Hello, here is what I currently have:

2 - 3way regular switches

want to add one more switch in a location, where I have only power ( no traveler wires)

Here is the plan

1. replace left 3way switch with HS210

2. keep right 3-way switch  as is

3. add HS200 into new location

4. create api python script that will monitor HS200 state, as soon HS200 state changes - make change to HS210 state ( if it on -> off, if it off -> on)

will this work?

or any other ideas?

thanks
