I finally grabbed a video of the delay I see with the setup I described in reply 24.
The setup has been very reliable but the delay when using the secondary switches is enough to be annoying.

I don’t have a great way to measure but a rough estimate is between 200 and 700ms of latency when I interact with a secondary switch before the primary reacts. It seems to be longer if the switches have been untouched for a several minutes.
It is enough of a delay that I’m going to swap it out for the GE Enbrighten Add-On Switches, which have no delay but don’t look nearly as nice:
@Eric_Inovelli I would LOVE it if the LZW31-SNs could use the traveler to communicate or if you were able to get an add-on with the LED strip available. We have 7 multi-way lighting circuits and they are some of the most heavily used. I’d love to have the LED indicator on all of them vs whichever junction box happens to have the Load wire in it.
