If I'm looking at the same plug, it appears the Smart+ switch is wifi. This is where a z-wave plug may be a better option.
I have used many different z-wave plugs, mainly through looking on Amazon for inexpensive options. One of the best I have is the ZOOZ Zen25 double plug. Currently unavailable, but you can get it off ebay.
When you check the manual, there are advanced parameter settings which allow you configure most anything, including power loss recovery options.
I use the auto-turn-on timer as a remote reset for my network modem and hubitat - I turn it off remotely, and it will automatically turn back on after 1 minute. This is why I chose the zen25, it was one of the few plugs (including other ZOOZ plugs) that had the auto-on option. Many/(most?) z-wave plugs, however, have the power state restore option, including this one.
To set the advanced parameters, download/install the Basic Z-Wave Tool device driver from GitHub:
Then you can change the device type to the tool, use the tool to change the advanced parameter according to the manual, then change the device back to the normal device type.
