Hi everybody,

i’m a developer too and also very interested in solving this use case. At the moment i consider to build up my own magic mirror, but it depends on some useful features i want to have a real benefit from it.

Actually i want to simply get the “start” and the “stop” signal from the brush to display a timer, which is stopped on “stop” and resumed on “start”.

Other features are more unnecessary sugar in my opinion. I’m using electric toothbrushes from Braun/Oral-B since about 20 years from now. I never changed the brush mode (if i had to, i could feel the mode. they are very various) and i’m ignoring the segmented Ring, the motivation Smiley and the star rating consequent 2 times a day.

2 years ago my toothbrush gone broken so i’ve got a new one. At this point i noticed, that both “Smart Guides” (that’s the shipped displays with Oral-B brushes) getting “start” signal from one brush.
This means there a no “pairings” or “syncs” between the smart guide and the brush. (maybe some days my neighbor will trigger this… :D )
Also my new brush is the first one advertising bluetooth integration. This leads to my assumption that “Smart Guides” not using bluetooth in anyway.

I’m not really experienced or well educated in electronic components, but maybe there is something like a proprietary radio antenna, waiting for a simple signal.
Maybe it’s possible to build up the same radio trigger with an antenna like the “Smart Guide” is using?

Any ideas if this would be possible?

Greetings
