Re: Data flatlining

Hi, "0.3 degrees rise in 48 seconds" might sound like a reasonable limit, but it isn't. Firstly, several "messages" from the transmitter might be "lost" due to radio noise or interference of some type. The Console only assumes a "problem" if about 7 consecutiv...

Re: Data flatlining

Hi, Slightly different problem but possible the same cause. I get just the outside temperature flat-lining at around 7am each day. It was intermittent but is turning into very regular now. Strange thing is that it is only the Outside Temperature that flat-lines. You have checked the spike removal se...

Re: Recommended wire to use

Hi, Welcome to the forum. Are your sensors Analogue or Digital (e.g. I2C data bus) ? 10 metres it getting rather long for I2C (but possible). If analogue, what are the typical signal amplitudes and source impedance? How many cores do you need in each cable run (signal, power lines, earth, etc.)? The...

Re: N96FY Transmitter Cover.

Hi, Yes, I believe the WH-3083 cover will fit fine. But I think it has a hole in the top for the cable to pass through to the solar Pod? Not really a problem, I found a water bottle plastic cap that fitted perfectly, but there must be plenty of other solutions. That said, the performance of all thos...

Re: Vantage Vue Is Goosed! Probably.

Hi, I don't know anything about the construction of the Vue, but I believe the wind speed sensor is a simple magnetic reed switch (inside the "cartridge" ? ). As an intrinsically mechanical switch, it's possible that after 7 years in Orkney wind speeds it's simply "worn out". If ...

Re: Fine Offset temperature sensor glitch

Hi, Yes I do vaguely recall somebody (also in Australasia) reporting a similar defect with two WH-3083 stations, perhaps a year ago. I do remember contributing to the thread, but that doesn't help me find it again now. :( The "old" Fine Offset stations used (analogue) thermistors to measur...

Re: Cumulus receiving wind data problem

Hi, That does seem to be an "unusual" error; you could examine the Oct17log.txt file to see if there are any clues. Also, if the data is still stored in the Console, you could copy the backup files from a previous time/day (into the data folder) and try downloading the data from the Consol...

Re: Problem: Aercus WS3083 station and MX ....

Hi, It sounds like the classic "USB Lockup" issue with the (more recent) Fine Offset stations. A quick forum search found around 50 threads on the topic; basically you probably need to set the "Synchronise Fine Offset Reads" option. But here is a thread with an answer from the ho...

Re: Jacking plugs for Davis Vantage pro and similar

Hi Rob, There should be plenty of offers on ebay, or I often start with CPC (Farnell) if I'm going to spend £6+ on components (free shipping). Sometimes "Kenable" are good for these small items (they also have a presence on ebay) , but the first link that a Google found for me is: https://...

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...
