Title: OS WMR300
Post by: Weather Display on May 31, 2013, 06:20:56 PM
Hi
I have a sample here of this new 'High precission professional station'
First impressions are very impressive
its huge
its like a Davis VP
The rain gauge is like identicle to the Davis VP
Will update once I have it all setup :)

I didn't realize there was one in the works.  I guess they were tired of getting there butts kicked by Davis.

I found this picture.  Is this the right one?

yup, thats the one...upside down wind and all
see:
http://sandaysoft.com/forum/viewtopic.php?f=5&t=9939

a Davis employee has posted that its a copycat

The data protocol to the PC has changed (the HID device has changed...I have changed that to be able to open..but no data is arriving..so I need to find out what they have changed), compared to the WMR200 anyway

It appears data logging and PC interface (w/software) are included with the system so it isn't a complete Davis copy. Flipping the wind sensor around would be my first modification if I had that. Wind cups and bird feet don't mix. ;)

Think maybe that was an attempt to avoid a Davis lawsuit?

there is no software included with the sample I have
I was hoping it would work like the WMR200 for software so that its compatible
but they must have changed the data protocol a bit..I will try and find out more

There's a YouTube video of the assembly https://www.youtube.com/watch?v=4_tNJ2LEjXM. The inside and out looks like Davis. Interesting the video uploader has disabled comments. Gee I wonder why?

It will be interesting, I have zero faith that somehow OS could jump from the 200 to something functional much less a Davis competitor. The devil will be in the transmission technology, something OS hasn't exactly mastered in the past.

That was one of several thoughts I had about it.  I wonder if they'll require a datalogger or just some software like the 968 (that would be a plus).

And their sensor accuracy and reliability needs a lot of improvement.

But they're way behind Davis in product interchangeability.  They have such a large line of repeaters, accessories, consoles, remote transmitters, etc.

And if OS doesn't improve their customer service, then gold-plated stations won't improve their reputation.

Of course, the outcome remains to be seen.  Stay tuned................
Title: Re: OS WMR300
Post by: Weather Display on June 01, 2013, 03:05:51 PM
it has a built in data logger
like the WMR200

the windspeed on the console updates every 2.5 seconds...which is great

the radiation sheild for the temp/hum sensor is great...best I have seen yet from OS
(the rain gauge and radiation shield are the same size as the Davis station, as is the windspeed/direction)
There is a plug socket for UV and solar...which is still to be available...and there is mount holes for those on the rain gauge...just like a Davis

(its like that add...sounds like a Golf, looks like a Golf!)

its a very positive move by OS, they have done a great job from what I can see so far...as long as they can avoid any legal copyright or similar


one problem I am having is that I have been testing the pairing of the base station to the transmitter...after 1 hour it says in the manual to reset a DIP switch on the transmitter (SW4)
but I cant get a re pair sync to work again (have reset console and transmitter)
(am doing this because the rain was dashed out on the console)


Title: Re: OS WMR300
Post by: stevebrtx on June 01, 2013, 03:51:54 PM
Have reset the console and the transmitter and still nada? - I'd say you just made my case. And, if the DL is even remotely like the 200 run, don't walk, away.

Many years ago I sold microfilm, Rochester Film was cheap junk, they were bought out and the product dramatically improved, but the horse was far out of the barn by then and they could have made perfect film and no one would buy it at any price, they failed not long after as I recall.
Title: Re: OS WMR300
Post by: Weather Display on June 01, 2013, 04:06:06 PM
WD does not have too many problems with the WMR200 data logger
(most of the problems are actually with the supplied usb dll file and how that works)


but yeah, I am struggling to get the console to resync/pair up again, after the 1 hour period after first time
(I.e I have powered down/reset the console to test to be able to re sync up again)
looking for a master override to reset the flash memory on the console (and not a bigger hammer), LOL
Title: Re: OS WMR300
Post by: Weather Display on June 01, 2013, 05:02:52 PM
ok, good news, I got it to sync up again
I had to remove the previously paired up channel (default is channel  8 )..I saw that in the manual how to do that but did not realise that is needed to reset a previously synced up pair that you wanted to re sync up
then reset the transmitter then vola
rain is showing now too on the console and working too (fast response too , like 2 second after tipping the bucket)
impressed
hopefully this thread will help someone in the future with syncing up problems
:)

I took a look at the manual last night. What I find interesting, The SIM does contain solar and UV connectors for sensors. The manual also says they're coming out with a leaf/soil station like the Davis 6345. However looking at the console screen shot of start up there doesn't look to be anything on the console for UV solar leaf wetness or soil moisture. And these options aren't mentioned anywhere else in the manual. I'm just curious as to where this data would be displayed?

