This is work in progress and did NOT work the last time I tried
Clone the repo as tesla_ble in esphome/custom_components
Add this to you device config:
external_components:
- source:
type: local
path: custom_components
# Set something like this to interract w/ the car
# First, use "Connect to car" to connect the BLE client
# If this is the first time, tap your card on the reader in the car to confirm the new key
# If it's already paired, no further action are required
# Then you can lock/unlock the car w/ the buttons below
button:
- platform: template
name: Connect to car
on_press:
then:
- esp32_ble_tracker.stop_scan:
- ble_client.connect: ble_tesla_id
- platform: template
name: Disconnect from car
on_press:
then:
- ble_client.disconnect: ble_tesla_id
- platform: template
name: Lock the car
on_press:
then:
- lambda: |
id(tesla_ble_id).lock();
- platform: template
name: Unlock the car
on_press:
then:
- lambda: |
id(tesla_ble_id).unlock();
ble_client:
- mac_address: AA:BB:CC:DD:EE:FF # Set you car BLE MAC address here
id: ble_tesla_id
auto_connect: true
tesla_ble:
id: tesla_ble_id
ble_client_id: ble_tesla_idWe're using a patched version of https://github.com/trifinite/vcsec-archive/blob/master/protos/VCSECv4.20.69.proto. A few patches are required because nanopb uses a callback mechanism when dealing w/ arbitrary data length/size. e.g. variable length strings, bytes, arrays. This makes it very impractical in our case. The (original author)[https://github.com/pmdroid/tesla-ble] of the BLE client also made a few patched I had reverse engineer, because he did not commit the proto file.
