I am running CumulusMX on a Pi without problems and I never reboot.phipps wrote: I do have a couple questions, what's the reasoning behind doing a reboot every night?

sudo crontab -eCode: Select all
sudo halt
I agree, an occasional reboot is a good thing. What command in crontab would I use to do a reboot once a week, say Sunday morning? Can you set up a reboot every other day? Does that require a seperate line in crontab for each reboot?ExperiMentor wrote: Daily reboot is not particularly needed. It's just generally a good idea on any computer running anything continuously, a good habit. It just ensures that any over-filling buffers get flushed, etc. And if something had gone wrong with Cumulus MX or any other running program (I run other things too on the same Pi), everything gets neatly restarted, so that problems get a chance to fix themselves eg if you are away on holiday.
From the Cumulus MX wiki https://cumuluswiki.wxforum.net/a/Cumulus_MX_FAQSerial device names on Linux are not COM0 etc as in Windows. You need to specify something like /dev/ttyUSB0 - do a dmesg at a command line prompt and look for the actual device name from your adapter. If dmesg says your cp210x converter (as on Davis stations) is attached to ttyUSB0, for example, you need to put /dev/ttyUSB0 for the serial port name in MX. You can set the serial port name in the MX user interface, but if for some reason you want to do it by editing Cumulus.ini, note that the item in MX is called ComportName (which is a string, for the full device name, e.g. COM1 or /dev/ttyUSB0) rather than 'Port' which is just an integer. If you have not run MX yet, this item will not exist, so you will need to add it (in the [Station] section).
Thanks a lot! I can now connect to my weather station.water01 wrote: ↑Sat 01 Dec 2018 9:36 pmFrom the Cumulus MX wiki https://cumuluswiki.wxforum.net/a/Cumulus_MX_FAQ
) I will report back.
I'm using an old Maplin kit on a brand new Pi 3+ and my COM port is /dev/hidraw0 though - found this through dmesg:
