+# Import from tesla-apiscraper (also BETA)
+
+This is a multi-step process to export your data from a [tesla-apiscraper](https://github.com/lephisto/tesla-apiscraper) InfluxDB backend, convert it to a format that can be imported into TeslaMate (specifically TeslaFi CSV) while fixing up some typical data glitches the scraper produces, and then import it.
+
+## Requirements
+
+- A copy of the data stored by `tesla-apiscraper` - specifically the `/opt/apiscraper/influxdb` folder mounted in the standard apiscraper Docker configuration. **Create a backup of this** before attempting the export and conversion, just in case.
+
+- A system running Docker with sufficient RAM for InfluxDB to perform the CSV export. This does **not** need to be the same machine where API Scraper and/or TeslaMate was/is running - you can do the export and conversion on your PC/Mac. The important thing is to give the Docker machine more than 2GB of RAM, otherwise the InfluxDB export may fail.
+
+- **CREATE A [BACKUP](../maintenance/backup_restore.html) OF YOUR DATA** before attempting to import anything into TeslaMate. This is all highly experimental and has only been successfuly done once :)
+
+## Instructions
+
+### Part 1: Exporting the API Scraper InfluxDB data into CSV
+
+1. Download or clone the [tesla-apiscraper-to-teslafi-export](https://github.com/olexs/tesla-apiscraper-to-teslafi-export) repository into a folder on your machine.
+
+2. Place the `tesla-apiscraper` data folder *contents* (*data*, *meta* and *wal* folders) into the `influxdb-data` folder, next to the `influxdb-export.sh` file. The folder structure must look like this:
+
+   ```console
+   .
+   ├── influxdb-export.sh
+   ├── influxdb-export.bat
+   ├── (other stuff)
+   └── influxdb-data
+       ├── README.md
+       ├── data
+       ├── meta
+       └── wal
+   ```
+
+3. Run the `influxdb-export.sh` script (or `influxdb-export.bat` if you're on Windows). You may need to `sudo` it / run it in an Administrator command line prompt if your Docker install needs root. It will do the following:
+
+   - Create the `influxdb-csv` output folder, if it doesn't exist yet
+   - Start an InfluxDB Docker container with the `influxdb-data` and `influxdb-csv` folders mounted (on Windows, you may need to allow your Docker to access the drive you are working on for the mounts to work)
+   - Wait for the container to report as *healthy*
+   - Execute the export commands for all data stored by apiscraper, putting the CSV files inside the `influxdb-csv` folder
+   - Stop and delete the InfluxDB container
+
+   This may take a little while. After the process has finished, if there are no errors reported, continue with the next part of the instructions.
+
+### Part 2: Converting exported InfluxDB CSV files to TeslaFi CSV
+
+1. Obtain your Tesla's **vehicle ID** number. It's a 10- or 11-digit number that uniquely identifies your car, and is part of the TeslaFi data format, but it's not included in tesla-apiscraper data - so you need to source it separately. There are several ways you can get it:
+
+   - Manually using the Tesla API. The number is listed under `vehicle_id` in the `vehicles` response, as documented here: [https://tesla-api.timdorr.com/api-basics/vehicles](https://tesla-api.timdorr.com/api-basics/vehicles).
+   - From the database of another Tesla API tracker you're already using, such as TeslaMate.
+
+2. Run the `teslafi-convert.sh` script (or `teslafi-convert.bat` if you're on Windows). You may need to `sudo` it / run it in an Administrator command line prompt if your Docker install needs root. It will do the following:
+
+   - Create the `teslafi-csv` output folder, if it doesn't exist yet
+   - Build and start a Docker container with the `converter` app and its few dependencies, with the `influxdb-csv` and `teslafi-csv` folders mounted (on Windows, you may need to allow your Docker to access the drive you are working on for the mounts to work)
+   - Ask you for the vehicle ID mentioned above
+   - Process the CSV files in the `influxdb-csv` folder. This may take a couple minutes. Progress is displayed as the converter works its way through the files
+   - Stop and delete the Docker container
+
+   The finished TeslaFi-compatible CSV files are now located in the `teslafi-csv` folder.
+
+### Part 3: Importing the processed CSV data into TeslaMate
+
+- Proceed with the [TeslaFi import](teslafi.html) steps using the CSV files you just created.
+
+## Troubleshooting
+
+All of this is experimental and has not been extensively tested. If you encounter an error during Part 1 or Part 2, please create an issue in the [tesla-apiscraper-to-teslafi-export](https://github.com/olexs/tesla-apiscraper-to-teslafi-export) project on GitHub, since it's not directly related to TeslaMate.
