@Harald_B If you read back you'll see they've said it is in the works now.

Can't wait to see what they come up with. I've been very impressed with the clever designs they've built over the years. Curious to see if it's a true 3 way dimmer switch design using traveler wires for communication, or rather a way to configure a regular HS220 into a slave controller. The latter would be pretty amazing as a firmware update and you can't beat the price recently on HS220s. But there is benefit when it comes to home control products that can work regardless of network access (harder to sell a house if it requires network access for some switches to work, etc).

Thanks for listening to your community!

Add me to the long list of those eagerly awaiting a 3-way dimmer.  The Meross MSS570 is a nice example, the features should include being able to change the light level on either side and including an LED in the switch so the switch can be found in the dark, the brightness of this LED should be programmable as they are often too bright, especially when watching TV or trying to sleep.

Add me to the list of those who are eagerly awaiting this product. 

@Carl please add me to this list. I need this and a fan controller to complete my ecosystem.

This is all I want for Christmas.  lol

Besides, I'm sick of hearing people tell me to just get a Lutron, or any other 3 way dimmer device to throw into my config.  Since I'm just starting with smart switches, I'd love/prefer to keep them all the same brand, for asthetics and simplicity. 

I would also like to request 3-way dimmers. I happen to have a house that had many 3-way switches installed and lots of them would be useful on a dimmer. Other brands have this so I think it's important to be competitive.

Yes, yes, yes!! Please make this product! it makes perfect sense to create a smart three way dimmable switch.

@echo954 I'm thankful I discovered this thread. I'm in the beginning stages of retro-fitting my home and earlier today ordered a 3-pack of the single pole dimmers to try out. I liked the clean look of the TP-Link switches and the price was fair. Rethinking it, I went back to Amazon later to order two 3-way dimmers to test, as well. A sinking feeling came over me when I discovered the 3-way dimmers didn't exist in TP-Link's line-up!! Fortunately, I eventually came across this thread (after researching a bunch of other smart switch makers) and talked myself off the ledge. While I don't have first-hand knowledge that these switches perform as advertised, I'm excited to give them a shot as I move my home into the 21st century. Thanks to everyone who has pushed to make this happen and the free-market forces that allow product innovation to occur!