After a little "diggin" I came across this website which shows system accuracy & specifications (which look GOOD):

http://corporate.oregonscientific.com/template/wmr300/WMR300_proWeatherStation.html (http://corporate.oregonscientific.com/template/wmr300/WMR300_proWeatherStation.html)

New TX frequency, 915MHz(USA), with supposedly greater TX distance (300m).
Outdoor sensor update interval: 2.5-20 seconds.
Outside (12 sec.) and inside (1 min.) RH accuracy 3% from 0%-to-99% RH.

Capable of handling up to 8 additional T/RH wireless sensors, but those sensors are NOT yet available.

Wireless reception working great here (I have mounted it outside now)

The console LCD numbers font could be a little bit clearer though (they are bit 'chunky' maybe?)

Post by: Skywatch on June 02, 2013, 10:31:15 PM
After taking another look at the manual it appears the station like other Oregon Scientific stations report wind speed in decimal numbers instead of whole numbers. How is the sensitivity of the anemometer and wind vane? Does it report at 0.1 mph or is it like the WMR200 that starts at 0.9?

I also noticed the solar panel is smaller. I'm curious as to how well it produces power?
Title: Re: OS WMR300
Post by: Weather Display on June 03, 2013, 12:07:40 AM
cup sensitivity is really good for low windspeed
and the 2.5 second updates is really good too
humidity-> dew point is tracking similar as my Davis VP (mine is reading a bit high), and the same as my nearst Metar and another station

solar panel is not small
Title: Re: OS WMR300
Post by: Skywatch on June 03, 2013, 12:37:16 AM
According to the web site for the WMR300 still uses just barometric pressure for the forecast. I wonder how this rates against the VP2's more sophisticated algorithm?

Title: Re: OS WMR300
Post by: Skywatch on June 03, 2013, 10:55:38 PM
Brian. I think the term "flipping" is used metaphorically to explain how the Davis anemometer might be better built or designed if the cups were on top. Personally I like the anemometers that use the cross arms like the Heath Kit wind sensors.
Title: Re: OS WMR300
Post by: Weather Display on June 03, 2013, 11:37:26 PM
had heavy rain here today
and the rain gauge has performed well :)

I have also tried out the beta software being developed for it now
flashy/bright and modern looking
(but is not getting any data though at this stage..at least for me )
Title: Re: OS WMR300
Post by: FrozenPenguin on June 04, 2013, 05:14:52 AM

Looks pretty good.   Would consider, but my WMR200 is still running great (now via my raspberry PI).   As for the visual resemblence to the vp station...who cares.  Hopefully VP isn't Apple, and suing everything that may look like a consolidated weather station (rounded corners!)


Title: Re: OS WMR300
Post by: mcrossley on June 04, 2013, 05:53:27 AM
It will be interesting to see if the sensors are interchangeable with VP2. For the diagrams and videos I have seen, the TH sensor looks like the same module, and the wind speed may be a direct clone of the Davis mouldings like the rain buckets (Brian?), and wind direction seems to be using the same potentiometer technology as Davis so I wouldn't be surprised if it used same resistance.
Title: Re: OS WMR300
Post by: Weather Display on June 04, 2013, 05:59:54 AM
The rain bucket and assembly is a direct clone
the windspeed/direction and mount are not 100% the same
(for starters its "upside down")
but would probably work with a davis station, assuming the calibration was the same

currently showing 98% on the WMR300 and 100% on my Davis (which it has been on all day due to lots of rain (winter time here))

yes, the temp/hum sensor looks to be the same as the davis

99% humidity now on the console....windows are all fogged up in the house...so yup its high humidity
when we get a fog, will know if it gets to 100% OK

so far looking great though

impressed

99% 100% still sounds good enough.

I wonder if the UV and solar sensors will look like Davis's.

When will Oregon Scientific release this for sale?

Yes, it was the lousey accuracy of the WMR200 %RH outdoor sensor(s) that drove me to abandon OSI and move UP to Davis VP2.

I got the provided (I had to download it) software working now
I had to flash the firmware,as the OS had not been loaded yet

I am able to get data arriving into a test program now, but need to decode it (OS are not going to release the data protocol until August)
Also its looking like the station will be available in the shops in a month or 2
Title: Re: OS WMR300

Title: Re: OS WMR300
Post by: Weather Display on June 06, 2013, 11:55:04 PM
I forgot to mention that the barometer on the console is to 1 decimal place for hpa (unlike the WMR200)
but not on the software that comes with it
I have managed to get data flowing in a test program and have managed to decode all the data except for barometer
(waiting on that to change so I can find it in the data)
The data will most likely have barometer to 1 decimal place I presume
So I will be able to add support to WD for this station
(not history data yet at this stage, just live data)

the software that comes with it does produce a log file, but its in binary format, i.e not readable (a .dat file)
Title: Re: OS WMR300
Post by: Weather Display on June 07, 2013, 05:28:39 AM
also the windspeed is real sensitive, measures like 1.3mph

i.e faster than a Davis VP
I am impressed with this station :)

