Auxiliary Switch Support

I’m replacing my Lutron Caseta switches with Inovelli Blue-series but want to keep the Lutron accessory switches for my 3-way and 4-way setups ( I have over 20 lutron aux switches). I saw a post from 2019 that Inovelli was testing the Lutron accessory switch. Would this configuration be possible? I don’t need to keep dimming functionality at both ends as long as I can turn on/off on both ends even with blue-series on smart bulb-mode.

I actually tried using the Caseta aux switches since they’re what’s available from Home Depot and they don’t work. Firstly, they don’t work how the recommended Embrighten aux switches do. Embrighten aux switches are powered through neutral and just sends a signal down the traveller wire and doesn’t touch the line or load wires at all. Caseta aux switches actually hook up to line and load… but not neutral. When I hooked it up anyways, its behavior was completely abnormal. In aux mode, pressing up triggered config, pressing down did nothing. Dumb switch mode was more fun, holding up triggered down, and the neutral position was read as pressing down.
