Cumulus Support

Posted: **Sun 06 Sep 2009 4:04 pm**

Hello,

Since I've bought and installed my WS-4100 (WH1080 / Fine Offset) weather station the temperature readings are mostly not so perfect as I hoped they were. Is this an known issue of this weather station and do you also have this "ups and downs" in temperature? See the attachment. My minimum and maximum temperature are most of the time not correct because of these strange peaks.

Maybe I can do something to solve this? When I installed it I used new batteries so that can't be the problem because it was there from the beginning. Some days the temperature readings are perfect (second attachment).

I'm not really sure what the cause is (interference?) but you could try the setting that tries to remove the glitches: With Cumulus stopped, in the [Station] section of the cumulus.ini file, add a line: EWTempDiff=x.y where x.y is the maximum temperature difference allowed between readings.

Thanks Steve. I've done that and is much better now! But now sometimes the max temp is still x.y too high, so I'm very interested if there are more users who have this sort of strange results and how they have solved it.

Steve, today I saw that Cumulus doesn't filter all bad results:

What value are you using for EWTempDiff?

Posted: **Thu 10 Sep 2009 9:15 pm**

EWTempDiff=0.4

Posted: **Thu 10 Sep 2009 9:22 pm**

I think that, because you use commas for decimals, you need to specify that as 0,4 - sorry

Thanks, I will try it and let you know.

I suspect that what is happening is that the reading isn't suddenly jumping from one value to the next, it's moving gradually over a few minutes. In the data you've shown, it changes from 14.9 to 17.0 over a period of five minutes. Readings are every 48 seconds, so five minutes is either six or seven readings. If it's seven readings, and it changes by 0.3 each reading, that's the 2.1 difference you're seeing and is under your 0.4 setting.

We can prove this, if you want, by turning on the debug log, which will show every data reading. It looks to me as though you have a (faulty?) temperature sensor which just wanders up and down a few degrees from time to time.

I suspect that what is happening is that the reading isn't suddenly jumping from one value to the next, it's moving gradually over a few minutes. In the data you've shown, it changes from 14.9 to 17.0 over a period of five minutes.

It's not, sometimes when I have a look at the weather station screen the temperature is 16 and jumps to 19 and 40 seconds later or so it's 16 again. So I think it's one reading.

In the copy of the the debug file above were two periods with 'high temp jumps' They are not visible in Cumulus and it is also a lot better than it was, but some of them aren't filtered by Cumulus.

My weather station saves every 5 minutes the data, but I understand that every reading of 48 sec. is saved and Cumulus selects one of them (the highest?) and saves this every fife minutes? In that case, if there are two readings of 48 sec. with to high temperature Cumulus doesn't filter?

Ok, fair enough, but I don't understand why the filtering code isn't working in that case. You did restart Cumulus?

But the period you've pasted there only covers 53 seconds, and only has two different sets of readings. Here are the readings:

17:24:16 Data: 03 37 E5 00 46 B6 00 C7 27 29 4B 00 00 18 05 00
17:24:26 Data: 03 37 E5 00 46 B6 00 C7 27 29 4B 00 00 18 05 00
17:24:36 Data: 03 37 E5 00 46 B6 00 C7 27 29 4B 00 00 18 05 00
17:24:46 Data: 03 37 E5 00 46 B6 00 C7 27 29 4B 00 00 18 05 00
17:24:56 Data: 03 36 E4 00 46 B5 00 C8 27 36 55 00 00 18 05 00

Cumulus reads the data every 10 seconds, but as you know, the station only updates every 48 seconds. I've highlighted the temperature. It starts at 00B6 = 18.2C, and then goes to 00B5 = 18.1C. So there are no obvious problems there.

Cumulus just saves a snapshot of the current temperature in the log files, not the highest since the last log entry. The way the 'EWTempDiff' code works is that it checks each 10 second reading with the previous one, and if the difference is higher than the value you specify, it completely ignores that reading.

Yes, I start Cumulus mostly one or two times a day and load in all data. It's not running 24 hours.

Ah, okay. I started 'debug mode' and loaded data of the last 2 hours with two 'high temp jumps'. But now, I see, only data after the data load of two hours is saved in the file.

The equivalent data loaded at startup is logged to the diags file. But this has suggested to me what the problem may be. The 'EWTempDiff' check only applies to the 'live' data, not to the data from the logger. The logger data is at least 5 minutes apart, so it wouldn't make sense to apply the same check with the same value. It could quite easily rise or fall a few degrees in 5 minutes. Are the jumps you are seeing happening with data from the logger or with live data?

I do not know sure, but most of the jumps are in early morning or late night and then I've Cumulus turned off and since I've set 'EWTempDiff' the jumps on moments when I've turned Cumulus mostly on are less than before.
