Re: Pressure Graph Wonky

Hi, There's quite an art to reading graphs, particularly if they are "auto-scaling" as here. You need to look at the actual figures along the vertical axis. Also, using a longer horizontal axis (time) will tend to include a wider range of data and reduce the "sensitivity" of the ...

Re: CMX on an x86 tablet?

Hi, I have a USB to Micro USB adapter to connect my station to it I think the software will probably work, but how are you going to power the tablet? They normally have only one micro USB socket which can act as a USB host (with moderate power output for something like a mouse) but the same connecto...

Re: Pressure Graph Wonky

Hi, You appear to have just one "rogue" zero in the data file at about 2.30 pm. Correct that (in the September file) using a text editor or the built-in Editor and you might find that the remaining data is not "flat" (just swamped by the autoscaling). Pressure is measured (only) ...

Re: Data Connection for Fine Offset

Hi Mike, 3 years old should be the "latest" protocol/software, but obviously still worth checking for compatibility. I have found one thread which looks quite encouraging. The N96GY referred to in the fourth post is our "local" version (Maplin) of the 1081. The extenders seem to ...

Re: Data Connection for Fine Offset

Hi Mike, Extending the USB connection (with CAT5 converters) has been discussed a few times on the forum, but I don't recall anybody specifically reporting either success or failure. There is also available the fully functional Display unit from my old F.O. Weather station, which could be used, if n...

Re: "Record data" not matching real data

Hi, Maybe you have a (new) source of radio interference, although 868 MHz is generally better than the much-used 434 MHz radio band. The transmitter does use a CRC validation code, but it's not 100% reliable. Also, can you check the Transmitter batteries? The "Rechargeable Alkaline" type c...

Re: "Record data" not matching real data

Hi, That looks exactly like the standard "Fine Offset" (manufacturer) WH-1080 which are well-known to produce occasional "spikes" in the data that they transmit/receive. They are the main reason for the "spike removal" settings in Cumulus > Configuration > Calibration s...

Re: "Record data" not matching real data

Hi, the rain data must be somewhere in the station and it is definitly not. There must be "rain data" stored inside, or supplied by, the "station", in some form . But we have no idea what that is because your profile describes the station as " No Name " and you haven't ...

Re: Photos of the insides of Fine Offset sensors.

Hi, You'll need a lot more data than that! The string(s) of zeros are probably the rain counter (at least two bytes) and the Wind Gust and Average (1 byte each). So try a sequence of Rain Tips and (separately) spinning the anemometer. Those 80s before the 00s might indicate that all the data is disp...

Re: Davis VP2 Relay Device

Hi, <pedantMode>Taking refraction into account Is it actually refraction, or mainly due to the "complexities" of the 3D geometry? I believe the (atmospheric) refraction is around 0.6 degree, which I wouldn't have thought could account for more than a few minutes of day length. But I realis...

Re: Davis VP2 Relay Device

Hi, For Latitude 38 degrees, the maximum day length appears to be 14.75 hours or about 220 degrees (i.e. from 70 to 290 degrees azimuth). So it looks as if you should be alright, but may need to also consider the diameter of the mast and sensor, and possibly reflections from the mast. BTW a maximum ...

Re: AERCUS WS3083 weather station ...

Hi, I have built my own crude solar power device based on a simple PV cell and calculating the power delivered into a small load resistor - crude but seemingly effective. It's the "short-circuit" current that you need to measure, not easy with a single photodiode. However, you can use a sm...

Re: AERCUS WS3083 weather station ...

Hi, That sounds like the well-known "USB Lockup" issue with all of the "recent" Fine offset 108x and 308x stations. Nothing to do with the transmitter but the Console firmware. Have you selected the "Synchronise Fine Offset reads" option in the Cumulus Configuration > S...
