Hello,
did anyone find a way how to start remote preheat via can commands?

Can you explain the scenario on how that would be useful?Hello, did anyone find a way how to start remote preheat via can commands?
And how exactly do you communicate with the raspberry without a cellular connection or wifi?..... If you can do all that and get it to work and make the front end, you need to sell it. you'll be rich and people will dump onstar and flock to you.
Actually all you need to do in theory is see what message the remote receiver module floats onto the bus and dup that with the Pi.You can do it, but it won't be what you are looking for. You can use a raspberry pi with a wifi module or BT module to interface with the obd2 canbus. The car will "sleep". you'll need to either spoof the keyfob ( if you need to ask, it's beyond you ) events from the controller there or leave a key in it and do a full start stop cycle. If you can do all that and get it to work and make the front end, you need to sell it. you'll be rich and people will dump onstar and flock to you.
I said you'd need wifi or Bluetooth. You can get 3G/lte modems or a hotspot. the convenience has its price.And how exactly do you communicate with the raspberry without a cellular connection or wifi?
I use Onstar to warm up / cool down my car as soon as I can turn on my phone upon landing in an airliner.
The car is miles away in the huge economy lot, (plugged into an L2.Yay !!) with no wifi for miles.
How could a raspberry/spoof do that for me?![]()
I'm aware of it normally but the car and the can bus goes to sleep. you can't send messages once that happens. The keyfob receiver and on star are connected via a backdoor on a separate gmlan to wake things up. You have to use that, or have a keyfob in the car or present a signal and "start" the car to wake the bus up.Actually all you need to do in theory is see what message the remote receiver module floats onto the bus and dup that with the Pi.
>So if you are within "wifi or Bluetooth" distance from the car, at most, a few more steps and the Key Fob works.>I said you'd need wifi or Bluetooth.
