I make project to control Relay Node with switch node directly and not used gateway.
I use this code
MyMessage response (message.getByte(),V_LIGHT) ;
in this I set then switch node send data directly to relay node with ID 1
but if want send battery level or temperature to gateway, not to relay, then just set destination to 0 or need something else ?? other setting or code ..
and question for route .. if send data from node to node and distance is too long and I use repeater then also working or not ??
I thing so not ..
