I think it's also worth to note that the swing will increase significant near the battery end of life. At least from what I've seen.

@TroyF The node device contains the information related to the Arduino-node such as battery level, library version and in the case of relaying nodes a clear button for relay information. On vera you cannot modify or add information to the standard devices.

My mistake. Was unfortunately cost few hours time for the search. For that I have won something overview in MySensors Code :)
