see the buttons FAQ. They’re all listed there.
Ended up going with the Eaton Aspire Cooper RF9500 battery operated switch.
Notes, the big button is just one button. Doesn’t matter where you push it, it registers as Button1. The small dimmer switch on the side is 2 buttons. Down is Button2 and Up is Button3. Right now it doesn’t register hold button events (just button press), but I think the DT could be updated to handle that? It also doesn’t report battery life. That may also be available once the DT is updated, but I couldn’t figure it out.
