@jkandasa said: Give me some hints, if you have any? ok, i go again with udp and node-red , i will send you back all i understood. 2 way for node , first in loop every 150ms max , listen udp port (i will confirm back). second , use async udp of menodev wich work fine for me. So that mean MyController maybe have to get also async udp to unmiss udp data. I meet some issue with broadcasting, because i created mesh in udp. Also i used ascii udp datagramm , basic but easiest way for me : something like "down|nodename|get|gpio1" "up|nodename|result|gpio1|0" "down|nodename|set|gpio1|1" Every node can read udp, so , it is very important to specify way and kind of action. Hope will help. Best regards.

OK, my mistake there. The Node // Firmware Name was empty. (It has been discarded when node has been deleted) [image: 1491227792128-capture.jpg] Now it works like a charm. Thanks for you attention.

@njbuch said: @Stephan35 Indeed but my voltage divider used was aiming for 0.0 - 3.3 and resulting output was over 1 volt most of the time, which means that I am reading 65535 all the time. I need a new one. I am looking in my bins after a few resistors that matches my photo-resistor specs. Will revert when successfull. I am using: http://www.ohmslawcalculator.com/voltage-divider-calculator to find the right combination. Sorry, answer is there : analogRead(A0) return 65535 You have to modify Myconfig.h #define ENABLE_READ_VCC

@Stephan35 Great!! good luck!, orangepizero is really great, and is powerfull enough to run mycontroller

@Stephan35 For now I do not find any wat to redirect.
