LZW31-SN 4 way switch not working correctly

Well I can tell you I’ve had some interesting trials going through setting up 4-way and 3-way switches using all LZW31-SN’s for each switch. For both what I was able to get working was leaving parameter 22 alone. I reset all the switches, then joined one by one. Then got them all to talk using the zWave Association tool the 2 line dimmers with the 1 load dimmer. For the 3 and 4 way you need Groups 2 and 4 for each Line Dimmer configured like this…

Line Dimmer 1 Source --> Load Dimmer Destination
Line Dimmer 2 Source --> Load Dimmer Destination

Hope this helps

So I had the same problem and I made a change and it’s fixed. I really don’t know what this change does other than fix the problem we are both having. What I did was unable the default Z wave toggle. See picture. Try that and let me know if it works. I also went into the smart things IDE website and made sure the parameter 22 was set at one and also performed a save from the website. After I did those two things the switch worked and continues to work from any of the three locations.

I had a similar problem with my switch. I set param 22 to value 1 through my z-wave bridge multiple times and it simply didn’t take until I set it locally through the switch.

What is strange is that according to my z-wave logs, the switch appeared to have successfully set the parameter via z-wave:

Despite the logs purporting to show the value of parameter 22 to have already been set (old value=1), the switch did not function properly with my existing 3 and 4 way switches until the parameter was set locally at the switch.

Could this be a firmware bug? I have had no issues setting param 22 for momentary switches in the past, but this is the first time trying to switch it for a 3 way toggle and having it clearly be ignored when done over z-wave.
