Newbie Question - VRS15-1LZ

Just getting start with all of automation and Vera. Recently installed and paired a Leviton VRS15-1LZ. It seems to work fairly well no issues. Occasionally it says it loses connectivity, but when I click the switch in the iphone app it works just fine. Any thoughts? Any variables/parameters I need to change for it to work as best as possible?

What does the icon that looks like a plug and has an R in it stand for? This is what shows up for the leviton device.

the only thing I can think of is it’s to far away. If it works ok try turning off the polling, I don’t think you need it on this model.
