Cumulus Support

A couple of weeks ago I realised that I was way down level on CumulusMX (3.8.?) so decided to upgrade.

Station is a WMR200 - everything was working fine, but thought going to the latest level would be good.

Downloaded the pi image, installed fine, copied my old dat over, worked fine for a couple of days, so then went to what was the latest (3.11.4 b3133).

Ran fine again for a couple of days, then appeared to stop getting data. Restarted Cumulus, all good again.

Ran fine for another 2-3 days, stopped again. Restarted Cumulus, enables logging.

Ran fine, stopped just after 02:00 this morning.

Any ideas??

It looks like some sort of issue with the stations connectivity. Can you do things like change the cables?

Also switch on debug and data logging and see if that provides any additional information (I don't really hold out much hope though).

Thanks Mark,

I've since looked at syslog and noticed I was getting low voltage warnings.

I've replaced the PSU and USB cable and they have gone away.

I'll see if the 'Index' error comes back.

Logging is enabled.

Mick

After months of zero problems, this has come back again!

It happens 3-4 times a week, no pattern, various times of day and night.

A restart of cumulus fixes it until the next time!

Currently on 3.13.3 b3148 (I know b3149 is out).

I have made zero changes to the station, cables, Pi, PSU.

Checked SYSLOG, no low voltage warnings that I can see.

Any ideas? Any more logs I can take?

Station is WMR200.

How the WMR data is read is a bit unfamiliar to me, it is hard to tell from that snippet but it looks like the station starts sending 1 byte packets (the length is the first byte printed) which generally seem to mean that the station is saying history data is now available. However the decode appears to be going awry.

The WR200 only starts recording history data if a program is not connected, so was MX disconnected before these events?

No disconnect, the WMR console and Pi and permanently connected and share the same power feed - nothing else on the short extension lead from the wall socket.

Any other logs that would be useful???

Not really, your console either stops sending data altogether, or appears to disconnect for while then starts sending historic data packets to catch-up the missed data which CMX will not process unless it is restarted. At the moment it looks like an issue either with the physical connection, USB ports sleeping, or a sick console.

Still getting this intermittently, no apparent pattern to it.

I have changed:

- Raspberry PSU and cable
- USB cable from WMR200 to Pi
- New batteries in the WMR200

Doing a restart of Cumulus sorts it out until next time.

I have set an alarm so I get a mail when this happens (stopped sending data), is there any way I can trigger off this to restart Cumulus without needing to SSH to the Pi??

Strange - the new batteries in the WMR console has lengthened the time between 'hits'.

I have also been playing with a script that runs every 15 mins (via Cron) and checks the log for errors. If found, it restarts Cumulus.

So far, so good.

Not currently, the restart option was not ported across from Cumulus 1, I suspect partly because it is harder to do cross platform. It is further complicated now by CMX being able to run as a service or interactively cross platform.
