Thanks @Carl !!   This is great news and is keeping me from going with another brand for our new home build. Purchasing a total of 42 smart switches, only 5 of which require a 3-way dimmer...but this was a make it or break it situation as I was not going to use two different types of switches. This announcement kept me from going with a competitor's product, so thanks again!

With that said, is there any rough estimate as to when these might be available? Or any documentation that can be shared at this time for requirements? For example, I assume we can pair one 3-way dimmer with a standard "dumb" switch for the other switch location, just like we can do today with the HS210 3-way switch? Anything that can be provided would be very so we can plan electrical rough-in accordingly.

THANK YOU!!!

@Carl thank you again!  Please let me know if you need any beta testers or any way to get my hands on the switches any sooner.  I'm a product manager in the tech space so if there are any opportunities for beta testing please let me know and I would be more than happy to assist if there is an opportunity to do so.  

@funkhouse9 I didn't think you were being critical either. It makes sense to be forward thinking particularly about no neutral. I would guess that a good 15%+ of the homes in america have no neutral and you're cutting them out completely from smartswitches requiring one. I to had noticed a few competitors coming out with a no neutral required but I figured it was best not to push it to much here, baby steps, lets just get a switch out type thing! LOL.

@jb510 even though it may be in the code there are a few instances where they still don't require it, or at least did not up until recently. Our house is 7 years old and the switch by my garage does not have one. My father-in-law who was an electriacian told me why it probably wasn't needed but I've since forgotten. We figured we could drill through the stud next to it and tap into the outlet down below it for a neutral it it ever came out.The Lutrons are nice and seem to have good functionality. I was never a fan of the layouts, the switches just always seemed busy to me. 4+ big buttons plus the dimmer leds. I liked the sleekness of the one main button on Kasa. I always thought, I like the dimmer function(which is why we are discussing here) but I use it a lot less than the main on/off so I don't need the huge dimmer button like on the lutrons.

Don't one of the competitors you had referenced work on bluetooth to keep the radio power pretty low via battery? Seems like Schlage also had a bluetooth option for this reason but I would have to dig back in to confirm.

@KleyP I second the 4way and I mentioned way back I've got at least 2 of those locations and would have a 3rd once installed in my basement, maybe a stackable type system, 3way+1. Seems like once you get past the 3-way setup that one more would be no big deal. But again, given this glaring hole that it took this long to fill I'm not holding out for a 4-way option. 

Anyways, cheers everyone. With any luck I can tell the family to put several sets of these for me under the Xmas tree!

@KirkMeyers Do you use Alexa? If I understand what you are asking I believe you can set a routine in Alexa to handle that. I have one that turns on my bedroom dimmer in the morning at a predefined dimmer level. You can even ramp it over time. I would think Google platform would have a similar feature.

@Wolfpack98, I haven't connected my Kasa switches to Alexa yet.  That could work as a further workaround, and I will try it.  Thanks for the suggestion.  I do think the more intuitive solution would be to be able to group dimmers to control each others dimming levels (I can already create a Smart Action to group on/off control, so dimming control is just an extension of that functionality.)

TP LInk really needs to develop and release a 3-way smart dimmer switch. I have observed that TP Link does not appear to have this product actively in development. This is a major missing link in the smart Kasa group of home lighting control. I have multiple locations in my home where I would use this product, but for now I have to rely on Leviton for this functionality. I would prefer to work with one supplier for all my switches and outlets, but TP Link is letting me down in this regard.

@SteveSJ Have you not read the previous 9 pages on this topic? I'm not jumping on you but that was teh whole discussions for the first 8 pages. I'm with you, I was one of the first to jump in here as well a year ago. But on page 8 or 9 I think the TPLink moderator has mentioned they are now developing this and will probably be out around year end. Been over a year since I brought it up, so sometime under a year to go. I agree, for TP-Link who seemed to be at the forefront of smarthome tech for the average person for a while, they have really rested on their laurals lately.
