Installation
Docker (recommended)
The recommended way to install and run TeslaMate is to use Docker. Create a
docker-compose.yml file and replace the necessary environment variables:
version: '3'
services:
teslamate:
image: teslamate/teslamate:latest
restart: unless-stopped
environment:
- DATABASE_USER=teslamate
- DATABASE_PASS=secret
- DATABASE_NAME=teslamate
- DATABASE_HOST=db
- MQTT_HOST=mosquitto
- VIRTUAL_HOST=localhost # if you're going to access the UI from another
# machine replace "localhost" with the hostname
# / IP address of the docker host
ports:
- 4000:4000
cap_drop:
- all
db:
image: postgres:11
environment:
- POSTGRES_USER=teslamate
- POSTGRES_PASSWORD=secret
volumes:
- teslamate-db:/var/lib/postgresql/data
grafana:
image: teslamate/grafana:latest
environment:
- DATABASE_USER=teslamate
- DATABASE_PASS=secret
- DATABASE_NAME=teslamate
- DATABASE_HOST=db
ports:
- 3000:3000
volumes:
- teslamate-grafana-data:/var/lib/grafana
mosquitto:
image: eclipse-mosquitto:1.6
ports:
- 1883:1883
- 9001:9001
volumes:
- mosquitto-conf:/mosquitto/config
- mosquitto-data:/mosquitto/data
volumes:
teslamate-db:
teslamate-grafana-data:
mosquitto-conf:
mosquitto-data:
Afterwards start everything with docker-compose up.
Open the web interface at http://ip-of-your-machine:4000 and sign in with your Tesla Account.
To access Grafana go to http://ip-of-your-machine:3000.
Optional: To switch to imperial measurements open the web interface,
navigate to Settings and tick the checkbox.

Docker
Run docker-compose pull and restart with docker-compose up.
Manually
Web Interface
There is a basic real-time web interface. Once the application is running locally, you can access it at localhost:4000.
MQTT
Unless the MQTT feature is disabled data is published to the following topics
($car_id usually starts at 1):
teslamate/cars/$car_id/display_name
teslamate/cars/$car_id/state
teslamate/cars/$car_id/battery_level
teslamate/cars/$car_id/ideal_battery_range_km
teslamate/cars/$car_id/charge_energy_added
teslamate/cars/$car_id/speed
teslamate/cars/$car_id/outside_temp
teslamate/cars/$car_id/inside_temp
teslamate/cars/$car_id/locked
teslamate/cars/$car_id/sentry_mode
FAQ
Sometimes the first few minutes of a trip are not recorded even though the car was online. Why?
Ideally, TeslaMate would frequently scrape the Tesla API – 24/7. However, the vehicle cannot fall asleep as long as data is requested. Therefore TeslaMate suspends scraping for 21 minutes if the vehicle idles for 15 minutes, so that it can go into sleep mode. Consequently, if you start driving again during those 21 minutes nothing is logged.
Solution: To get around this you can use your smartphone to tell TeslaMate to start scraping again. In short, create a workflow with Tasker (Android) or Shortcuts (iOS) that listens for connected Bluetooth devices. If a connection to your Tesla is established send an HTTP PUT request to your publicly exposed TeslaMate instance.
(With iOS 12 and below workflows are quite limited but can be triggered manually. iOS 13 will probably fix that.)
PUT https://teslamate.your-domain.com/api/car/$car_id/logging/resume
PUT https://teslamate.your-domain.com/api/car/$car_id/logging/suspend
I strongly recommend to use a reverse-proxy with HTTPS and basic access
authentication when exposing TeslaMate to the public internet. Additionally
only permit access to /api/car/$car_id/logging/resume and/or
/api/car/$car_id/logging/suspend.
