Wind sensors finally up on the roof

It's only taken nearly four years, but I finally have my wind sensors up above my roof line

Shame there's no wind

Ah, too late, the light is going, it will have to be when I get back home on Friday now. Stupid, I should have taken one!

Enough wind to see Climatica working though. What interval is set currently - looks quite short - 3 secs?

It is doing 5 second downloads, but the web server is testing the batch download process and 'inventing' an additional value to 'simulate' a value every 2.5 seconds. If you look closely at the top right corner of the window you should see a tiny status indicator, green = downloaded OK, grey = waiting, red= download failed.

Ah yes, sorry, I remember now. Been too busy I'm afraid the past few weeks. But still seems to be working well. That low on the models for Dec 5th might give it a good test (if it ever happens in reality of course).
Edit: I see you're also looking to test the top end of the pressure dial!

OK, here is a photo of the installation...

(and I know the soil pipes don't comply with regulations, but they have been like that since the 70's!)
The wind speeds seem to be correlating with Ray's in Cheadle Hulme (a few miles away) quite well...

That's a good job done there Mark.

Looks to be at the optimum 33ft.

It won't be far off Ray, but there are some pretty big trees dotted around here, and next doors roof is higher than mine, my pole does bring it above their ridge line, but not by a great amount. Luckily their ridge line aligns with mine, so it shouldn't cause a huge amount of turbulence. Now I need a sunny day around noon, or a clear sky at night - neither of which seem likely at the moment

- to double check my North alignment which I did by compass when it went up.

Yes, I remember the trees especially that large one to the south of you. I just used Google Maps to get mine aligned and it seems close enough.
I thought you might want clear skies for Comet Ison. Not the spectacle we hoped for but if it's clear next week I'll search for it. You'll have a better chance with your darker skies.

Very impressive, Mark.................... if I get around to upgrading my station, as I hope to, I'll have to make more of an effort positioning my wind sensor.

Well amazingly it was clear today, so I checked the alignment at local noon, it is spot on as far as I can see, well within a few degrees anyway.
I will be having a look for ISON though it is looking like it will be a bit dimmer than hoped for
Geoff, no regrets from me for going with the VP2, though I have had to invest some time in it as I skimped on the money to buy a less than perfect one. Even the 6332 transmitter was a second hand bargain that I waited 6 months for one to appear at the right price. Still tinkering with things and adapting them is half the fun for me.
Next task is to relocate the ISS/rain bucket and maybe get the solar/uv sensors up on the opposite gable end with the help of some long cables. That big eucalyptus tree to the south of me a couple of houses away shades the solar sensors in the middle of the day during the winter despite them being at the top of a pole. Or... anybody got any copper 'slugs' for an air gun
