@Carl

Thank you for the update. I've been waiting for years for a 3 way dimmer.

The sooner, the better.  I have heard the global chip shortage has impacted many products with some manufacturers delaying new product rollouts and causing supply issues with currant products.  Hope this is not going to affect the 3way dimmer rollout.

@Carl  We heard before that the 3-way smart dimmer was going to be introduced this spring. Now they are saying July or August? How Confident is TP Link that this will happen this summer? This development has taken a very long time. Other suppliers/competitirs have achieved this, so this is not new technology.

@Diesel1122 You don't have to wait for Kasa to release a 3-way dimmer. You can use the Smart Actions tab in your Kasa app. I replaced two traditional 3-way switches with a Kasa dimmer and a Kasa 3-way. After I installed them I was disappointed that they can't be paired by holding down the switch for 5 sec. like the 3-way instructions said. I then realized that this is a software problem. If you go into the Kasa app, click Smart Actions, press +, select "control with a switch". Then you select the first switch so that when it's on, the second switch will also be on. And set up another smart action for the reverse direction. Tada! You've got a 3-way dimmer with no waiting for Kasa to launch one!
Note: in retrospect, I may not have needed a 3-way switch, just a regular single pole since the software logic is what controls the switches, not the wires. HTH.

Ok lets admit that we do not want to wait and well we do want to replace a pair of three way switches, what about a TP-Link compatible alternative?

Given you have a TP-Link dimmer switch (single pole) and a TP-Link switch (single pole not a dimmer).  At the hot side you wire the dimmer switch to hot and one of the travelers.  At the other side you wire the same travler wire to the light.  You now have a single dimmer controlled light.  Now install the TP-link single pole switch (not a dimmer) in the remaining location and just connect it to hot and white nothing connected to control.  Now you add both switches to your system and bind them together with Smart Action.  The result is that when you press the non dimmer switch it will turn on the dimmer switch (or off) and the same on the other end but the dimming is only controlled by the dimmer.

Hope you get this.  You are doing the travler binding in software.

Note:

Since you can assemble 50 smart actions but only have 3 that actually are on-line it may depreciate this approach.  The 3-Way dimmer is truly the only real solution

@Carl Apparently.... after more than 2 years, your developement team is most certainly not listening about a 3-way dimmer, nor are they producing anything of the sort.  I have put a lot of money and time into your products.  Is this how you retain customers?  We're feeling quite ignored!
