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 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.
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.
