REMINDER: This switch is only to be used to control lights (except ballasts or any lights connected to a transformer). Do not use the switches on outlets, fans, or any other inductive load.

In the, "Firmware Version" column, you can find the date code which will tell you what firmware version your switch was produced with. Date codes can be found on the top left of your switch
Firmware Version | Date Released | Enhancements Added | Bug Fixes | Notes |
Mar. 28, 2024 | Parameter Related Enhancements
Modified P55 by updating the range to 2-255 (was 2-254) where 255 sends an On command
Modified P56 by updating the range to 0-255 (was 0-254) where 255 sends an Off command
Added P120 which changes how a single tap on the switch works when the switch is used as a fan controller
Added P121 - Fan Timer Mode
Added P130 - Config/Favorites Button Binding Mode for Fan Control
Added P131 - Sets Low Level for Config/Favorites Button for Fan Control
Added P132 - Sets Medium Level for Config/Favorites Button for Fan Control
Added P133 - Sets High Level for Config/Favorites Button for Fan Control
Added P134 - Sets color for Config/Favorites Button for Fan Control
Button Related Changes
When in the local protection state, you can also restore the factory settings by using the normal method (ie: hold the top of the paddle down + the config/favorites button for 20 seconds)
Added a Combo Button to change P120
Added a Combo Button to enable Initiator Mode (which is used to bind the switch to the Blue Series Fan & Light Module)
If P121 (Fan Timer Mode) = 1, then the tap sequence is as follows:
Device Function Changes
Added a new dimming endpoint for the config/favorite button
Command Changes
Modified the private command BindInitiator [cmd id: 0x04] to BindInitiator (endpoint) [cmd id: 0x04]. This endpoint supports input parameters of 0x02 and 0x03. 0x02 indicates EP2 enters Initiator and 0x03 indicates EP3 enters Initiator
Other Changes
Removed the ability to add EP2 to a group to multicast commands to group members
Matched the Red Series 2-1 ramp rate behavior | Fixed the inability to use Hold up / Hold down to adjust the level of the binding device in On/Off + Remote Control Mode |
| |
Production
Date Codes: 2307, 2312 | Jul. 24, 2023 |
Modified P22 so that Single-Pole Full Sine Wave is the default
Modified when P22 is set to a value of 3, P258 will be automatically switched to 1 (On/Off Mode)
Added a Quick Tap Feature to show the firmware version
Added a Quick Tap Feature to switch to Leading or Trailing Edge | Fixed: Optimized issue where switches cannot join hub
Fixed: Optimized the transmitting power of the wireless signal | Officially added Leading / Trailing Edge parameter. |
Beta | Apr. 11, 2023 |
Modified P56 range 0-254 (allow double-tap to turn device off)
Optimized dimming flicker problem |
|
|
Beta | Mar. 17, 2023 | Further optimized Zigbee messaging |
|
|
Beta | Mar. 15, 2023 |
Optimized compatibility with dimmable bulbs
Optimized Zigbee messaging network processing | Fixed: Incorrect behavior of P5
Fixed: Adjust the output voltage under non-neutral
Fixed: Mode is not automatically switched to, "dimmer" when the user selects smart bulb mode
Fixed: Reduced unnecessary Zigbee broadcasts |
|
Production
Date Codes: 2303 | Feb. 10, 2023 | Minimum levels are better optimized w/neutral wire
Added Trailing Edge Dimming¹
| Fixed: Ramp Rate remote sometimes not being applied | Trailing Edge Dimming improved switch buzz and LED Bulb Flicker.
Please see notes at the bottom for limitations. |
Production
| Jan. 18, 2023 |
Added Option #3 to P22 (Switch Type) - Single-Pole Full Sine Wave
Added Disable Remote Control as a special cluster command (Manufacturer specific command 0x10 (0x00 Enable Remote Control, 0x01 Disable Remote Control)
| Fixed: The duty cycle value of dimming will be less than the Max Level Value (miscalculation of max level when that setting is set)
Fixed: Bug that was making set level, "duration" not work correctly
Fixed: Excessive broadcast Report Attributes | Single-Pole Full Sine Wave improves On/Off performance |
Production
Date Codes: 2211 | Nov. 11, 2022 |
| Fixed: Deployed a fix for the ability to send commands to group binding |
|
Beta | Nov. 08, 2022 | Removed the sending of multicast commands to avoid switches that would accidentally control other devices within a group | Fixed: Deployed a fix for the wrong destination endpoint used when sending some commands | 2.07 introduced a bug with group binding control and it is currently required that you use individual device binding. We recommend not updating to this version. |
Beta | Nov. 07, 2022 |
| Fixed: Deployed a fix for devices that are bound to the switch not using speed parameters 1-8 |
|
Beta | Nov. 04, 2022 |
