Re: Additional temperature sensor

Hi, It might depend which of the many models that Fine Offset manufacture(d), that you're considering. But if you mean the "classic" WH1080, etc. then very probably not. With it's generic USB interface, you can't even run two separate Consoles (with different external sensors and maybe radio frequen...

Re: Lightning sensor

Hi, It is a feature of some of the ECOWITT weather stations (previously known as Fine Offset), for example I noticed it in the following advert (but they are not as easy to buy in Europe). Also beware that the specific reference to "lightning" might be a "mis-print" because that list does not includ...

Re: Using Data from Solar Panels

Hi, Note that Davis actually fit a spirit level (bubble) to their Solar Sensors, so that they can be set exactly horizontal. Also, one of the reasons that Caneira (Werk) used a small PV panel (only some tens of square cms) in preference to a traditional photo diode or transistor, in his Weatherduino...

Re: n96gy temperature sensor

Hi, Yes, it's probably a thermistor in the External transmitter. I did actually characterise one some years ago, but the data is on a different computer that may take some time to find. I think it might have been 20k ohms at 25 degrees C, which is not particularly common. If you can find a thermisto...

Re: A mysterious lapse into constant zero readings on temperature

Hi, Do you mean zero degrees (0 deg.C) or "no reading" ("---") ? The "old" versions of the WH-1080 use a thermistor in their external transmitter, read by an ADC "shared" with the Wind VANE. If there is any "leakage" (water or maybe worse) between the Vane core and the Anemometer Ground core in the ...

Re: Ecowitt GW-1000 suggestion - added b3067

Hi, IMHO some data is basically "garbage" and should carry a "health warning" (in this case almost literally) before being posted to the internet (or anywhere). It's unfortunate because the Davis solar sensors (and documentation) are highly professional, albeit at a rather high price. I don't have a...

Re: Watson W-8691

Hi, The rain and wind is transmitting fine. It's the temp and pressure that are not. Presumably you mean Humidity, the pressure sensor is in the Console. The causes of your problems may depend on the age of the station - not all Fine Offset stations are the same! You might find more information in t...

Re: Cumulus High Wind won't read over 50kmh

Hi, Welcome to the forum. What does the Console (LCD display) indicate for the maximum wind speed? Similarly, what about the normal (supplied) "Easyweather (plus)" software? You can download logged data to both applications, but they cannot be run at the same time. Is the maximum exactly 50 km/hr? I...

Re: Help Please Trying to set up maplin N25fr for Primary School

Hi, It looks as if the N25FR was the real "bottom of the range" station (even for Maplin) without a Wind Vane or computer interface, so you won't find much interest here on the Cumulus forum. It might be relevant whether yours is a "Primary" school (as in the OP title) or is more advanced. The best ...

Re: Can Cumulus software be used to calibrate hygrometer of WS-1080?

Hi, I've gone ahead and ordered a new temp/humidity sensor for my WS-1080. From where have you ordered that? It's a regular question on this forum and nobody (else) seems to have known the manufacturer or type number of any of the several types of T/H sensor fitted to the various FO stations. Cheers...

Re: Fine Offset 1080 suddenly more frequent lockups

Hi, Strange the UV info still comes thru. The UV (and Solar Lux) data is encoded in the "Solar Pod" and sent as a separate data packet directly to the "transmitter" section of the "External Unit" (via the 6-way cable into the "rain" socket). So obviously the radio transmitter itself is still functio...

Re: Fine Offset 1080 suddenly more frequent lockups

Hi, A couple of real "long shots", but I've also been having (different) problems with one of my trusty 1080s. Could there be a "2020 bug" in the software, or might the EEPROM simply have "worn out" (my issue started with some garbage data in the logging) ? I did notice that the lockups became more ...

Hi,

Your profile (still) shows your Operating System as Windows XP. AFAIK Cumulus MX (still) can't run under XP?

Re: No reception when it rains - OK when it's sunny

Hi, Energizer Lithiums deliver almost 2 volts (each) at light load, so the voltage shouldn't be an issue (unless it's too high! ). Do you have any "obstructions" between the transmitter and receiver(s)? Damp brick for example may reduce the signal quite considerably, particularly if 868 MHz rather t...

Re: Does anyone use wind measurement correction?

Hi, Wind speed similarly lower on Davis [17.1 km/h] than on Fine Offset [21.2 km/h] - ratio is 1.24 So, having considered all this, should I add a correction factor of +20% to the Davis wind speeds? Thanks for those interesting observations which appear to confirm that the OP shoould NOT introduce a...
