Okay, that seems to explain this. I changed the sleeping time to 20 seconds and sure enough, after about 10 seconds the current draw dropped down to ~7uA. So looks like I'm good now.

So what did I learn from this? Well... I better start reading the source code for MySensors :) Either that, or write my own lib so I know what is going on :)

Thanks for the help!

Oh yeah... Read the docs.. Yes, I probably should do that too :) Thanks!
