Following. I've really been looking forward to this release. Hopefully in time to install in our new home that's currently being built.

FWIW: Assuming the KS230 is using a PLC technology as it appears (if not, let me know and I'll delete this post as misinformation), the following is from a troubleshooting guide for an energy monitoring device (https://www.theenergydetective.com/downloads/issue1.pdf) that uses power line communications:

There are several things that can cause communication problems:
a) Noise on the power line. Today’s homes usually contain numerous devices capable of producing
noise on the power line. These include fluorescent lights and ballasts, halogen lights, UPS backup
power supplies, unfiltered dimmer switches, and fan speed controls and A/C–D/C power supplies
for fax machines, computers, televisions, printers, WiFi devices, and numerous other electronic
products.
b) Faulty wiring can cause large resistance in the power lines between the Gateway and MTU. This
problem is frequent in older homes, homes with aluminum wiring, and homes where the wiring path
from the MTU to the Gateway is long.
c) Devices on the power line that absorb communication signals. These include surge-protecting plug strips,
TVSS devices, power factor correction capacitors, and power supplies containing large capacitors.

Hopefully the above can help customers identify "stuff" that may contribute to the problem.

FWIW2: Depending upon the PLC technology used, the troublesome stuff may not need to be on the same circuit breaker.  Intellon has a white paper mostly on point: http://www.sws.cz/prod_img/digitus/plccrossphase.pdf

All of that is true and may be at a neighbor house sharing the same step down transformer.

Things that also share the Power Line Communication sphere are:

solar panel micro inverters (enphase)

X10 switches and controls

Plug in lan extenders 

plug in intercoms

and more

Fabulous! Just installed and tested, and so far so good with firmware 1.0.9! I will leave the lights on full for a while to see if there are any disruptions, but so far it is behaving perfectly without any of the shutting off at higher brightness settings. Great work to your devs in resolving this so quickly, and thanks for keeping the attention on this, Carl.

As stated before, previously, mine would shut off at around 40 or 50% dimming or higher. And now they work exactly as expected, showing Firmware 1.0.9 on the app after the Windows 10 upgrade tool was run. Hopefully we can get some good solid early success so that it can be rolled out to the main app updater for an easier upgrade.

Thanks for the update! I also tried the new firmware and in my brief testing, it seems the issue is resolved for me as well! Lights stay on, dimming works as intended, and both switches are fully functional.

Excellent turnaround time in my opinion. Thanks for getting this fixed in such a short time!

This is not working for me.  The PC I'm using is a work computer, so there are likely security restrictions that are preventing the scan from finding my devices.

The instructions mention that a MAC version of the upgrade tool exists.  Can someone please post the MAC version?  Alternatively, can this simply be posted to the app?

Please advise.  Thanks, Rich

Hi @Carl, 

I've had my switches for weeks, but was waiting on the thumbs-up from you.  I installed the kit this morning with minimal effort since I was replacing existing Lutron multi-location dimmers.  The installation was flawless with one exception.  Because the switch shipped with the older firmware, the setup process asked to calibrate the switch first.  My lights went to full bright and then immediately dimmed to off like everyone else's.  Then I was stuck on a "broken" calibration screen.  The lights wouldn't adjust or come on at all.  I was finally able to skip the calibration step and move to updating the firmware which worked fine.  Now the switches work perfectly and I was able to go back and do the calibration.  It seems to me that the uninitiated and those unaware of the firmware issue will be very confused and assume the switch is bad if they continue to ship with the original firmware.  I would suggest sending an installer update that prompts to update the firmware first before moving on to a final calibration step. Just my two cents.

Thanks for your support and communication.  Few companies would have anyone this dedicated on the front lines.  I'm glad I switched to TP-Link and that I waited patiently for the 3-way dimmers.  How about motion sensors now so I can get rid of all of my Lutron switches?  :)
