Greenwave NP310-F and openhab2 RC1

Hi All
I try to use greenwave NP310-F PowerNode (6-plug.
Openhab2 shows GWPN6 Multi-socket PowerNode (6-plug) I hope is the same.
I have I few problems with this device.

  1. Openhab2 shows 7 nodes… switch, switch1,…switch6 but devices has only 6 switches…
    2.After openhab2 restart openhab2 shows all switches off
  2. Electric meter (watts) and (kWh) update very, very slowly and no for all nodes

Anyone has experience with this device under openhab2 ???
