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?
The process for this is to obtain an EPS32 with bluetooth and wifi, pair it to the scale with bluetooth then keep it powered on in range of the scale, then the data goes into HA?
Yep, pretty much. Just get an ESP32 and not an 8266.
I have it plugged into an old Nokia charger and hidden in a cupboard to service all the Bluetooth temperature and door sensors.
When I use the scale it automatically sends the data to HA. Really convenient to use.
Which firmware did you load into the ESP?
Firmware apart what did you have to do?
ESPHome has firmware for the BT proxy:

The I installed the xiaomi app on my phone, I think it was called zepp life or something for the scale I have, you do the initial setup of the scale on there, and then it'll be picked up by the Bluetooth proxy.
