Move to new server

Hi Guys,

My weewx v3.5 has been running perfect for about 5 years on my odroid u3.

Until the other day it stopped, I rebooted and found various messages in the logs suggesting filesystem corruption.

Anyway, it seems to be going again (for now)

http://rollestonpark.myzen.co.uk

But thought I'd try and move to new hardware.

I have been testing a network booted Raspberry Pi4 with no sd card. (maybe will run better without SD card etc)

This seems to run well.

So next is to install weewx on it.

I know I'm running an old version, but can I just copy over my v3.5 weewx from my odroid and enable the systemd service?

Or will this not work?

It's just I have various custom stuff I did years ago, and can't remeber how I did it.

I probably should upgrade, but it has been running so nicely, I thought I'd just stick with it as it is.

Thanks

Chris

You will have to install the prerequisites on your new machine but, other than that, a simple copy of the weewx files will work. If you installed using the setup.py method, just copy over the /home/weewx tree.

OK,

thought it was all OK, but I get this error when I run weewx manually:

This is a bug that was fixed in V3.6.0. See issue #111 for the fix.

Don't know why the bug didn't affect you with v3.5.

I bet the prerequisites are a different version than on the older system.

Just realised, did some googling, testing now.....

I think maybe it's to do with the newer python librarys I would have installed when setting up the pi

Cheers

The WeeWX prerequisites haven't changed in 10 years. It's possible that newer versions of PIL are more sensitive, but PIL hasn't changed much either.

Don't know.

Seems all good now after those few hicups.

Will see how it holds up running on a pxe booted Pi4

Thanks again for the great software

I've been running the WeatherFlow UDP driver weewx on a pi4 for 5 months now.

Works great.

Sorry guys slight issue with my bootstrap skin:

http://rollestonpark.myzen.co.uk/Bootstrap/

The font on the dials and graphs is tiny.

I must be missing some sort of font from my raspbian install (maybe?)

Any ideas, not sure what to check on this one.

Thanks

Chris
