Should there be one command to turn on climate control and another to 
turn it off, or one command with a parameter for on or off?

The "command" I've added is just a #define in net_msg.h. There's no 
state or logic involved -- when you receive the command, wake up the car 
and send the appropriate CAN frame. If the car is already awake, it 
ignores the wakeup and message. So I don't think adding it to the 
framework is needed?

Having said that, the Nissan implementation of the feature sends the 
command can frame repeatedly for a while, and a "send this message at 
this frequency for this time" seems like something other cars might use?

Chris & I have been talking -- it turns out we both added Leaf images to 
the android app but I never got round to talking about it.

That would be great!
