  • I'm planning on doing something similar with a $150 treadmill that uses an app called "Gymax." I don't want the app or its adorably embryonic social network. I just want three buttons: slow, fast, and really fast for 60 seconds.

  • Nice! I also got tired of the Withings app (which now pushes AI subscriptions, wtf) and "made" an app for the smartwatches (at least, it works with my ScanWatch 2)

    The app is at https://github.com/DavidVentura/withouthings - the firmware on the watch was leaked as well, and it's been helpful to debug some of the protocol.

  • Very light on details, but did awaken me to the idea that you can setup HW projects like this without soldering. Bluetooth is practically ubiquitous, and ESPhome does offer this up in a palatable way

  • You can build your own scale with an ESP32 for like $25 in parts - Hx711, load cells, ESP32, and a handful of trivial components. I threw together one that sits under my gas bottle, so I know when it’s running low. Adding impedance would be a pretty trivial step.

  • Withings has a full available API, I wrote a tool to just scrape what I need from the app at https://developer.withings.com/

  • How can you write (or have AI write) such an article without also sharing the code? Now it’s just a pretty useless brag, “look what I built”.

  • If you have a eufy scale, you can do this with no LLM needed - just set up an esp32 Bluetooth proxy, add it to home assistant, and then use the EufyLife integration someone already made. I did this recently with my scale to avoid having to sync it to my phone, go to the cloud, fetch data from the cloud, etc., and it's working fantastically. I have a little Home Assistant integration that pokes scale updates to a Python script running locally that provides a UI I like.

    Huge fan of running it this way.

    (Yesterday I ordered a more commercial, polished-looking esp32 Bluetooth proxy integrated into a smart plug - athome brand - but it's the same functionality, just in a nicer package than having a USB thing dangling from my outlet)

  • Using AI to reverse engineer undocumented Bluetooth protocols has been a godsend for me. We have an RV that came with a "Smart RV" system from BMPro that controls all of the lights, the air conditioning, starting the generator, leveling, slideouts, and other stuff.

    The BMPro app is... well, it's like they actively worked to make it terrible.

    I put up with it for 2 years and then had the bright idea to throw the APK at Claude Opus earlier this year. I now no longer have to use their terrible app as it reverse engineered the Bluetooth protocol and I can either use the custom-built Android app, website hosted on GitHub Pages, or the Home Assistant app I built using AI.

    It's not perfect, and it has bugs, but it is less buggy than their app. I've been busy at work lately, so I haven't had a chance to resolve the bugs, but I'll get around to it.

    I ended up also using Opus to patch the original APK to fix several bugs and inexplicably bad UI choices they made. I still prefer to use my own app, but I have the patched app as a fallback.
