Re: wh1080 clas olhson

Hi, am I right in thinking that to get the 'green light' console working I need a 'Watson 8681-HHT Pass 14' transmitter?. AFAIK no, not if the Green Light Console has a "grey" surround. That appears to be the old "Pass 7" protocol, but your photo shows a "Pass 14" trans...

Re: wh1080 clas olhson

Hi, Yes, Clas Ohlson appear to have been one of the last suppliers to change to the "new" wireless protocol, I think at the same time as the blue backlight was introduced. Note that although it is quite "easy" to receive and decode the "new" OOK protocol (e.g. with a Ra...

Re: Raspberry PI link to weather station using the supplied transmitter?

Hi,

Ah yes, I thought I'd answered that question.

One of the hazards of an OP asking the same question in more than one thread. ;)

Cheers, Alan.

Re: Wind Speed Abnormality

Hi Andy, Yes your diagnosis sounds very probably correct, but a few easy things you can try first: Windspeeds are generally lower at night so the new anemometer might just be "stiff". Is it definitely rotating at night when no wind is recorded? I presume the slightly elevated zero line on ...

Re: Raspberry PI and Maplin N96GY stopped working

Hi, ....has anyone managed to receive the signal directly from the weather station onto a Raspberry PI so as to by pass the receiver/display? Yes, do a search on this forum and elsewhere for Kevin Sangeelee, for example here . The "Maplin" station is a WH1081 in one of its numerous "f...

Re: MAplin W1081 Fail need advice on replacement

Hi, AFAIK the WH-1081 is still being manufactured and is available with various "badge" names. The most obvious is the very similar WH-1080 from Clas Ohlson which adds a Radio Controlled Clock [EDIT: might have been removed], 868MHz radio link and a blue backlight, but all of those feature...

Re: Intermittent wind speed in Fine Offset WH1080

Hi, Yes, anemometer (speed) on the two middle pins (or Rain on the other connector) and Direction (vane) on the two "Outer" pins (of 4 in RJ11). Polarity not critical (the sensor circuit is effectively symmetrical). Contacts 1 and 6 (of RJ12, if used) are not connected. Interestingly, the ...

Re: Sunshine hours

If UV index is above 0 then count that the Sun is shining? That's very unlikely to give a useful value. In summer, the UV Index can be well above zero, even under cloudy skies (and resolved only as an integer). Estimation of "The Sun is Shining" can be quite difficult (particularly betwee...

Re: WH2080 hangs up and memory lockup

Hi, Welcome to the forum. You might find more information in the Fine Offset section of the forum. Maybe you have a (new) local Radio Frequency Interference problem, or maybe the station (Console or more usually the Transmitter) has become faulty (not that uncommon with these low cost stations). I'm...

Re: Intermittent wind speed in Fine Offset WH1080

Hi, Yes you can probably assemble the connectors in a bench vice or with a simple "Punch Down" tool, but you can get a proper crimp tool from ebay for about £4. You might even find a seller that will bundle ten RJ11 or RJ12 (6p6c) with the crimper at a modest cost (but normally they will b...

Re: Intermittent wind speed in Fine Offset WH1080

Hi, I didn't respond to this particular thread because most had already been said before. Just to clarify, as a test you can plug the short anemometer cable directly into the Rain socket and rotate it a few times. But note that it may take up to 48 seconds before the reported "Rain" sudden...

Re: WH3081 has stopped receiving readings, but UV & solar still work

Hi, AU$34 is probably broadly consistent with the price from a retail seller, i.e. one offering full support and some guarantee that it will meet your requirements. The rather simpler WH1081 transmitter is sold by our "Maplin" retailer for £15, shipped and with a free-return policy (but ot...

Re: WH3081 has stopped receiving readings, but UV & solar still work

Hi, Replacement "external transmitters" are certainly "available" but sometimes at a price that is too high to be worthwhile. Also, there are numerous versions which all look very similar: Firstly, the carrier frequency may be 434 MHz, 868 MHz (mainly Europe) or 915 MHz (USA) but...

Re: WH3081 has stopped receiving readings, but UV & solar still work

Hi, The "Solar Pod" has its own microcontroller which generates a separate data packet which is passed on to the radio transmitter in the main "external unit". So it's quite possible for only one of the two controllers to "crash" (or the critical message-timing to becom...

Re: Replacement for the standard rain gauge ... ???

Hi, I did experiment with adding a 14 cm diameter plastic funnel above the normal FO rain sensor with the aim of achieving 0.1mm per tip. But to be honest it was rather a failure because the rain collected in beads in the funnel (even though it had much steeper sides than the FO) and didn't give an ...
