Cumulus Support

Hello Steve & Forum,

I am pleased to say that the replacement for the Watson W8681 arrived yesterday and the new La Crosse WS2300 is now in service.

Setup was a breeze and build quality in my opinion was much improved. Much studier fixtures, fittings and sensors which make me wish it had been replaced sooner.

Quick run through of the setup....

Mains Powered with batteries installed in Console & Transmitter (incase of power failure), Connection between transmitter and console is cabelled which brings the interval to every 8 seconds. Connected to a Real Serial Port via standard RJ11 to Serial connection cable (Included).

Bearing in mind I used a Watson / Fine Offset Station before, I have since changed the settings to what I hope are the optimal settings.

A second, third or fourth opinion would be much appreciated

Yep, that's pretty much how my 2355 is set up.

Great - Does anyone know the value in mm per tip?

0.518 mm.

Thanks Steve

I trust all my settings from what you can see are correct?

Looks OK to me.

Hi all I'm a newbie on here, old wx and pc nerd.

Just on an optimal settings for WS2300 series topic, what spike filtering settings are people using for this family of stations?

At the moment I'm using 15°C spike removal for temperature and it works fine, the only problem is the dew point which is not filtered, probably because cumulus get it from the station so it would be nice to apply the temperature spike removal setting to the dew point too...

You could turn on the option to have Cumulus calculate the dew point, then the temperature spike removal would apply to that too.

Ok, what is the difference between the dew point calculated from the station or from cumulus? Are there known differences between the two conversions?

I have no way of knowing; I don't own a La Crosse station, and I don't know what formula they use. Cumulus uses the same formula as Davis weather stations; I can give you the formula if you wish.

No problem steve, I trust you

Thanks for that guys, with the spike happening I switched Cumulus over to calculate the DP, if its off Davis stations thats awesome then, I also trust you Steve.

FTDI new drivers for the converter came out and everything with spike removal on seems sweet, maybe I'll remove spike filtering in the next few days and see what it does, my temp scope is similar to your's Vathek unreal

I mean it doesn't matter if the calculation of DP is a good quality one IE Davis but its just an observation of what happened.

Cheers
Stephen
