legrand asvs12m4 sensa switch 600 watt single-pole or 3-way light switch with motion sensor manual on/off

I found these worked well. I didn't realize at first that the second multi-switch must the same model, not another model or a simple 3/4 way switch. I also found that the switch didn't work well w/o adjusting the time settings. The switch would either conflict or run into a race condition where both switched switched "off" at the same time and it sent both switches into a non-functioning mode - button didn't work at all. Resetting the switch (manually) or via a power-off, and power-on (breaker) appeared to reset the switches, and both would work once, and then go into a hung mode. Adjusting the timing of the switches via the documentation so that they were not using the default times from the factory, caused both switches to work great. I have not tried to connect the white wire to make the light work yet.
