eufree: Smart Scale Data Freedom

I bought a eufy Smart Scale back in 2017, and it’s still working great almost ten years later! But, I don’t like having to set up an account with eufy to record my weight history. Here’s an unedited note I put in my password manager that cracks me up:

I think this is the password I used to set up my scale on my phone. I have no idea why I need this password, but it probably makes sense to hold onto it.

I created eufree so I would have an easy way to record my data without getting sucked into the eufy ecosystem. I also set up a TRMNL plugin so I could display my weight on my TRMNL. Here’s how I use the system:

1. Start eufree at the command line:

   eufree --trmnl-url "https://trmnl.com/api/custom_plugins/asdfqwerty1234"

2. Step on the scale to weigh myself.

3. When the scale settles and sends its final reading, eufree logs that data to a file and sends my weight to my TRMNL plugin for plotting.

It feels great to be in full control of my data!
