Hi, I have a Wastson W8686 PWS which is a clone of the HP2550. I've noticed over recent weeks that my PWS would register the odd 0.3mm when there are clear skies. It happened again around lunchtime today. Sun is shining and 0.3mm is recorded. I checked the PWS Friday, cleaned out the tipping bucket (it wasn't dirty as I'd done this the week before because of these odd issues). I'm wondering whether the wind is playing a part and moving the pole it's attached too. For example we had heavy rain this morning so it's possible the bucket could have been almost at tipping point when it stopped raining and the slightest movement tipped it. Had anyone come across this issue of recording rain when there is none? TIA Dave

You're right but it's the arrows that I drew on the photo that are slightly wrong. They aren't exactly pointing North and South, more NNE and SSW but it was just to give a rough idea where south was. -

I suppose the air temperature warms up the air around the sensor when the sun is out. The old school thermometer by the back door which is in shade all the time this time of year was recording a touch over 11C at the time. -

That's a good spot. There do seem to be quite a few days that the top temp has been around 2:30pm. It's been in the same location since I set it up on the 23rd Jan. To the south of the PWS is a path and to the south of that a lawn. See pic. -

This is today: This is from the first full day I set it up (24th Jan) to today. On this one, I don't now where the 13C reading earlier this afternoon has gone. -
Placing a Weather Station

Ok that's interesting regarding the WS80 giving better radiation screening. I've put my Watson W8686 PWS in a sunny spot, the closest obstructions are to the north, however I've noticed a couple of times and especially today as it's been sunny that my temperature reading has suddenly spiked. I'm assuming the bit at the bottom is the radiation shield for the temperature sensor but it doesn't seem to be giving much protection. It sits on top of a silver pole and I'm wondering if this could be an issue. Alternatively the sun is still low in the sky so that might be the cause. -

Thanks yes I had read that with an all in one it's not possible to get the best readings for everything. I read that the wind sensor should be 33ft high. I took the decision that an accurate temperature reading was the one I was most interested in so that's 5ft above the ground in the corner of my veg patch. See photo. Regarding debris, it had crossed my mind about leaves in Autumn as we have some big trees nearby and when the Ash starts to drop its leave they get everywhere. I hadn't however considered the birds until etaf mentioned it in one of his other threads. Hence my question about a bird spike. -

That's great thanks. How do you find the temperature readings with it? Particularly in summer, does it give reliable readings even though it's in the sun? I know it has the protector on it but some I've seen are quite large, I assume to allow airflow and keep it a realistic reading. I've only had mine just over 2 weeks so haven't been through a hot spell yet. I think being on the edge of a park seems to give lower readings that those nearby on housing estates. -

That's a great idea. I would never had thought of that. Thanks for the tip on the SD card too. I haven't had the need to use one yet. -

Hi etaf, Did you manage to put some pins around your rain trap? I'm curious how you did it as I have a W8686 too and am struggling to work out how to do that. Thanks Dave -

Thanks Mandrake. It was written on the back of the console. 868M. I've just had a look on Froggit.de and there isn't a UK or GB in the country dropdown list. Not sure if this is because of Brexit. -

I bought a Watson W8686 in January 2021 and it was very easy to set up. My first PWS. It was recommended on another forum and really pleased with it. Anyone know if the WH31 for the W8686 is 915M, 868M or 433M frequency? Are there any guides as to what I need to do to update the firmware? And what are the consequences if any of not updating the firmware? -
Bresser stations any good?
Chelmer Park replied to 101_North's topic in Weather stations and equipment
Can this be easily fixed to a 2inch or 1.5inch aerial pole? Reason I ask is that I have nowhere to fix a weather station to in my garden without it being sheltered by something (Trees, next door shed etc) and my only option is to buy an aerial pole put that in the ground and hopefully fix the weather station onto it. -

Thanks. My garden backs onto a public park, I probably should've mentioned that in my OP. Thinknig about it some more last night, I might need to place it on a pole somewhere central. I just need to find a pole that will work. I'm sure some might have done this. -
Hi All, I'm new to these forums and new to weather station technology. I've been reading this thread about weather station recommendations and am looking to spend a similar amount. I do however have a question about where to place a weather station. Photos I've seen are of weather stations attached to shed roofs. I don't have a shed in my garden. I have a conservatory and a lawned area and a veggie patch. So I'm wondering what people do when choosing a location for their weather station and what can be used if there's no shed. I assume it sholud be in a position free from obstructions/shelter so it can monitor wind. rain, sun, temp etc. Thanks Dave
