Re: Weather Station Recommendations

Hi Andy, Need the usual measurements including UV .... What for? The Davis sensor alone for that costs (much) more than your total budget. As Ray says, there really isn't anything much at your price point. So take a look at the Weatherduino Project which now includes UV and even Air Quality Monitori...

Re: The maplin wireless wether station radio link fault

Hi Dave, Welcome to the forum. Sorry we didn't respond yo your previous post but there really isn't much to add to the answers there or elsewhere on the forum. But to summarise; you must power-down the Console (remove and replace the batteries and USB cable) to resynchronise the transmitter after re...

Re: Ambient WS-2080 RF Reset?

Hi, 433 MHz is the primary ISM "License Exempt" frequency in Europe (and much of the World) but barely "LegaL" in USA. The "official" frequency is 915 MHz, but it appears that Fine Offset may (still) use a different Wireless Protocol (FSK) for that frequency. The Fine O...

Re: Ambient WS-2080 RF Reset?

Hi Bob, I've not dismantled my 2080 (yet) but you may get some "clues" about the general method of construction from the two "...insides if..." sticky threads in the Fine Offset section. The transmitter uses a tuned loop antenna printed on its PCB, but the Console antenna is prob...

Re: Rain calculator for WS-2080

Hi, Yes the nominal rain tip is 0.3mm and the High byte is immediately before the Low byte. It's easy to make the Rain Counter overflow, just plug the anemometer into the Rain socket of the Transmitter. ;) Kevin Sangeelee wrote some code for the Raspberry Pi (on their forum and this one) but the Bas...

Re: Rain calculator for WS-2080

Hi, We have an external temperature range of more than 25.6 degrees here in the UK. ;) Also note that the Rain counter is 16 bits, the Wind direction byte includes flags for Low Battery and "Bad Direction", and there's an 8 bit CRC at the end of the message. Do you know which model of a ba...

Re: Rain calculator for WS-2080

Hi, Did you know how they represent the temperature. it has 2-byte value Welcome to the forum. I believe the temperature is coded in pure binary, in tenths of a degree above -50 degrees C (eg. 0x01 0xF4 for 0 degrees C). Only the low nibble of the upper byte is used for temperature; I thought the up...

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...

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...
