I've had a fitbit wifi bathroom scale for a while. Getting the data out got suddenly more difficult when Google bought them, and I didn't love giving that data to google. It's finally died, and I'm looking at replacement options.

In a perfect world, I could just go to a store and buy a "HomeAssistant Ready" scale. If I can't have that, I'd like a scale that is on my local network and exposes the last x weigh-ins as an API on the device, then I could write something to poll it.

I haven't seen anything like those, but have turned up:

  • a project to decode the bluetooth transmissions of a number of scales (after you build an ESP32 device for it)
  • the Withings cloud based scale, but with a well documented API

Any other good options?

I have a Wyze scale, it's well made and easy to export the data via email automatically.

I got a Xiaomi scale 2 (years ago) and that works with the OpenScale app. It's Free Software. There is a list of supported bluetooth low-energy scales by that project/app.

Wait what I thought this was satire at first

you can't even poke fun at selfhosted people anymore because someone WILL 100% spend 48 hours straight 3d printing and programming a toothbrush

That would be a fun thread. What’s the most unnecessary self hosted thing you’ve seen someone host or host

I thought this one was dumb too https://lemm.ee/post/49060797

I think looking at openscale would be worthwhile:

https://github.com/oliexdev/openScale/wiki

Looks like it can push to mqtt? Huh, that's new to me.

Also, if you want HA, there's this:

Good luck!

If you can find an old working Wii Fit Balance Board you can use it as a very accurate Bluetooth scale.

[–] peregus@lemmy.world 3 points 2 days ago (2 children)

Did you do that?
If yes, could you share some info about it?

[–] curbstickle@lemmy.dbzer0.com 3 points 1 day ago

Looks like a few folks have

https://github.com/schellingb/WiiBalanceScale

Going to have to try this out myself!

It's interesting how old console tech comes back around to be useful for other stuff. I've used a couple Xbox Kinects to do 3D scanning and with an augmented reality sand box.

[–] B0rax@feddit.org 3 points 2 days ago

Really? That’s a good idea.

[–] possiblylinux127@lemmy.zip 8 points 2 days ago (2 children)

Can you just get a normal scale? I just have a mechanical one from the last century

[–] interdimensionalmeme@lemmy.ml 2 points 1 day ago (1 children)

How do you automatically compile the daily readings into an excel file with graphs? Raspberry pi running opencv sending the time series to influx db and then grafana generate graphs for you home assistant health monitoring dashboard, along with the blood pressure monitor, continuous glucose monitor, pee ketone content, the pills dispenser and the rest of your fitness regimen?

[–] possiblylinux127@lemmy.zip 1 points 1 day ago (1 children)

I don't know what you are trying to say. (Your sentence is a run on)

[–] thirdBreakfast@lemmy.world 15 points 2 days ago (1 children)

I mean, yes, I could. But I'm committed to the #selfhosted life where I spend hours building unnecessarily complicated systems to make my life easier in small ways.

[–] possiblylinux127@lemmy.zip 2 points 2 days ago* (last edited 2 days ago)

It just feels like a very dark reality

[–] Rivalarrival@lemmy.today 40 points 3 days ago* (last edited 3 days ago) (4 children)

I use Tasker to log my weight to a Google Sheets spreadsheet, and just use a dumb scale.

The only piece of technology in my house is a toaster from 1982, and I keep a loaded shotgun next to it just in case it makes a noise I don't recognize.

(Am I doing this right?)

[–] socialmedia@lemmy.world 3 points 2 days ago (1 children)

What if the shotgun makes a noise you don't recognize? Hit it with the toaster?

[–] Rivalarrival@lemmy.today 3 points 2 days ago

If my shotgun starts making strange noises, I check the brownies.

I can't help, I wish I could, but I'm curious. Why a smart scale? Why not just any dumb scale from Bed Bath and Beyond?

[–] thirdBreakfast@lemmy.world 4 points 2 days ago

I like data, I like tech, I like investing large amounts of time and energy to self-host things that muggles would not bother with.

