Very strange rainfall figures

Post by daveh » Sat 21 Jul 2018 4:06 pm

I have just noticed a very strange problem with the rainfall figures on my install of MX. I've never seen it before in all the time I've been running it.
I've attached some screen shots to show the problem.
Looking at the logs screen I see that rainfall for yesterday was 10.9 mm. Seems reasonable.
The today and yesterday page also shows 10.9 mm yesterday.
The records screen however shows a record rainfall of 7183.4 mm yesterday and the rainfall chart has a very strange rainfall scale on the right hand side.

Any ideas why this would happen and how to correct it please?

Looks like your rainfall counter increased suddenly, and then perhaps returned to normal. Cumulus tries to filter out such aberrances, but it depends on exactly what happened.

There's information in the FAQ and wiki about correcting rainfall, which also applies to MX, except that MX doesn't have most of the built in editors that Cumulus 1 has. So you need to stop MX and edit the alltime.ini file to reinstate the previous record (which you can get from alltimelog.txt).
