Outdoor temperature no longer reporting HP3501UB
« on: June 01, 2023, 02:08:59 PM »
Station was running fine. Now outdoor temperature and related are no longer reporting for about a month now. It was working fine. Situation unchanged after firmware upate today and installing new batteries.

Any idea how to get my outdoor temperature back?

I have the following:
HP3501BU
Wh32B (pressure is reporting from this unit - which is why the outdoor temp not showing up seems unusual ... when it was working before)
WH31B (denoted at Channel 2)
rain sensor
wind sensor

Here are some screenshots

the sensors you have mentioned are either indoor sensors (WH32B) or extra temp sensors (WH31).
You didn't tell us, what's the sensor you are supposed to get the outdoor temp/hum readings from.
Is it the WH65 7-in-1 outdoor array ? (from which you also get the wind and rain data)
Or is your "B" the frequency sign B (B = 915 MHz) ?
Your location in the U.S. would make this likely.
It's obviously not an Ambient model as the HP350x consoles/stations are not sold by AMbient; they are Ecowitt only afaik.
But just to be clear:
The WH32B is obviously the 3-in-1 indoor sensor (new Ecowitt name: WH32 indoor) as it provides the pressure (plus indoor T/H).

Let me assume that you have a WH65/WS69 (Y or I shape) outdoor array.
When it doesn't post any outdoor T/H data anymore, then either the sensor cable between the sensor sitting inside the radiation shield under the rain gauge and the array mainboard has become loose [1] (vibrations of the pole caused by winds) or the sensor is defective [2]. Or the electronics has got stuck somehow and needs a reset [3].

[3] a: soft reset - put a staple end into the reset hole on the underside of the array (exact position see manual) for more than 5 seconds
b: (if a doesn't yield the desired result) hard reset - remove the batteries from the array, cover the solar panel tightly with black tape and wait until the LED sitting on the underside stops blinking (can take up to 72 hours) - the re-insert the batteries
if [3] doesn't help, go for [1]
open the radiation shield (2 screws) and check the cable going from the sensor to the mainboard for sitting tightly in its socket
if [1] doesn't help either, you can get yourself a T/H outdoor sensor (or the whole rain bucket-T/H sensor kit) from shop.ecowitt.com (accessories for WS69).
If your array are still on  warranty, ask your supplier for replacement of either the sensor or the rain bucket/radiation shield with T/H sensor kit.

TLDR: Can not find outdoor sensor and battery finally died causing the issue of the outdoor temp/related not showing up. Thanks for the info that helped me deduce the problem/solution.
---------
Thanks for the reply and sorry for not giving the
 - rain (WH40) and
 - wind sensors (WS68).

The WH32B is the name of the sensor - printed on the front of the sensor. I thought the indoor temperature was coming from the display unit ... mystery solved. The temperature on the WH32B is showing up at the indoor temperature. ... now for the Outdoor temperature mystery

I thought the outside was coming from the WH32B. Now I know that is not the case.

I really do not know where the outdoor temperature was coming from. I do know it was correct.

... (some research was done)

Turns out I bought a total of 3 sensors. I can not find one. I think the battery finally ran out ... and thus mystery solved. Sorry to have wasted  your time but there was information gleamed through this process that was very helpful.

in your now described scenario the WH32(B) - B like 915 MHz - is the outdoor T/H sensor* - and the T/H/P is provided by the console.
You may have to change the batteries of the WH32 (outdoor) sensor - and actively connect it again to your console (Setup inside the console, sensor ID page - the WH32 outdoor is named there T&H).
Then it should also show the same values which it shows on the sensor display on the console display.
If you have your WH32 outdoor sensor indoors, it will of course show the inside temperature on its display.  ;)
Still, by definition, the WH32 outdoor sensor will show as outdoor sensor on the console display.
Afaik the HP350x consoles have their indoor T/H and pressure sensor inbuilt.

*) the WH32 outdoor sensor has usually printed temperature/humidity under the little display, whereas the WH32 B (B like barometer) indoor sensor has temperature, humidity, pressure printed on it. The WH32B indoor sensor is only used by the HP25x0 , the HP350x and the WH2650/WH2682 consoles.

No, the HP350x also uses the WH32B (aka WH32 indoor).

OK - then there are two WH32 in the game - a WH32 outdoor and a WH32B indoor. To be distinguished by the print under their display: outdoor temperature, humidity; indoor: temperature, humidity, pressure
inside the console setup (page sensors ID) the WH32 outdoor goes by "T&H" and the WH32B indoor goes by "T&HP"

I've had a similar issue with the outdoor unit of my WH2950 (Ambient) station. The outdoor temperature and humidity are flat-lining at -40C and 10% RH. Everything else working fine.

I'm having trouble dentifying/confirming a source for obtaining a replacement for the sensor, which has "WHP01" marked on it.
The closest I've seen is a Misol  part on Aliexpress which looks compatible physically (except for the short connection lead, but I can handle that).

How can I find out if this Misol part would be a compatible replacement?

Alternatively, what sensor chip is used? Would it be an SHT30 ? (I can't read the marking on the faulty sensor unfortunately)

TIA

Thanks, yes it looks physically like the part needed, but not sure what IC is buried in the sealant and whether it would be compatible with  my 2950. The model numbers mentioned are sort of similar but not identical.
Also, The ribbon cable isn’t the same, and I don’t have a socket to plug it in to, but can manually splice it onto existing wiring to reach the circuit board.
Can I assume it would work being from roughly the same family (WS2000?)

For the WH2950 , I'm not familiar with an Ambient system that has that model . The other vendors that have a WH2950 use the older style "boat"  array., which looks like the WS1000 from Ambient.

Can you post a pic of the outdoor array?

  WS-2000

Maybe I'm not reporting the manufacturer correctly, probably a clone, just have 'WH2950' displayed on the back of the console.
The humidity temperature sensor had a clothy surround that has disintegrated over time. So I've tried to expose the part number of the sensor assembly and so far have 'WHP01 2017/??' on the PCB. (Can't make out the lettering on the I2C chip, would it be 'SHT30' or similar??

Think I may have found a source for replacing the Temperature/Humidity outdoor sensor for my WH2950 PanTech Weather Station on the ecowitt site.

Goto https://shop.ecowitt.com/products/temp-hygr  (Accessories for WS69). It even includes instructions for how to fit the sensor to older style sensor arrays that dont have the connectorised version sensor!

What you have is known as WH24 array, not the WS69.

The older version they are talking about is the older version of the WS69.

I have no idea if the part is compatible.

  WS-2000

There are two different versions depending on the age of the WH24. 

This thread and the ones it links to might help. It looks like you have the digital version, not analog.

Thanks for all the help everyone. I've now managed to get a full part number off the sensor using a microscope after cutting the sensor out of the sealant.
We have an SHT30!
Now will wait for replacement order to arrive.

Thanks again.

Have now received the replacement sensor ordered at shop.ecowitt.com.
Cut the plug off and soldered the 4 leads as shown.
Pin 1 (red stripe) of ribbon cable on new sensor (also an SHT30 I was told by the supplier) = SDA
Pin 2= GND, Pin3 =VCC, Pin 4 = SCL.
Now back up and working!

Photo of final connections.

If you feel the sensor through the gauze to orientate it the same way as the old sensor, then the pinouts on the ribbon cable will be as denoted on the old sensor PCB.

Good job. Many of those have gone bad. It is good to see a path for the unit to still be viable in its original form.
