I just purchased 6 of the Inovelli Z-Wave Switch’s of Amazon. 5 of them I had no troubles with and the install went really smooth. unfortunately not so much with the 4-way install (3 switches with light)
the first way I did it I just replaced the main switch with all wiring as is, and it kinda worked. I could turn the light on and off from the Inovelli switch, but if I used any other switch it would cut power to the switch itself… “No biggie” I thought maybe I have to change something. so I hit the ol googles and found the following wire schematic via [https://inovelli.com/nzw31-setup/other/] under 4-way. I then proceeded to rewire all 3 switches and changed out the 4-way switch to a 3-way as per the directions.
once i flipped the breaker back on I went and tested the smart switch everything worked. I then tested the dummy switches and POP!!! the smart switch had that unmistakable white smoke smell…DANG!! i verified and re verified I had the wiring right, and after the dreaded pop I checked again and double checked and it was exactly like the schematic mentioned above.
I then found this community while looking where I may have gone wrong, In here I saw others were successful in using this switch with the 4 way switch.
Any advice where I went wrong? and I guess i’m also out a switch
