Eaton RF9517DS ASPIRE RF Accessory Switch for RF9501 Wireless Light Switches, Desert Sand Finish

I bought these for a previous home. I received many compliments on them from guests and prospective tenants. I recently purchased them again for my new home. They look elegant, are easy to install and work without faults.

I got this to work with Smartthings. I really liked the style of the Cooper Switches but no matter what I tried I could not get these to work. There are 2 things that I need from a smart switch:1 - has to work when the hub is not2 - needs to be as quick as a normal switchThis add-on did not meet neither criteria. Without the hub, I could not get the lights to turn on. It seemed that the switch would not communicate with the master. After reading about the switches some more, I came to realize you need to purchase Coopers remote so that you can assign the add-on to the master. It could also be done with the Aeon remote. Secondly, with Smartthings, there was no device type that I could use to get a fast enough response to turn on the lights; where you turn on the lights from the add on and Smartthings told the Master to turn on.I tried multiple times to wire them accordingly and nothing would let this work. I had to give up on these and get the GE switches which were a breeze to setup in 3-way situations and met my 2 needs above.

only issue with it -- and not with the seller is that it's quite large (i.e. takes up a lot of room in the wall box) considering it only has the zwave module and power supply, yet it's the same size as the switch with the relay or triac in it.

I expect Cooper/Eaton to discontinue their z-wave products as the designs are pretty much rubbish. Can't keep them on the mesh and they are painful to exclude and re-join. Just go with the GE Z-Wave+ and be done with it.
