I think that depends on the sensor.
With the Davis wind sensors I find the opposite. Because the cups are free to spin with only the bearings resistance. The vane has to drag a potentiometer around and requires a higher wind speed.
My old FineOffset that used reed switches for 16 directions and had a freely rotating direction vane was ridiculously sensitive and wagged around all over the place if you just breathed near it (slight exaggeration!).
Curiouser and curiouser. . .
Your PWS definitely showed 360° yesterday, I even listed the contents of your clientraw to check (no mean feat as it changes so often). But my clientraw never contains 360. . . the anemo only has 16 sectors and N is in sector 0.
I’ll try to get a snip next time 
EDIT: see attached Bashy.png 
I only see 0° when WD can’t keep up and all the boxes are zero (like your example) and/or block is Offline - see Bashy2.png.
IIRC a Davis anemo has a gap in the pot so it can’t actually measure anything between 356-004. I wonder if it reports something different for N when moving clockwise or anticlockwise 
You’re probably right. With the vagaries of the wind though you can’t be sure that a wind that moves the vane would move the cups. I’m just watching the very light breeze in the garden. Some leaves are moving but other leaves just a few inches away are perfectly still.
I also don’t know how Davis report showed. Minimum reported speed is 1mph but do they round up, e.g. 0.5mph is reported as 1mph or does it need to really get above 1mph before it reports it. So the cups and vane could be moving with zero mph reported
My WD points to north randomly, i see this reciprocated on the websites, this will be the north you see randomly. Its not WD keeping up, there is some conflict somwhere thats causing it since i added WLL, it never did it with the Envoy.
Whether its the vane or my spinner not 100% free, either way, i still see the vane on occasion when its calm, move and the spinner stays still, if it is slightly sticking its certainly ever so slight. You can see the vane move in the image i posted above and no speed was recorded, yet later on the vane move even less but speed was recorded at that time.
So with that in mind, back to the point, if it is calm, i would prefer to see the stated direction than to see 360º or 0º so i know the last know direction. If thats not possible, then i would prefer it to say calm and have a visual with the dir arrows.
As an FYI, when i had that dead calm this morning as seen in the image, twas quite a decent period, enough time for the average to drop off, during this time, my Davis console and my OS 968 console both stated the last know dir bearing and arrow. This is what im used to so i spose its down to each individual and what youre used to.
No speed recorded doesn’t definitely mean zero mph. Depending on the way Davis do it there could be 0.49 or 0.99 mph of wind and it would still read zero. That may be sufficient to move the vane whilst recording no wind speed. Also as I mentioned earlier, I was watching the trees in the garden earlier. With a very light breeze (approx 1mph) some leaves/twigs moved a bit but other similar leaves/twigs 6-12 inches away were perfectly still. So the vane could move when the cups didn’t.
That could be eddie’s perhaps?
As it was this month morning, at 10m there was no movement from the cups, the WS80 at 7ft recorded a consistent speed of 0.2 and gusts around 1.6 to around 2.2mph
Its quite low speeds at present, i was just watching the Davis stop dead and th WS80 still recording around 1.34 i think it was to about 2. sommat, forgot now, davis still stopped then looked up at the davis again and it was at 4mph, not as low as this morning so i cant check the vane against the speed this time… But i was just looking out the window at it now and the speed was going round probably about maybe 5 second a turn and showing 1mph, then it stopped like it hit a brick wall, that tells me it mihgt be a little sticky or the wind just dropped, i think the former…
Just been anny watching again with the console in front of me, each time the speed stopped the vane would still move 1 degree at a time on the console from 296 to 299 then the cups started up again at 4mph
Getting back to the subject of this thread. . . no, I can’t work out how to get SSGauges to show 360° for N if %dirdeg% shows 0 
Just noticed that the book referenced in Reply #2 above says VP2 anemo cups don’t start to move until wind is 1.4 kts, while wind vane doesn’t start moving until 2 kts (author’s tests).
But once they are moving I presume they can record lower speeds?
With that in mind then, if it takes 2kts to move the vane then it’s safe to say that the cups should be spinning as they take lower speeds to move. This tells me that my cups are not as free as they should be so a new cartridge is needed.
I also want to point out that when you’d see my PWS site data go offline, that’s an issue that I have caused when modding the code this not wd being able to keep up, I know this because each time it happens, refreshing the page starts it up again straight away. I’m not fussed about it, it’s sommat I caused but the page looks how I like it
I find my vp2 cups rotate with the slightest breath of air, not noticeable to me. That sensor was installed in July 2019 after the very old got sticky.
The vane does require a bit more to move it.
Just reporting what I read. . . seemed strange to me, too. Book was published in 2012, maybe recent design differences?
Thats how i find mine to be…
…I cannot remember when i installed my replacement cups, but I think it might have been 2017, I bought the VP2 in 2016 and if i remember right, the new cups were a warranty exchange. so yeah, that has to be 2017 but cannot rule out 2016 completely. So i think they are due for renewal. Dont get me wrong, they don’t stop with any rocking to suggest a bearing fault, heck, maybe its just that it needs a clean as it does suffer from cobwebs during the warmer months, perhaps my brush on a 10m poles didn’t quite clean it as well as it should lol. I will get new ones though as i am not pulling the mast down to clean it then put it back up only to find its got to come down again
