I have 4 Leviton z-wave (DZ15-S) smart switches that have stopped functioning as switches. The still connect to the network, but the relay inside the switch is either stuck on or off (I have both scenarios). Are there any good uses for these? I’ve considered putting them all in their own box and using them as scene controllers. I should clarify that Leviton has replaced 3 of the 4 switches under warrenty, but I am switching to Zooz switches going forward
