Is there a True 3-way shelly relay?

Is there a way to wire a shelly/Sonoff or like device in a 3-way switch without having a live wire in the box? The Kasa HS210 works this way and was wondering if it is possible with any other product. Kasa will not fit in my scenario. I’ve looked and can’t find anything.

Bump… Is there nothing? Seems like a product gap/ opportunity to me.

Not a relay, but I am currently using a Feit 3-way dimmer switch with LocalTuya. Perhaps that might meet your needs (it’s comparable to the Kasa you brought up).

Thanks, this is the same as the Kasa, I’m looking for a relay with the same format as the Shelly devices that keep the original switch or use a standard non-smart 1-way switch instead
