Davis Vantage Vue Weather Station

I've wanted a weather station for quite some time.  Things have conspired against me to do it though until I worked through a few issues to make it happen.
My old house sat low in a holler and was surrounded by many large trees making it generally unsuitable to weather monitoring. Leaves and twigs plug everything, so even a rain gauge was sometimes an issue.
The house I live in now is in a very rural area, but open and much higher in elevation.  I didn't really want a weather station if it couldn't be online and my internet choices are somewhat limited.  There is no cable or DSL where I live which limits the availability of an always-on internet connection.  My internet connection for the last couple years has been cellular.  There is a data cap, but the reception is good enough I can get a reliable 4g (HSPA+) connection.  4GLTE is nearby; hopefully it will expand a few hundred yards more some day as the LTE speeds are pretty impressive.  I won't hold my breath.

In order to make cellular work for my overall needs, it has to be reliable and work with a couple devices at the same time.  So, I retired my air card and bought a used AT&T Elevate from an Amazon Partner.  I could have reupped my AT&T service and got one "for free" but used Elevates are readily available for very reasonable prices.

I had to play around with the settings to get an always on connection, but that was pretty easy to figure out.  One benefit to getting a MIFI over the smaller air card was I can put it in a spot in the house where the connection is better, giving even better speeds than I previously had.

With a stable internet connection, I needed a computer to hook my weather station to.  I have an old desktop which works and is reliable, but it is very large and I wanted the weather station to be placed in the kitchen so a large computer wouldn't do.  I poked around and found the Asus EeeBox.  These are remarkably small computers, about the size of two DVD packages stacked on top of each other.  I didn't want to pay full retail but was able to buy one of these from and Ebay Auction for around $60.  That was a steal!  It came in great shape.  While not a supercomputing powerhouse, the demands for a local stable internet connection for a weather station don't require a lot of processing power.
Originally I was looking for a very small monitor to go with it.  The plan was to hide the computer above the kitchen cabinets and then have a small monitor on the wall.  The EeeBox came with a bracket to mount it to a monitor which seemed like a better idea.  I had to drill new mounting holes in the bracket to clear the power cord on a smaller 18" HP monitor, but once that was done the entire computer with wireless keyboard and mouse combo make a perfectly small kitchen computer.  Yeah, the cords are ugly.

OK, big deal, now there is a computer in the kitchen.  I thought this was about a weather station?

I've researched weather station options for quite some time and there are lots to choose from.  I'm actually surprised there were no WIFI weather stations available.  There are options to have a very small (even smaller than the EeeBox) dedicated Linux weather server, but that seemed to limiting.
After looking at all the available weather stations, I chose the Davis Vantage Vue.  This seemed like a very good compromise on price, features and reliability.  Some of the cheaper stations have lots of negative reviews and questionable reliability.  These do sit outside all year round, exposed to heat, freezing weather, rain, etc.  There are definitely more functional units available, but this is a hobby.  I'm not trying to become a meteorologist.  I'm just a local weather nut who would like to be able to monitor weather in my back yard (even if I'm across the country).
Davis had more expensive units that I considered, but I liked the compact sensor "suite" which allowed simple mounting.  If someone is going to purchase a Davis unit, shop around.  Prices are all over the place.  I was able to buy both the Davis Vantage Vue and the WeatherLink software with data logger for nearly the same price as some of the cheaper units available.  I'm confident this was the right choice for me.

The Vantage Vue comes neatly packaged in a box with some assembly required, but it is super easy with very good instructions.  Obviously, the sensors need to be mounted outside.  I had read reviews saying the "tipping bucket" rain gauges can be negatively affected by a wobbly mount so I was paranoid about making sure I had a good solid post to mount the unit on.
After looking at options, what I ended up doing was using one of the corner posts of my chain link fence.  I bought a top rail section of fencing and put it inside the corner post.  In the area between the inner and outer post, I poured a slightly thinned slurry of concrete.  This post is SOLID - almost frighteningly so.

In order to cap the posts and make it less unattractive, I used a whole saw and hand cut the top post cap of the chain link fence and sanded it to precisely fit the top rail post.  I think this makes a very nice look. Once the weather warms, I'll probably put a think bead of silicone to prevent water intrusion and corrosion even thought it is galvanized.

I let the cement harden overnight before assembling and mounting the Vantage Vue ISS.  I'm very happy with the outside mounting of the overall unit!

With the sensors ready to go, I turned back inside to the console and computer.
The Davis console connected instantly with the outside unit.  Davis says it will receive at 1000 feet.  The sensors are only about 65 feet from the house so the connection is great.  Within a short time everything was working and I was monitoring the weather.  The Davis manuals are acceptable, they do a good job of installation, playing around with the features of the console was almost easier by trial and error once I understood the basic flow of the unit.

