A new version of the node is now available 0.2.10 supporting the call limit - 3 wakes and 10 commands every 24 hours. Note, there is no need to wake the car to check data - data will automatically update once car is online and something changes. Car only needs to be wakened, if one wants to issue a command (assuming car is asleep). There is no dedicated wake command anymore - the commands will wake the car if asleep.
Tesla started charging for these calls (data and more importantly for commands and wakes). It is universal device paying for these calls, so the node is a subscription node to cover the cost generated by the node - cost is estimated based on typical data use.
