Hi all, since 25th january i have a really strange behaviour.
Here you can See a Video:
This is my Setup:
Arduino Mega 2560 clone with 18 Relais and 11 Doorcontact wired
and now the problem. After a random time sometimes 1 day, sometimes just 20 minutes the arduino led rx,tx are flickering very wild and the relais are also flickering. the behaviour looks very uncoorinated, the homeduino does not work at this time, i get no error (debug: On) in pimatic, the cpu goes from 16 to 30. after that i have to restart pimatic. the arduino has a quality power supply (12V)
i have changed nothing on my setup. all work fine before that for a half year.
i switched the usb serial cable to get sure this is not the problem, also flashed the homeduino new.
what i mean with flickering is the relais goes on/off really wild and just for a short time.
i hope someone can give a hint to fix this as fast as possible.
Thank you all.
