I just played around with this nodeserver a bit and I  noticed if I press the "update EV status" in the main node (as opposed to the "Charging info" and the "climate info" node) it only updates the data inside that node.  I have to go to the "charging info" node and press "update system data" to get that node to update and then I have to go to the "climate info" node and press "update EV climate data" to get that node to update.  I can't imagine why it wouldn't pull all data if it is going to wake up the car... or is it waking the car?

is there a single/best command to use in programs to get the most up to date data?  and do some commands only get data from a server and others ("wake up"?) get them from the car?

a few more comments:

1  the "Honk" command now works on the first try (this was discussed previously).  Thank you.

2  the "steering wheel heat" variable data says "unknown/not installed" when I do have that option.

3  what is "auto conditioning" vs. "cabin preconditioning"?  which one is the one I'd want to turn on when I'm walking to the car to condition it NOW?

also:  word to the wise:  don't change the name of your car (in your car's screen), it will cause problems with some of the ISY settings that you'll have to work on to fix.  

Working on the update issue

Can you send a debug log with the heated steering wheel.  

I honestly don't know the difference on pre condition it is just available api calls  there is minimal documentation

Update updates all data - it is just not propagated to the screen.  In programming you should be fine.  I plan to remove the options on the other nodes and only keep status

I am having issues with publishing updates so this is why it has not been released yet
