Shelly BLU motion triggering Shelly Plus Plug S - without cloud ?

Note: this question is about Shelly BLU motion, but the forum tag does not include that product. So i choose Shelly Motion 2 there.

Question:

I have managed to set up a Shelly BLU motion to trigger a Shelly Plus Plug S by configuring appropriate Scenes to switch the Plug on/off.

But this all requires the cloud. I would like a solution that works directly without cloud.

I also do not want this to require a home controller like Home Asssistant, but directly from BLU motion triggering the Plus Plug S.

I can do direct triggering without need for a controller or cloud from any Shelly WiFi switches for example to any Shelly Relay or Plug (have that running for a range of lighting). But i wanted the BLU motion for longer battery life and smaller size (i guess it would work with Shelly Motion 2, but i have not bought one).

Other lower-than-wifi power solutions like Z-Wave or HomeMatic IP also support that direct coupling.

Thanks for any information!

There is no local web interface or app-interface to do this for the Shelly BLU motion. Does this exist for any other blutooth only Shelly device ?
