# fitbit-backup

fitbit-backup retrieves weight data from fitbit. So, if you have a WiFi scale

like the [Fitbit Aria](https://www.fitbit.com/de/aria), you can make a backup

of the weight data that Fitbit stores for you. Of course, this tool is not

restricted to just the Fitbit Aria — the data of any product which uses Fitbit

to store weight data will be retrieved.

## Installation

To download and compile, use:

```bash

go get -u github.com/stapelberg/fitbit-backup

```

Afterwards, run `$GOPATH/bin/fitbit-backup` to make sure it works (see below

for configuration). Once you get it to spit out weight data, install a cronjob:

```

0 19 * * * /home/michael/gocode/bin/fitbit-backup -oauth2_cache_path=/home/michael/.fitbit-backup.token.json > ~/weight/fitbit-backup-$(date +'\%Y-\%m-\%d')

```

This cronjob will download weight data from Fitbit once a day and store it in a

separate file. That way, even if one download fails, you will not accidentally

overwrite your old backups, and you can even notice when Fitbit loses some data

for whichever reason (hasn’t happened yet for me, but who knows…).

## Configuration

In order to talk to fitbit, you first need to create an application. Go to

https://dev.fitbit.com/apps/new and fill in the form like in this example:



Afterwards, fitbit will present you the “Client (Consumer) Secret” for the

newly created application. Specify that using the flag `-oauth2_client_secret`.

When running `fitbit-backup`, it will prompt you to visit a URL in your browser

in order to authorize the application to access your personal Fitbit account.

Point the flag `-oauth2_cache_path` to a writable file and `fitbit-backup` will

store the OAuth2 token in there. If you run `fitbit-backup` before the token

expires, it will be automatically renewed. Ideally, you only have to visit the

authorization URL in your browser once.

That’s it — now, when running `fitbit-backup` with all required flags, you

should get an output like this:

```

2013-07-30 23:59 65.3
