Fine Offset WH2900 sensors failing - anything to be done?
« on: May 22, 2024, 03:53:06 AM »
Hello there! My Fine Offset WH2900 has been outside and running since April 2021. It has worked fine but now the sensors are starting to fail. I get no reading for barometric pressure, outside air temperature, UW index/solar radiation. Is there something that can be done, f. ex. replacing the circuit board, or do I have to buy a new unit?

barometric pressure is measured in the console => it cannot be (only) the outdoor array.
It rather points to the console.
Did you try a console factory reset (before you do it, note down your calibration values, rain totals etc. as they will get lost during factory reset).
If this doesn't help - and a reset of your outdoor array neither (see WiKi http://meshka.eu/Ecowitt/dokuwiki/doku.php?id=start#sensor_array_doesn_t_seem_to_provide_data), your console may be defective.

Maybe changing the backup batteries of the console will help (a WH2910 console should have backup batteries which have to be taken out for the factory reset --> manual).

For a final confirmation - as you are way out of warranty - I would get myself a GW1200 gateway (30 USD, good investment, one of the most modern and capable displayless consoles --> WiKi - can always be used as a backup or for extension of the station with more sensors) and check if you can receive the outdoor array and its sensor readings.
If yes, your console is defective - you may have a look at the new WS3800/WS39x0 consoles which can also receive your outdoor array (and all other modern existing Ecowitt sensors  --> WiKi for console topic and reviews)

your barmetric pressure is there in the custom server string - if it is not shown on the console display, the display may be defective. I'd send your results - console not showing on display (picture) and the custom server string, to support@ecowitt.com.

They may offer (or you can ask for) a replacement display (WH2910) which you would then have to replace yourself (open the housing, replace display (probably a few screws and one flat cable)).

A new WH2910 console is around 69 USD, but if you need to get you a new one, I'd suggest to pay a few $$$/ more (79 USD) and get your self the WS3900 console instead - opposite to the WH2810 conole the WS3900 can receive and process many more sensors including IoT sensors (of course only if you can to get more sensors) - beyond that the WS3900 is in my opinion the better choice.
You can read the description and review in the WiKi (see my signatue)

Ive reset both console and the WH65A transmitter. Seems to me that the sensors in the transmitter are failing rather than the console. Wind and rain measuring is working, the rest not.  :sad: I will take the transmitter apart during the summer and see what the circuits look like but it is beyond me to repair IC tech.

when the custom server string shows barometric pressure and your console doesn't (and the sensor for the barometric pressure is on the console PCB !!), what makes you think that your console is OK and the outdoor array which does never post barometric pressure is faulty ???
With such symptoms I conclude that the console display is defective - and doing whatever work on the outdoor array will not make the pressure appear on the console display.

In another thread it was stated that, at least on the ws80, the T/H sensor can die in such a way to take out the bus and thus affect the solar/uv readings.  I'm curious if the Y wing has a similar issue.
Granted, none of that should have anything to do with barometer readings.    (And I hate to mention this, but I thought I read somewhere that the display might not show other sensors if its not receiving T? from the outdoor array but instead would show ---)

even though I was sure I knew, I just made a test - taking my WS2320 console (same display setup like the WH2910 - difference: format and colour). Took the console and drove with it 500 m away to be out of range of the outdoor array. - and still saw all values  :roll: - then took the batteries off and re-inserted - it showed "----" for everything except the indoor T/H and the pressure; but then suddenly everything appeared again - looks like the transmission even works over 500 m  =D>
Took it to another place 800 m away - and had full reception - and a different transmitter ID ... ](*,)
picked up the WS69 from some other station. Finally drove to the forest - an now only indoor T/RH plus pressure.

So, when the console doesn' show pressure, its display (or it's pressure sensor or both are defective).
If it shows only wind when connected to the console but no pressure, the WS69/WH65 T/RH sensor could also be defective but need not.

If the OP has another Ecowitt station with a WH65 nearby, he could take his console close (100 m) to that array and see what the console shows. The WH2910 like the WS2320 have battery backup.

The console display shows (except for time, date, moon phase...) Pressure (rel/hpa), indoor temp/hum, wind, rain.
Not displayed (i.e. - - . -) outdoor temp/hum, UVI, Light.
In my initial post I wrote I got no reading for barometric pressure, that was wrong. The unit is 30 minutes drive away from home at an airfield.

then it's likely to be the T/RH sensor of the outdoor array* - depending on its age (hardware revision), you can get yourself a replacement sensor (see https://meshka.eu/Ecowitt/dokuwiki/doku.php?id=start#ws69_wh65), available at shop.ecowitt.com
I assume it's the older one - in the picture item #4 called Temp & Hygr. (~ 8 USD).

Just open the radiation shield and see if the sensor is pluggable - if yes and the plug is blue, get yourself https://shop.ecowitt.com/collections/accessories-for-ws80/products/sht35-temp-hygr - if black, https://shop.ecowitt.com/collections/accessories-for-ws80/products/sht35-temp-hygr-1 (never mind the shop saying is WS80 accessory - it is but it's the same sensor for the WS69). If not pluggable, go for the first suggestion above (Temp & Hygr) for WS69.

*) when it fails, it also makes the solar readings fail

I enjoyed this story. I felt i was right here with you on that trip.  :-P

Thanks for all replies so far, very helpful. I also get daily reports that battery is low, although I replaced them last week. Is it the capacitor that is failing also?

when you can be sure that your batteries were not only replaced but also still good, this could be.
But I would first see that the T/RH sensor gets replaced - the battery low information may be distorted due to the defective T/RH sensor. Even with batteries only, but new, fresh ones, they should hold longer than one week. The WS69 doesn't use that much energy.
I would first replace the T/RH sensor, reset the array (warm - and cold if necessary --> WiKi) and then see what it gives.
