Shelly BLU devices without gateway

Hello,
I would like to know if to use the Shelly BLU family a gateway is required to be integrated into Home Assistant, or if it is possible to use the Shelly Plus Plug IT because I don’t find information of IT version but is “Plus”, that Plug have the possibility of being used as a Bluetooth gateway?
Can I connecting the Shelly BLU devices directly to the server’s Bluetooth as happens with the Xiaomi BLE without gateway?
Thanks.

The addition “IT” only says =“Italian standard”
so it is a Plus Plug S

Thank you very much, I will use it as a gateway.

Does the Shelly BLU series need a gateway or can they be connected directly with home assistant and BThome if near?
Thanks.

Unfortunately I can’t tell you that

I had started with the Shelly Gateway but I guess that they also work with an ESP Bluetooth Proxy

Yes, you need Bluetooth integration or BT proxy ESPhome/Shelly Gen2/Gen3 devices).

Thanks, I already have a Bluetooth integration with xiaomi ble and working.
In your opinion, the shellys BLU work without gateway?

This is not my opinion, this is a fact.
