its exactly as you guys say. taking a mega solves my issue and thats fine. i work with arduinos for many years now but its the first time i ran out of storage so i did not have this on the radar. i also learned much about arduinos with that issue. i guess thats a huge thanks for steering me into the right direction.

    RE: Trouble with nodes going offline after a whileposted in Troubleshooting
hey. i was having the same problems from time to time - i found out that its mostly wiring - therefor i am a great fan of easypcb and other boards that let one mount the radio directly.
and also mounting a fan on my gateway (rpi3b) helped a lot with that. other than that repeaternodes...also install myscontroller - makes debugging way nicer and more efficient because you see in realtime whats going on... you might not have just one problem but more at the same time.

    RE: [solved] I_REBOOT crashes arduino while I_PRESENT does work as expected?posted in Troubleshooting
as soon as i burned a new bootloader it worked. watchdog does not like old bootloader and since mysensors is using that for rebooting it fixed my issue.

    RE: mysbootloader with MY_SIGINING_SIMPLE_PASSWDposted in Troubleshooting
@mfalkvidd said in mysbootloader with MY_SIGINING_SIMPLE_PASSWD:
@zen85 MySensors is open source. Anything is possible, if someone builds it

i am thinking about digging into this since this is the only thing missing i would love seeing. i really want the network secured with a password to be safe. i guess the main limitation is the size of the bootloader and therefor it has to be extremly clever... am i right?
or are there other options i am not thinking about to make my network a bit secure?
