@smartthing Currently ST does not support dual relay’s natively.
There are a couples threads on this now
ZWN-RSM2 - ZWN-RSM2 Create a new device type
AEON Power Strip - Zwave Power Strip from AEON
The first link is something I’ve been working on the last few days. IT’s still a bit buggy but I did get it working. The 2nd has info about the AEON 4 relay power strip and also mentions another dual relay switch.
My research all shows that this works with other controllers just not ST, my hope is the community can help is getting these working until ST supports them properly.
