I am currently looking for a battery powered remote switch/button which can be mounted to a single gang (US) box. It will be used to control multiple lights in living room. I have a set of lutron caseta (wall mounted switch, pico and bridge) for my kitchen, I thought the pico was the perfect remote that I am looking for. But as we konw, pico does not work with ST (without middle-man).
I did go through the full list of buttons but still cannot find a suitable one. Cooper has a similar RF remote (RF9500AW I guess), but I am not sure if it could work directly to ST independently (without pairing to other wall mounted switch).
Since I have already had the Lutron bridge (not pro), I am thinking to add a set of lutron caseta plug-in switch. I could use its pico to control the plug-in switch and the ST could read the status of that plug-in switch for other use.
