AcuRite Weather Stations / Re: Access Connection Issues

Signal strength of sensors reported by my Access are constantly jumping between 1-4. But they always stay connected and it gets the data. I donít know how the Access works, but I wonder if thereís a firmware problem with the Access when reporting signal strength and how its measured. Different sensors send data at different intervals, maybe itís just getting confused and needs a longer interval to look for signals. I donít know what ďSignal StrengthĒ means on the Access, but maybe its just bad firmware and not hardware.

My displays always show constant signal strength, itís only the Access where the signal strength fluctuates so much.

The receiver chip in the Access (and SmartHUB) computes an RSSI value each time a transmission is received.  It ranges from 1 to 4 based on how well it was "heard".

The displays show "signal strength" a different way because they don't have a receiver that generates an RSSI value.  Instead, they start with full bars, then subtract bars periodically as expected data packets are missed.  That means you can't really compare the signal strength on the Access with the "signal strength" on the displays.  Their behavior just isn't the same.

It's unlikely to be bad firmware.  47 has been out for quite a while now, and most of the "connection" complaints have gone away.  They seemed to have solved it on the server side, which indicates the bulk of the problems probably weren't local RF reception issues, but a problem somewhere in the back-end servers, probably in the specific API for the Access.

So if you're still having problems, I'd guess there's an issue in your particular Access hardware, assuming it's not a local noise problem.

We originally bought property in Cloudcroft (up above Alamogordo in the mountains) and then a couple years later found the property we finally built on here in Datil.

We would fly in to El Paso (from Seattle) and I always liked the humor of the message "Eat Pecans" that a farmer had spelled out in 200' letters with Pecan shells under the flight path, in Las Cruces.

The VLA is about 20 miles (as the crow flies) from our house, to the east.

I have run in to instances of people thinking we are located in Mexico a couple times.
I usually just say "We are the state between Texas and Arizona".  :-)

Awesome setup and gorgeous view you have there, Greg.

Thank you.
They do call it "The Land of Enchantment" and I find that people either love it or hate it.
We love it.

We have visited NM numerous times over the years. I subscribe to New Mexico magazine and I always get a kick out of the "One of our 50 is missing" page.

We visited the VLA (has it already been almost 19 years?), but have spent more time in the Las Cruces and Alamogordo areas. I really love the White Sands National Monument.

While looking at weather related stuff on ebay, I saw a display and electronics box for AWS that I'd seen in the remote past.

It looks a lot like a Texas Weather Intruments display, with solar and a few other LED sections added, housed in a light oak colored frame, and in this case (different from other display-only ebay listings I've seen some years ago) had an electronics box associated with it.  No sensor package seemed to have survived this one's life.

I was curious as to the history of this device.  Was it a private company?  I recall that it may have been part of a project to have installed and monitored by students in schools.  With the modem connector it seems to be pre-internet, and designed to talk back to some central location to report, but how often and was that information available for viewing by other participants?

How widespread was it at the culmination?  How many years did the project last?  Did the organizers go under and these stations suddenly become boat anchors?  Was it a Texas Weather hardware device, and what did the external sensors look like and were they very accurate?

I'm curious as to whether any of the members of this forum were participants and have any comments from real experience?

Broke our previous wind speed record the other day with a new wind speed record of 81 mph.

http://www.datilcam.com/weather/thismonth.htm

I was curious about how wind speeds are figured so I looked around on the net and found this.....

On the Beaufort wind scale......

But please remember that the Beaufort scale was originally developed only for use at sea, where wind speeds tend to be more sustained and less gusty in nature. The way that this is applied nowadays is that the Beaufort scale should only be used in relation to mean wind speeds (10-minute mean is the preferred measure I think, but 2-min may substitute).

So it's really not correct to talk about eg a Force 7 gust because gust speeds simply don't relate to Beaufort, you need to be checking the maximum mean/average speeds.

On the Beaufort wind scale......
Near-gale force winds are 28 to 33 knots. (32.22 to 37.97 mph)
Gale force winds are 34 to 40 knots  (39.13 to 46.03 mph)
Strong gale force winds are 40 to 47 knots. (46.03 to 54.09 mph)
Winds above 47 knots and below 64 knots are storm winds. (54.09 to 73.65 mph)
Sixty-four knots and above are hurricane force winds. A wind, not necessarily a hurricane, having a speed of more than 72 miles per hour (32 m/sec): the strongest of the winds.

Rivers almost made it to flood stage a week or so ago, then fell off about 10-15 feet.  Now back on the rise and expected to reach the same near flood stage levels by next week.

It takes a (word I can't use here) of water to cause a wide river to rise 10-15 feet over several square miles of land.

Air Quality Sensors / PurpleAir PA-II and RF noise
« Last post by torkelmj on Today at 07:28:32 AM »
A word of warning regarding the PA-II for those hams / amateur radio operators intending to install one:

The PA-II (or the included power supply, I didn't dig further into the issue) generates a huge amount of RF radio noise.
I operate it of the 230 VAC mains @ 50 Hz and the PA-II renders large portions of the HF radio spectrum useless. The PA-II isn't located anywhere near the antenna or transmission line systems.

Once outdoor temperatures get a bit more friendly I'll try changing the power supply for another one to see if it helps.

Map shows strong temperature change from cold front passing through central Oklahoma on Tuesday afternoon.  For now there is a winter weather advisory for the possibility of light icing. 

It's coming my way, too.  Brrr.
