You asked for it. 
Please wait for the switch update to complete. It will sometimes take up to 10 minutes after the green firmware update notification finishes before the firmware file is verified and installed on the switch. Please do not cut power to the switch during this process.
If you have any problems with the update, please reach out to support so we can assist you with any issues.
2.10
Add parameters P54(Double down to value of P56)
Add parameter option 3 to P22(Switch Type) - Single-Pole Full Sine Wave
Add Disable Remote Control as special cluster command. Mfg specific command 0x10 (0x00 Enable Remote Control, 0x01 Disable Remote Control)
Fix the duty cycle value of dimming will be less than the Max Level value (miscalculation of max level when that setting is set)
Fix bug that was making set level “duration” not work correctly
Fixed excessive broadcast Report Attributes
2.11
Lower min levels are now allowed (only have neutral)
Fix Ramp Rate Remote Sometimes Not Being Applied
Add trailing edge dimmming in some cases. Trailing Edge dimming improves switch buzz and led bulb flicker,
Note: It is best to toggle Leading/Trailing Edge dimming in the Off state,
If you cannot control the switch under Trailing Edge conditions, power it on again or reduce the value of P10(max level)
When leading vs trailing will be used:
non-neutral + single pole (P22 = 0) Leading Edge
non-neutral + 3way(AUX) (P22 = 2) Leading Edge
neutral + 3way(dumb) (P22 = 1) Leading edge
neutral + single pole (P22 = 0) Trailing Edge
neutral + 3way(AUX) (P22 = 2) Trailing Edge
neutral + OnOff Mode + full wave (P22 = 3) full wave
2.12
Add parameters P55(Double Up to level)
Add parameters P56(Double Down to level)
Fixed incorrect behavior of P5
Adjust the output voltage under non-neutral
Optimize compatibility with dimmable bulbs
The mode is not automatically switched to “dimmer” when the user selects smart bulb mode.
Reduce unnecessary zigbee broadcasts
Optimize zigbee messaging network processing
2.13
Further optimized zigbee messaging
2.14
Add P25 (Increase non-neutral power output. This may cause flickering or aux switch problems with some bulbs. Adjust max level to fix this)
Modify P56 range 0 to 254 (allow double tap to turn device off)
Add P100(LED Scaling ) 0- VZM31 ; 1- LZW31
Add P123(Use different scene numbers via the aux switch)
Add P125(Send “move to level on/off” to bound devices that matches default level remote and local)
Optimized dimming flicker problem
The file has been sent to Hubitat (they still need to post it). I’ll be updating the z2m and zha firmware json feeds shortly. This firmware has been tested on a few dozen switches for a few weeks, but those that are cautious may want to wait a week or two before installing it.
