This might be a very noob question, but it's my first time trying to connect a device via Bluetooth.

I got a LD2410B, and powered it via a USB C cable. All I know is that it's powered, because the sensor gets hot. Followed this. https://github.com/jonnybergdahl/Sensor_LD2410B

I've always had a Realtek Bluetooth Radio integrated, which is from my HA host, a miniPC. But I've never used it or know how to. All I can do is click on Configure, and check Advertisement Monitor, where it shows a list of devices without name (a couple of them with name that I recognise). But I don't see the sensor showing up, or if it should at all. Or maybe it is but with no name, so idk.

I'm quite close to the host, like 3m, no walls.

No new integration is picked up by HA though. I've tried manually adding the LD2410 integration and it says there's no device in the network.

So... what's the process? I don't really get how this is meant to work.

It's best to setup a bluetooth proxy https://esphome.io/projects/?type=bluetooth because i think your buildin bluetooth is not receiving anything.

I've seen that, never done that before, and I feel it's overcomplicating things. At least for testing.

#

I mean, it receives "something", from things way further (scale in the bathroom on the first floor)

#

I just don't know what.

If you have done it right homeassistant should notice your sensors.
