ZWave NODE 1: Node is DEAD

Hi!
I have deployed a fresh OH2 installation with only UI and ZWave 2.0.0 binding and got a lot of errors (here is the log: https://yadi.sk/i/vhM6M8g73BH5ek ).

The most strange are:

NODE 1: Node is DEAD //Node 1 is my AEON Z-Stick SUC
Node 255 not found!
and why is it constantly trying to poll information from battery-operated devices while whey are sleeping, generating tons of errors. I haven’t even added them as things yet.

Please advice! I was very happy with OH 1.x - it worked like a charm!