Post by: Old Tele man on June 07, 2013, 02:22:04 PM
Although NOT a good idea for actual use, but what is the fastest sustained update and transmit rate (assuming USB) that it's capable of? How close to actual "realtime" is it capable of?

according to manual (which is online)
its 915mhz, 816mhz for the EU version (WMR300A?)
1000 ft range or so
wind is transmitted every 2.5 seconds
Title: Re: OS WMR300
Post by: Tornado Tim on June 08, 2013, 07:07:59 PM
Even the radio frequencies are very similar to the VP2.

It looks like a plain copy with a few alterations. Davis could actually have a go at them in court if they lodged patents on the design.
Title: Re: OS WMR300
Post by: Weather Display on June 08, 2013, 08:44:52 PM
I have figured out the history data now
a big improvement over the WMR200 is the fact you can set to keep the history data on the console (with the WMR200 its sent only once)

also its now available in Europe to purchase...cost there is a bit more than a Davis VP..but when you figure it has the built in data logger, similar price

What am I missing about this sensor suite?

1. You want the anemometer either 10' or 30' AGL.

2. The temperature s/b measured about 5 feet AGL.

3. The rain bucket should be much closer to the ground -- like 12 to 24 inches AGL.

At least that's what the official standards are saying. It's great to have excellent accuracy on the measurements, but if you cannot locate the various sensors in the proper place, then accurate readings are of dubious value.

I've always been puzzled by the Davis multi-sensor suite in this regards.

Is it possible to separate these units from each other and locate them at correct heights? I've never looked at the Davis manual to see if that's possible ... can the OS sensor suite be separated like that?

It's possible but the short cable lengths between the rain gauge and thermo/hygro is prohibitive of this kind of installation unless one obtains an extension cable. Another flaw of the Davis ISS design is wind flow. The rain gauge needs to be sheltered from wind to get accurate rainfall measurements. While the radiation shield (passive non-fan aspirated) requires about 5 mph of wind to keep the air inside the sensor housing "fresh". Otherwise stale air can result in inaccurate temperature and humidity measurements. I think in the VP2 ISS Davis went for simplicity. Which many people like. But this is with the cost of accuracy. Those hidden flaws.  ;)

Regarding OEM...I found this blog post:

http://sandaysoft.com/forum/viewtopic.php?f=5&t=9939 (http://sandaysoft.com/forum/viewtopic.php?f=5&t=9939)

where someone named "susanf" is purporting to be associated with Davis and denies that there is any association. Based on this I have no idea what is going on now...such a blatant copy seems surprising but who knows?

Here's another confuser: OS says they have NIST certification ... but most of their stuff is manufactured in China ... but Davis manufactures in the US which makes NIST certification more logical. Are the WMR300 sensors manufactured in the US? Can you get NIST certification for a product manufactured in China?

I wonder if the sensors use frequency-hopping and if so, do they use the same hop sequence as Davis (which has already been published on the internet)?

Sorry, many more questions than answers!

Post by: Weather Display on June 15, 2013, 12:03:35 AM
the way the console and transmitter work is different to Davis from what I can gather
(with the WMR300 you pair them up,on 1 of 8 channels to select from )
Note that lots of remote stations that are not Davis use the Davis rain gauge
another thing, the rain gauge is not black like the Davis, but is dark gray instead (same for windspeed/direction)
The transmitter housing and solar panel are also bigger on the WMR300
Title: Re: OS WMR300
Post by: Weather Display on July 03, 2013, 06:35:32 PM

That's in agreement with Cabela's estimated ship date being 5-6 weeks from now.  
http://www.cabelas.com/product/Oregon-Scientific-Ultra-Pro-Weather-Station-WMR/1608261.uts
It will be telling whether that estimated shipping date stays stuck at 5-6 weeks out, or if it counts down as the weeks pass.

Is $650 the price people were expecting?  That seems like quite a jump up from the wmr200 pricing.  I'm not saying there isn't value to justify the price, but it does largely divorce the wmr300 from probably the bulk of OS's prior customer base, who probably would have already bought a Davis if they were prepared to spend $650.

Any guesses as to how expensive the temp&RH sensors might be?  i.e. What's everybody's best guess as to the likely price on the 915Mhz equivalent to the THGR810?  I'm guessing the price will be higher, because it sounds as though it will be utilizing a more accurate, digital sensor.  So, if the street price on a THGR810 is about $40-$50, I'm guessing the street price on the 915Mhz unit, with a more accurate sensor and triple the RF range, will be $60-$80?