[–] Joelk111@lemmy.world 4 points 2 days ago (6 children)

I'd guess automatic history tracking. Step on it every morning and it'll automatically save your weight to Home Assistant or whatever so you can see if you're gaining/losing over time.

[–] ArcaneSlime@lemmy.dbzer0.com 3 points 2 days ago* (last edited 2 days ago) (2 children)

I suppose that makes sense, honestly I just go with "more/less than last time" lol. If I went more in depth with it I'd probably use a pen and paper.

Cumulatively pen and paper will add up to more effort. And I would person give up at some point. It would probably never enter my daily jabits. Realistically if on the scale everyday, the changes are so minute you won't notice the monthly and longer duration trends.

It's really surprising there isn't a no bullshit option you could just buy

[–] Joelk111@lemmy.world 2 points 2 days ago (1 children)

I don't keep track of my weight so I could be wrong here, but more/less than last time wouldn't be very helpful as your weight can vary by the day. You need a trend over weeks to really see what's going on. I definitely wouldn't use pen/paper as it's just too much data to organize and graph, but excel would be a reasonable alternative.

Body fat tracking etc

[–] sunstoned@lemmus.org 6 points 2 days ago* (last edited 2 days ago)

OpenScale works great and kind of does what you want. If you have an old Android phone laying around you can have it persistently connected to a cheap Bluetooth scale. Functional, but at a much have higher power cost than an ESP32 solution. Automated database exports to a local file (on the android device) and Syncthing can move your data around for analysis.

The good folks over at Gadgetbridge might have a solution too, although their list of supported scales looks pretty short.

You might also look into making a project like rmfakecloud to trick your Fitbit device into pushing data to a local server.

Not sure about home assistant though, I've never used it.

[–] restingboredface@sh.itjust.works 20 points 3 days ago* (last edited 3 days ago) (1 children)

I have a withings and I really like it. Their privacy policy made me feel better about allowing my info on the cloud. You can run it offline (it sends weight via Bluetooth to the app but won't show 7-day trend an scale screen without wifi). I don't mind that, so I leave it disconnected. I don't use a home assistant though so I can't speak to that part.

I have the withings watch also, so I use the app as my catch all health tracker which works well. it's nice to have everything together. Can't speak to any others but I'd recommend withings.

[–] rumba@lemmy.zip 10 points 3 days ago

I went from Fitbit to Withings, that Fitbit scale was nothing but pain. Every time my battery started getting low it would disconnect from Wi-Fi and I have to re pair it. It was inconsistent, If you pick it up and move it a foot to the left you get a completely different reading than if you just leave it where it sits. Because of the messed up fluctuations, It constantly identified the wrong person in the house.

Had the Withings scale for 4 years now and it's just been fine.

[–] fmstrat@lemmy.nowsci.com 15 points 3 days ago (1 children)

I zoomed in on the screen because I just assumed this was a meme.

It doesn't sync to homeassistant, but I use a Xiaomi scale with openScale off of F-Droid. There's a few different scales supported: https://github.com/oliexdev/openScale/wiki/Supported-scales-in-openScale

[–] hummingbird@lemmy.world 1 points 2 days ago

I also use openScale from F-Droid, in combination with this Bluetooth scale:

I don’t have any options for you but make sure you get one that doesn’t use battery when not in use. It’s really annoying replacing those little coin batteries all the time even though you only use it like .001% of the time

[–] Geologist@lemmy.zip 7 points 2 days ago

Not local, but I’ve been using my withings scale for at least 5 years, and I sync the weights with its home assistant automation from the withings api, then plot the data on a custom health dashboard I made.

I’d love a local alternative, but regardless I haven’t had any problems with my setup.

[–] stalfoss@lemm.ee 3 points 2 days ago

I’ve had a withings scale for like 5 or 6 years, use trendweight.com for a graph, I haven’t had any problems with it besides replacing the batteries every year or so

Where's that meme about tech enthusiasts and tech employees with a printer gun, where does this guy fall

[–] taaz@biglemmowski.win 7 points 3 days ago

Quick google search it seems your only options for HA are Xiaomi scales with bluetooth paired to a mcu with esphome.
