Pi Zero

Simple question.

Will Cumulus MX run on a Pi Zero?

Thanks,
Richard

Simple answer "Yes" . Try the image install, it makes it much easier.

Simple answer - Yes.

Caveat, the zero has a single, slow CPU, so things run slowly on it. CMX operations like loading the records editors that complete in seconds on a 3B or 4 take minutes on a zero. (Assuming a few years worth of archive data is available)

And just wait until you install or update Mono - it's painful on a zero.

I do not recommend a zero, but if you do use one (I have CMX loaded on one for testing) I would not run anything else on it, and make sure you run the minimal Raspbian distro,

Thanks for the replies.

I had Cumulus 1 running on the Zero (quite happily, on it's own).

I've subsequently done a fresh install of MX (from the image). I can access the web dashboard successfully, and it looks to be OK, but I can't get it to update a website.

I just wondered if perhaps FTP was a step too far for the Zero.

Time for an in depth reassessment I think.

Did you somehow run a Windows emulator as Cumulus 1 is a Windows only program?

I have two weather stations (Froggitt WH65 and Davis VantageVue). Both have data logged via CMX running on separate Pi ZeroWs (the wifi one). The PiZeroWs run debian 10 with mono 5.18 and the debian 10 is the 'lite' version - i.e. no GUI or additional apps.

Yes - they aren't the quickest of devices but the do the job well and quite reliably. Nothing else is running on these and the average CPU load is around the 10-20% level.

Both provide data to a Pi 3A that provides the web service. Only one system data publicly available at present as the second system (Davis VV) is a bit temperamental at present! Both systems log data to a MariaDB running on an old Pi 3B which is booted from an SSD.

For their cost a PiZero(W) is a no-brainer for headless, virtually unattended, running of CMX.

If you want to have a more powerful device for CMX then the Pi 3A would be a very good choice. This would easily support CMX and a database server. I prefer my externally connected systems (webserver etc) to be stand-alone just in case! Over the last couple of weeks my BT SmartHub 2 detected and 'repelled' a number of DoS attacks that appear to originate from China.

Hello David,

Yes, sorry, you're quite right. It was MX, but a old version from well before the website update.

I was posting in between remote desktopping in to work from home, so I got a bit confused.

I think I'll have to leave it until the weekend so I can concentrate on one thing at a time!

Thanks again all,
Richard

Agree. If running CumulusMX and nothing else intensive, PiZeroW is the ideal hardware.
No problems with standard FTP uploads to thed usual online services.
There's no issue running some other stuff on the same machine simultaneously - eg PiHole, which also needs to run 24/7.

Running a webserver is too much.
Mark says very slow loading the records editors, but I've not had that with about 8 years of data.

It's also fine with the full GUI image - it does not use additional resources unless you actually start the GUI, so is OK for occasional use.
