Any clue?

[bcutter]

Please provide information on your specivic bluetooth environment: how are you trying to connect your toothbrush with HA? Are you using a Bluetooth Proxy (https://esphome.github.io/bluetooth-proxies/)?

You might want to have a look at this issue:

#14

[edwardtfn]

I'm not using any Bluetooth proxy and the toothbrush is just a 3 or 4 meters from the HA server, just at the next room.
I'm running HAOS under a quite powerful x86 machine.
All in latest versions.

So, I've teste getting quite close to the server and the toothbrush was finally discovered. 😃

Maybe support from Bluetooth proxy will be welcome then. I have a device in the bathroom that could be set as a proxy.
