I did the same. I wish dimmers would work.

  @Johnny_Bravo 

I just bought a new HS210 earlier this

month on Amazon. I was able to install just one HS210 on the load side and I got full control and feedback on the app in a 4 way situation. 

In the older units - I needed to install a HS210 on both end to make it work correctly in the app for the feedback. 

I am still struggling on the dimmers in a 4 way situation. 

I am still investigating. 

I have read these posts- but need a good diagram on splicing in a satellite where the four-way switch would be. I'm still a little confused on that.

Hope this helps you

  @jprah You need the HS210Kit or Single 3-Ways without dimmer.  I fought and lost with the Dimmable 3-Way.  The Dimmable version does not operate as a standard 3-way since it also communicates the dimmer status over the pair. The non-dimmable 3-ways work well with standard 3 or 4-way switches. I am an Electrician.

Yup that's whats what I did. Have 2 smart switches non dimmers and the original 4 way. Works fine just doesn't dim. 

  @smarcus3 For some reason, I can do the same with just one (HS210) 3 way installed and all works fine. 

  @Lman Has anyone else tried this with success? Using two kits?

My electrician just deleted one of my switches (we didnt really use it) and turned the circuit into a three-way dimmer and it works...needed the dimming function.
