While not officially supported, it was so nice that the KS230 v1 kit could do more than 2 dimmer switches by combining a slave from a second kit. I converted all of my switches on the main floor of my house to Kasa last year, but I recently went to do my second level, only to find out that the KS230 v2 kit cannot use more than 2 switches on a given circuit. This means that I've had to disconnect any circuit that had more than 2 switches, which is many of the bedrooms and the main hall area. Please create a dimmer option with more than 3 way functionality, or re-release the v1 kit, as the v1 kit is nearly impossible to find now. While I love the Kasa products, this is a huge miss, in my opinion.
