Rain rate not registering

Post by Grahampp1972 »

Hi all. I'm using an Aercus Instruments WS3083 station. The rain is registering ok and totals are building up, but cumulus doesn't seem to be registering a rain rate at all... It still shows a high rain rate of 0mm/hr for the day.

I've never had this problem before and am wondering if anyone knows a fix?

TIA, Graham.

Hmm, I had a look in the code, going right back to what Steve released in 2018, and I cannot see where the rain rate is calculated for FineOffset stations!

I can see it gets calculated when reading the historic data, but unless I'm missing something obvious I cannot see anything for calculating the rain rate from the live data. :?

Found it!
So the rain rate is calculated over a 5 minute time span. If your rain tips were longer than 5 minutes apart, then you would not register a rain rate.
