You definitely have a small yard!  :shock:

It would be in your best interest to keep the rain gauge and temperature units (ISS) in your yard if possible. I am speaking from experience here I don't know how many times a bird has left a calling card in my rain gauge which plugs it up. The bird droppings also eat into the plastic if left for several days. I am on my second rain bucket.  :-(

I've had my VP2+ now for 11 years. Mine is mounted on a 8' 4"x4" with the ISS @ 5' elevation. My Anemometer is at 14' elevation it is mounted to galvanized steel pole which is mounted to the 4x4.

Regards,

I may have to, but I'd really like to avoid having it in the backyard grass area due to it being so small as it is, my gardener having to mow around it, and my horse size dogs making a chew toy out of it.

Plus as you can see in that picture there's a large tree in the South East corner, plus the house to the north, garage to the west, and 6ft fence around the entire property worries me that they may reduce the amount of rain actually recorded.

It may end up being a trial and error process to start with since I have a terrible area for a personal weather station.

In case you're unaware, you'll have three choices on aspiration rates, 1) leave both batteries out for maximum daytime aspiration and zero at night (this is what I used until I went a/c), 2) one battery in, one out, this is for lesser daytime aspiration and some at night, 3) both batteries in for maximum night time aspiration and the least in the day (personally, I wouldn't go this route).

Why wouldn't you go with option 3?

Being that you're in an equally hot climate as myself with wicked solar insolation, I'd want the fan sucking air through that sensor chamber as fast as the ISS will allow with the stock fan. With keeping that chamber as close to ambient as possible, the more accurate it'll be. Of course some say "really, what's a degree", I'll take better accuracy over lesser every single day.

That makes sense.
Now that you've explained I guess my assumptions made me read what you originally wrote wrong. I was assuming that both batteries would make the fan run at maximum speed day and night.

No sir. What happens is that the large solar panel angled out on the bottom not only powers the fan in the day, it also recharges one or both batteries that were used the previous night, at the same time. So, if one or both are in, the current from the panel is not just powering the fan in the day, it's using current to charge the batteries too, taking power from the fan.

Well that makes perfect sense now that I Actually think about it.

As far as the VP2 goes it really doesn't fall into the overly expensive category as if you really want to go into all that stuff re aspirated this and heated that and not on the roof but this has to be on the ground and .... then that stuff is out there and then you may call it expensive and that's even before you get beyond the hobby stage

Wait a minute, you have a "so small" yard, a gardener, and "horse size dogs"?  What is the gardener for...filling in holes?   :-D

Never said the VP2 was expensive, said the hobby is going to be. Since ill probably end up buying more and more weather related stuff. Although the VP2 is "expensive" if you compare it to you typical "home" station.

Mostly for the front yard haha, and yes he actually does fill in the holes from time to time :grin:

Expensive hobby? Hardly.  One and done, for the most part.  If you want expensive, try radio control planes or boats.  :)

One thing about the current production of the VP2s is the newer rain bucket.  I've had the hour-glass shaped one with the bird spikes up for a few months now and haven't had the first problem with it being clogged with bird gifts.  I've been *very* pleased with that design.  So, other than not being optimal for rain collection a higher installation of the ISS may not cause much of a problem with the rain gauge clogging.  Temperature and humidity measurements, along with rain measurements may be affected though.

Put the old bucket back on.  Seriously, that's Davis' answer for heating the new aero-cone setup.....

Based on my experience, I would not bother with a heater.  Just my .02.

Since October 1, 2017 with Heater on 24/7.   Davis rain collector 3.43"  CoCoRaHS  7.57"   Granted, siting is different for the two, but not that bad.

Heater  for  SWE.  A plastic gauge would likely overflow with some of the stores we get here.  Plus it requires manual reading.

I've been down on heaters also... Not just the Davis bucket but Texas Electronics too.  But I've had 2 recent snows where temperatures were just below freezing 28-31° range and the tipping bucket actually matched the manual Cocorahs.
Where they won't match are cold dry storms where lots of evaporation occurs prior to filling tipper. Unfortunately most of our snows upper plains are of that variety where snowfall occurs between -10 and 15°F. The warmer snows recently came in March and have been rare since moving here 4 winters ago... So for some I can see where the heated tipping bucket could work.
