id : 0x0000 ,Server) Identify(id : 0x0003 ,Server&Client) Groups(id : 0x0004 ,Server) Scenes(id : 0x0005 ,Server) OnOff(id : 0x0006 ,Server) Level(id : 0x0008 ,Server) Private Cluster (id:0xfc31 ,Server, mfg-code:0x122f) Command Changes Modify the private command BindInitiator [cmd id: 0x04] to BindInitiator (endpoint) [cmd id: 0x04]. The endpoint supports input parameters of 0x02 and 0x03. 0x02 indicates EP2 enters Initiator, and 0x03 indicates EP3 enters Initiator. Other Changes Added Breeze Mode and Wind Down Sequence Mode (It only works in non-remote control mode + dimmer mode, that is, P52=0 and P258=0)	Fixed the inability to use Hold up/hold down to adjust the level of the binding device in OnOff + Remote Control Mode Fixed incorrect firmware version display Removed the ability to add EP2 to a group to multicast commands to group members Fix LED color not changing (Blue series VZM35-SN LED parameters don't take effect until switch is operated - #26 by jon) Match 2-1 red ramp rate behavior
