Topic: Davis Vantage Vue wind issue

[Kamakzie]

Hello, I've had this weather station for going on 10 years. Recently the wind speed isn't being calculated very well. My father went up on the roof today and fixed it but it still isn't showing a wind speed at times even when the wind is obviously blowing. Would there be anything I can do to fix this other than buying a whole new weather station? Would buying new cups do any good? Maybe I'm expecting too much for such an old weather station?

You could send it in to davis to refurbish your unit.

Any guess as to how much that would cost?

Not really sure but last time I did it... Was around 100 dollars plus shipping.

You wouldn't have to replace the whole Vue ISS just the part associated with the anemometer sensors, not that hard to replace yourself.

I've never owned nor had a Vue ISS in hand, but from all I understand replacing individual parts is nothing like the VP2, whereas I can attest, everything is modular child's play.

The Vue ISS is much more modular (as such in the true sense) than the VP2 which I would class more as individual components.

Certainly possible my word usage is inexact. All I know is that the VP2 is super simple to disassemble and replace parts, I can't see that in a Vue.

Depends what the problem is:

If it's simply a stiff/seized wind speed bearing then the mechanical part can be replaced.

But if it's a circuit-related issue, eg reed switch in an old Vue going faulty then chances are that the best solution will be a complete new ISS (or a Davis refurb which is close to the same thing other than the case).

Vue stations up to Rev F (can't remember exactly what year this maps to but eg 2011/12) did have separate sensor and transmitter boards which were individually replaceable, except: (i) this was later superseded by an all-in-one harness for improved reliability; and (ii) it's getting increasingly difficult to source the individual spares for Rev F and before.

All in all for a Vue dating from eg 2009-2012 IMO it's best to replace the complete ISS. The original Vue sensors will have given decent service for eg 8-10 years but will all be wearing and drifting. And the cost of the replacing individual parts, especially the transmitter board, is still not cheap and may require other parts being replaced before too long. Best to bite the bullet and replace the complete ISS.

try changing the channel on the station and console.  my ISS lost wind speed late last year, I changed the channel on the station and the console. that repaired the problem.

I had this problem with a used unit that I purchased.  I purchased a new Wind Speed Cartridge from Scaled Instruments for around $16 plus shipping and installed it myself with no problem.  Fixed the wind issue.

So I would just need this https://www.scaledinstruments.com/shop/davis-instruments/davis-7345-271-vantage-vue-wind-speed-cartridge/ ? What I also need the wind cups or just use the old ones?

[Kamakzie]

Yeah since my unit is from 2009 it might be a good idea to get a new one.

Probably not. But right now you have provided scant information as to the symptoms. If it is actually a 10yo Vue then the most likely cause is a faulty reed switch. A new wind cartridge isn't going to fix that. Is the wind cups spindle still easy to turn or is it stiff or stuck?

It seems to still spin freely but I think it's probably time to retire this one.

You may want consider just a VP2 ISS as your replacement, your Vue console will work fine with it.

A little rich for my blood plus I really could use a new display as well because the battery compartment was corroded by battery acid and no longer functions as a battery backup.

I just noticed today that it seems to be working again. It's a little breezy so I don't know why. I'll probably try to hold out longer as all the other functions work properly. Just a little weird.