From what I've read on this forum here, the design is frozen?  i.e. they're not still doing major debugging?   So, manufacturing is the only bottleneck?  OS should want to provide their sales channel with inventory before the 4Q shopping frenzy.

I like that they've tripled the range over the wmr200 (so, allegedly, 1000 foot range, just like the Davis), and also that it can wirelessly monitor up to 10 sensors without requiring them to be clustered.  i.e. you can position them individually however and wherever you see fit.  It's that flexibility, plus maybe some near-term leapfrog over Davis in accuracy and/or update speeds, that will attract buyers.  Or, did  miss something?  If not, then for buyers who don't value those two attributes, or who value it less than Davis's proven track record in the field (together with being the sort of de facto "safe" choice that still nets IBM a lot of business), it may be a tough sell.  Unless there's more to the value proposition than we've heard, I'm surprised OS didn't price it more aggressively, at least in the near-term, to get a more rapid market penetration and gain faster acceptance among a larger number of the opinion leaders.

How do you guys see it?

In one aspect, the WMR300 seems to be a logical "up-grade/migration" from the earlier WMR200, ie: both have 10 sensor capability...something none of the Davis systems have.

FWIW, the additional WMR200 T/H sensors were (A) cheap, costing less than $50 each (GOOD), but also (B) had rather lousy %RH specs (BAD). Hopefully, this is corrected in the "new" WMR300 sensors?!?!

there has been a couple of revisions to the software that OS provides and to the console firmware over the last 2 months

Is there weather software that can fuse the data from two different weather stations (say, one operating 433mhz and one operating a 915Mhz)?  If so, which weather software can do that the best and most easily?

Benefits would be:
1.  It would facilitate an upgrade path for the users who want to milk their existing system for all it is worth, but who can replace worn-out sensors and gauges with improved devices as their old devices get retired.  
2.  It would allow you to monitor up to 20 devices, without being limited to 10.
3.  It would allow the use of cheap, inexpensive sensors in those situations where they would still be "good enough".  
4.  The cheaper, more range limited sensors could be positioned closer to the base receiver, and the higher cost, longer range devices could go further out.
5.  Possibly separate the two receivers but network their data back to the PC that's running the software, thereby providing yet another, different way to expand RF coverage.

I see that they went on temperature from -55 on the WMR 200 to -40 f on the 300. So that is an step backwards in my opinion. Guess They don' t think about cold climates. Hit -64 here last wanted.

I wonder if they fixed the "humidity does change below minus 10C" bug.

its the same temp/hum sensor that Davis uses pretty much
So I would say so

yes you can separate them

I believe it can be separated by using the extension cable, see this copied from OS FAQ

Q2.   Can I connect the bundled wind, rain or temperature & humidity (thermo/hygro) sensor separately?

A.   As wind, rain and temperature & humidity (thermo/hygro) sensors require transmitter box for data transmission, they cannot be used separately. However, you can place the Anemometer/ wind direction sensor away from the transmitter box with the 12m cable of the sensor. Also, separate transmitter & mounting parts for additional temperature & humidity (thermo/hygro) sensors will be available later.

Personally, I think this is a backward step and one thing I dislike about my Davis Vue. I also have an OS 100 and 200, which is far more flexible when choosing a site location. Agreed, it is a far more substantial station than any previous station offered by OS, but the fact that the two censors can only be separated by using a cable is a none starter for me.

The fact they it can be separated at all (with or without cables) is a big plus in my book. I would imagine that if the Vue or other "all-in-one" stations had the 'separable with cable" option that some folks would use that option with their stations. I know I would. ;)

Yup, it's much easier to "cut & splice" wire than it is to "chop & saw" plastic when performing DIY sensor separations...of course, 'wireless' would've been even better (wink,wink)!

the WMR300 is like the Davis VP
you can separate out the sensors (rain/temp/wind) (via increasing the length of the cables etc)
no backward steps in reality

Now Cabelas says expected to ship in 4-5 weeks (instead of 5-6 weeks about a week ago).  So, that's at least some, admittedly meager, evidence in favor of it being a real ship date rather than just optimistic advertising.
http://www.cabelas.com/product/Oregon-Scientific-Ultra-Pro-Weather-Station-WMR/1608261.uts

Has anyone seen the WMR300 posted for sale (or pre-orders) on any other websites yet?  Any links?

At $650 US. Seems to be in stock, at least as far as I was able to go on the web site w/o actually entering a credit card.

Any word when the available sensors(UV/Solar) are going to be made available to the public?

I've never owned an OS system, but a couple of quick observations...

The new system sure better be darn good for an asking price of $650!

Second, as seen in the attached photo, why is a company based in the U.S. showing METRIC readings on its console for its publicity shoot? I was like  :evil:

These may be minor points / observations to some, but to me these kinds of things make or break a deal. Sorry.
