Ok, so i switched my RS485 network to "bus". I desolder all of 120ohm resistors and have them only on both ends of the bus. RS485 to Ethernet gateway is in the middle of the wire. There are still some problems.. When I switching on the power and reading debug from gate I see that only 4 from 9 nodes are presenting. I need to reset other nodes manually to get them properly presented to the gateway. What am I doing wrong ? I need help I think.. Maybe its caused by the fact that all nodes powering on at the same time and there are many collisions on the RS485 bus ?? Maybe I should add some different delay() to setup part of my sketches to give, a time for every single node to present to the gateway ? Someone have successful working rs485 mysensors network here ?
This is code for one of my nodes with buttons, relays and temperature sensor:

I'm using OneButton library to get different actions when i'm clicking once, twice and holding buttons.
