there is no climate control command set yet, you 
can introduce one. Try to define it as common as 
possible, so it can be used for other vehicles as 

If you add the command set to the framework 
instead of the Leaf module, take care to also add 
a compiler option, as ROM space is very tight on 
the Twizy.

Chris, a german Twizy & Leaf driver, also prepared 
some Leaf images and asked me to add them to the 
Android App.

I can add a simple climate control UI to the App 
along with those images if you like.
