WS-2000 Temperature Spike!!! Help!!!
« on: July 29, 2021, 05:40:08 AM »
Yesterday I glanced at the display and the temperature said 102 F! 
Two days earlier I made 2 changes (yea I know at the same time  #-o)
I updated the stations FW to v4.2.9 and I replaced the batteries (lithium, 1st time using lithium)

I went to the weather station and changed the batteries (by that time it displayed 109 F!) and then the temperature was correct or at least in line with other nearby stations.

The temperature started creeping back up so I changed the batteries back to alkaline.

This morning it's showing 77.9 but other station are displaying 71-73......suggestions?  System is 2 years old and it's always been about the same as others until now.

Please Help!

Seems around 2 years these packup in some way or another. Maybe temp sensor on the blink, may need a new one?

Thanks for the reply!

I was hoping there was a part I could change!  Is there only one part that could be causing this?  Is there a temperature sensor and a controller?

Wonder where I find these parts?

Thanks for any help!!!

Can You Roll-Back Firmware? WS-2000
« Reply #4 on: July 29, 2021, 10:04:45 AM »
The other day, I updated the firmware and replaced batteries. 

NOW my WS-2000 is reporting temperatures that are more than 5* higher

Suggestions? 

How can I push an old FW to the Weather Station?


Thanks all!

It is highly unusual , and I've never heard of an instance where a firmware upgrade on a WS-2000 would cause that.

Not saying there isn't some possibility that it occurred, but I think most of would be urging you to look into other factors. I guess the first thing would be to ask what are you comparing it against?

And when you say temperatures (plural) , do you mean indoor and outdoor, or just multiple reads from one or the other?
Also, are the other readings somewhat expected values? Humidity, Wind, etc.

As far as going back to a previous firmware, assuming this is the console firmware, I have never done it, I believe it can be done if you have a previous one. I'd rather not be definitive on that as I have not done it.

Also, if you are not already aware, there are 2 firm wares that can be installed  on these and should be updated as they come out. What I referred to as the console firmware is the one that is loaded by the sd card. The other , is the one that is loaded from the AWnet or WSView apps. These are different and do not replace each other and usually do not come out at the same time as they address different areas of the system. Both should be maintained. Rolling back from the one from WSView or AWnet apps, would be be troublesome as these are provided from the applications, and I don't believe there is a readily  available way to downgrade.

I know, I was not a lot of help here.

So when you say "reporting" do you mean on the console screen or at Ambientweather.net?

So when you say "reporting" do you mean on the console screen or at Ambientweather.net?
To be clear here:
a WS-2000 station consists of three parts:
- the outdoor sensor array [WH65] (which has batteries, but only as backup, usually runs on solar energy)
- the indoor temp/hum/pressure sensor [WH32B](which has batteries)
- the WS-2000 console which doesn't have any batteries
so,
- exchanging batteries at the outdoor array would usually not have any effect on sensor readings
- exchanging batteries on the indoor 3-in-1 sensor could (rarely) have some effect on the sensor readings
- even though the sensors (7-in-1 array, 3-in-1 indoor sensor combo) may but need not to have their own firmware, this is not updated
- the only firmware which is updated is the WiFi firmware for the external weather network communication and the internal console firmware for the console display and sensor processing - WiFi update goes via WSView/awnet app, console via microSD card

Now, what exactly is out of the usual ? the values shown on the console display ? the values posted to a weather network e.g. WU, Ambient ... ? Both ?
Having this information could be helpful for a better assessment of your situation.

In principle, the console can run properly and the weather network posting can be wrong (due to old WiFi firmware). Both the console and weather network data for the same sensors can be wrong due to old WiFi firmware and old console firmware.

In principle you should be able to download the older console firmware from Ambient, put it on a microSD card and start the update process (which would be a downgrade when you provide a user.bin or factory.bin file of an older console firmware version).

If your observed issue is caused by the firmware or not is not forcing - it could be coincidental.

apart from the possibilities of exchanging the temp/hydro module or the whole array ...
it's good to use clear terms:
- station = console + sensors (for a WH2902 or a WS-2000 an outdoor array, for a WS-2000 an extra indoor temp/hum/pressure sensor)

usually changing the batteries of the outdoor array (the console has no batteries) has no effect on the sensor readings as the batteries are for backup only and the array runs on solar energy stored in a super-capacitor

the difference of 4°F / 2°C is not very big, and depending on how far your reference station(s) are away, this could be easily a possible difference for the different locations. As long as near-by doesn't mean a few 100 yards, I wouldn't take that as an indication for a wrongly reading sensor. Are you sure that you have exactly the same micro-climate as your "near-by" stations ?

@Rover1822; @kheller2;  @Gyvate
Thanks for the replies!

Sorry I guess I left out some pertinent information....the elevated temperature was on my console Not on WU or another site

This WS-2000 had been so accurate (compared to other local stations). 

There are "calibration" options and I changed the temp by several degrees but I'll have to watch and see if it tracks like nearby stations until I get a replacement thermometer.

I just want to figure out What cause the spike....it was 82 degrees and the station reported 106

Anyone know if you can purchase a temp sensor?  Is there a controller?  Linky???

Thanks to all!

Unfortunately Ambient have discontinued selling the WH32, a separate outdoor temp/humid sensor.

You could get a sensor replacement for the outdoor array as already posted by @platokidd in your 2nd thread regarding your temperature issue

Is it possible that a firmware update reset a previous calibration? Some firmware updates have wiped out user settings. Sux, but you'll just have to deal with it. Don't like it? Then don't be an early firmware adopter. So I think all you have to do is recalibrate. If recalibration doesn't solve he issue and you continue to have spikes then that to me seems like a sensor that needs replacing and the firmware update was coincidence as there are no other reports. I also recommend getting a second console to see how the sensor is reported. I recommend getting a GW1100 as it is economical and useful.

Regarding rolling back firmware possibility....yes it is possible to roll back both the Revision firmware (via SD card), and you can also revert the WiFi firmware via a specialized app that is not available to the public. You can ask though, but you'll probably not get it. But I don't think this is the solution for the issue at hand.

but... the question still remains, did you see the 106 at WU and Ambient for YOUR station?  or did you see 82 for your station at WU and just your display was showing 106?

Thanks again to all!

After changing the calibration settings for the temperature it seems to be tracking near-by stations (reading station data from console).  I've ordered another Red Spirit Thermometer, will check it's calibration and then check against the station.

I did find the replacement part (guess I was just to lazy to go through all parts since search didn't give me immediate results :-) ).