In order to connect the Vantage Vue Console to a computer, you must buy their WeatherLink software which comes with a data logger.  The data logger can hold months (or more) worth of data and has a USB-out to connect to the computer.  I think the data logger is the purchase, the software just happens to come with it.

The Asus EeeBox does not have an optical drive, so I copied the entire CD on another computer to a USB memory stick.  I installed the Davis WeatherLink software from the memory stick and then plugged the console into the computer (the manual says to do it in this order).  Within a few minutes, I was monitoring the weather on my computer.
I've read a lot of negative reviews of WeatherLink.  After using WeatherLink and a couple other options (as well as looking at a few more), I think I'm sticking with WeatherLink.  I don't think the software is too bad, but the documentation is poor.  Cumulus has some nice features, but I didn't really see any advantage once I played around with those two options.  WeatherLink also has some nice features that I didn't know about until I clicked around a lot and found some hints online.  I will say, I think Davis' hardware is more advanced than their software and associated documentation.
Once the decision was made to use WeatherLink, I wall-mounted the console and tucked everything out of the way.  I still need to do something with the birds nest of cords behind the computer/monitor, but I may get a UPS first (a day after I started posting weather data, we had a power outage).  Even without power, the console has battery back-up (C-batteries, haven't bought those in years) so data is collected.

 After getting the sensor set up and mounted; the console up and talking with the sensor, and the console talking with the computer, it was time to get online.
I registered my station with Weather Underground.  Weather Underground makes a "module" to directly send data from the WeatherLink software to Weather Underground.  The instructions to do this are on Weather Underground's web site and it is very straight forward.  Within a short amount of time I could see my data online.
Then I saw I could also include a weather webcam - yep, I gotta do that too!  I have a window only a few feet from the weather computer.  I had a cheap webcam I had never used that I bought for around $5.  I hooked it up and it connected to the EeeBox quickly.  Weather Underground has instructions for webcams which is also really easy.
There are several options for WebCam software.  I chose YAWCam as it did everything I wanted it to do including saving images locally on a different schedule that what is posted to online, and setting a schedule where the software is not constantly sending black night-time images.
I did find that I had to "reconnect" the webcam to the station several times on Weather Underground's web site before the two seemed tied together permanently.  Within a few hours, I was able to see my weather station history and webcam online.  Too cool!

Unfortunately, a $5 webcam takes two-bit pictures and I was taking weather webcam shots through a window and screen, further deteriorating the images.  The results were less than satisfactory.  Additionally the webcam seemed to set the light exposure when it was plugged in and then never adjusted again resulting in over and under exposure most of the time.

Looking at other weather webcams online, I knew that I could do better even through a screen.  I went to a local very good computer store and perused the options.  On the bottom of the rack was a Microsoft LifeCam HD-5000 that someone had returned, for a very big discount.  It only came with 30-day guarantee.   I figured since it was going to be on almost continuously, if it didn't work, I would know very quickly.
Picture quality isn't perfect, but probably about as good as I can get looking through a window and screen.

It took a few days before my station was seen as an option in Weather Underground.  I can now see my station online and on my Android phone using the Weather Underground website.  There are also other phone apps to see Weather Underground station data.

I also wanted to connect with the Citizens Weather Observation Program or CWOP.  This is a program which takes local weather station data and sends to NOAA for use in very short term models as well as refining local weather patterns.
This was less straight forward than Weather Underground, but instructions to do this from WeatherLink are available online.  The CWOP program started out as a way to send data using HAM radio.  Since its birth was pre-internet, the path from computer to NOAA is hopelessly complicated.  The data also goes through a quality check at some bounce in the process.  I've read many adequate pages on the CWOP and understand the basics, but not much beyond that.  This is an interface between private weather enthusiasts and the federal government.  There is evidence of bureaucracy and understanding the acronyms is not trivial:  CWOP MADIS, WXQA, findu.com, APRS...  I'm just happy the instructions to send data to the system are relatively easy.  I wish there was a single web page that explained the system in total in plain English.  There are some decent Wiki's on the subject but the text still looks like it came out of Dilbert's Jargonator.  The public-private partnership is also plagued with servers no longer in operation and links, images and pages that no longer exist.
At some point in the near future, I'll dive into this more to understand it better. For now, I know my data is going to NOAA and that the visual tools available to see my data from the program are very useful, especially in monitoring quality vs. other local stations.

Davis' info says that to see your weather it just "requires only a permanent Internet connection, a nice place to put your outdoor sensors, and a few hundred dollars burning a hole in your pocket."

This whole adventure costed a bit more than I expected (<$650; AT&T Elevate, computer, monitor, weather station with data logger/software, webcam, mounting hardware, etc. etc.), but at this point, the weather station has been up and running for over a week.  I'm sending data online with webcam pics to the world.
