Tesla Fleet API pricing for TWCManager

[RichieB2B]

Tesla just announced that they will be charging apps for using the Fleet API from 01-01-2025 onwards.

I did some research what using TWCManager will cost me come 2025. I took November 2024 as an example month:

$ journalctl --user -u tesla-http-proxy --since 2024-11-01|grep "^Nov.*Received .* request for"|sed -e "s/.* request for //;s/\?.*//"|sort|uniq -c
      2 /api/1/vehicles
  25038 /api/1/vehicles/VIN1
    195 /api/1/vehicles/VIN1/command/charge_start
     78 /api/1/vehicles/VIN1/command/charge_stop
   1003 /api/1/vehicles/VIN1/vehicle_data
     53 /api/1/vehicles/VIN1/wake_up
  30505 /api/1/vehicles/VIN2
    178 /api/1/vehicles/VIN2/command/charge_start
     58 /api/1/vehicles/VIN2/command/charge_stop
   1524 /api/1/vehicles/VIN2/vehicle_data
    127 /api/1/vehicles/VIN2/wake_up

The announced pricing is:

/vehicles -> not charged
/vehicles/VIN -> not charged
/vehicles/VIN/vehicle_data -> device_data -> $0.002 per request
/vehicles/VIN/wake_up -> wakes -> $0.02 per request
/vehicles/VIN/command/charge_{start|stop} -> commands -> $0.001 per request

So my total bill for this month would be:

509 commands = $0.51
180 wakes = $3.60
2527 device_data = $5.05
Total = $9.16

Since Tesla grants each app $10 free usage each month for development purposes it seems I can keep using TWCManager for free.

The running costs for the current month (the bill for december 2024 will be waived) can be viewed on the Tesla Developer Dashboard.

Also: the default usage limit is set to $10 with $10 discount applied, so you won't actually be charged until you increase the limit and add a payment method. TWCManager will probably stop working when you hit the set limit.
