4pro RX keeps silent, no comm with CMX anymore.

Sat, 25 Jul 2026 12:08:31 +0100

Dear all,
i had a working setup with a 4proRX that receives one TX with 2 T/H sensors (1 Rain- and 1 FakeWind-Sensor (4,7kOhm inserted)) and one AQMIII configured as Indoor Airlink Sensor. The RX communicated with a CumulusMX on a RPI via tttyUSB0. this test-setup was running for nearly 2 month now. but i ran in serious problems.

what happend?
i uploaded the latest sketch (v6.3_b008) for the RX via arduino (IDE 1.8.19) and boardmanager 2.0.14 ESP32.
my guess is, that accidently i had "Erase all flash before sketch upload" activated. but i don´t really know it.
after the upload the spiffs was empty, fonts and pictures were gone. letters on the display were very little.
everything else seemed to function, sensors were received, and data were displayed correctly. but the communication with cumulusMX was gone.
the latest error section of cumulusMX shows a long list of "WakeVP: *** VP2 Not woken"

next try: connected the 4proRX directly to the LinuxMint notebook with arduino IDE and did a fresh sketch-upload with "Erase flash" before. After successful upload, i transferred the complete "data" folder to SPIFFS via ESP32 Sketch Data Upload Tool

i checked everything. is the correct USB connection in use (yes it is /dev/ttyUSB0 connected to cp210x)
when i reboot the rpi - restart cumulusMX, whats the output of Log:

2026-07-25 11:29:52 - You are not running the latest version of Cumulus MX, Version 5.1.5 - Build 5012 is available.

My next guess was, that i changed something in config.h, but i can´t find a bug. Pls find the config.h attached below. I did further investigation with direct usb connection and debug mode to see the comm. in Serial.Monitor of the IDE. I even did a debug-session with directly connected RX to the Notebook and Serial Monitor. If there´s interest, i´ll post the outcome here too.

Conclusio until now
So while sensor readings are displayed on the WD pro4RX, it seems to me, that the communication with cumulusMX in Davis Mode is completly gone. cumulusMX dashboard keeps empty with 0° and zero time. But there´s one interesting part: the AQMIII readings are displayed in CMX -> Extra Sensors -> Airlink Sensors.

Thanks in advance, and greetings from Austria.

Problem with Optional CO2 sensor

Tue, 10 Feb 2026 17:04:30 +0000

Hi.
After a long time and a lot of reading I managed to get the AQM-III working.
But the only problem I have is with the Sensirion SCD30, it worked for 2 reboots then stopped and shows me 0.
I have Arduino IDE 1.8.19 / ESP32 2.0.3 and firmware 6.1_b013.
I would appreciate any help. Is there a chance that the Sensor is broken?

George.

Config Flow (UI setup) – just enter IP/hostname
Automatic sensor creation
Clean naming (no WeatherDuino
prefixes in Home Assistant)
Uses the device-reported ID for proper device naming
Supported sensors (depending on your 4Pro configuration):
- Temperature & humidity (indoor / outdoor)
- Barometric pressure
- Wind (speed, gust, direction)
- Rain (rate & total today)
- Solar radiation / UV index
- Air quality (CO₂, PM2.5, PM10, AQI)
- Soil moisture sensors
- Additional external sensors (ES1–ES4)

📊 Dashboard Examples Included

Windrose Card (24h / 4h wind distribution)

Load error and system reboot issue

Fri, 09 Jan 2026 04:19:12 +0000

I am getting the following error when the AQ111 initially loads.

E (4070) gpio: gpio_set_level(226): GPIO output gpio_num error

Also, the AQ111 reboots the cpu every second refresh of the PMS7003, refer towards the end of the output from the serial port I have attached. Would appear that the reset is triggered by the load error.

Am using Arduino 1.8.19 and libraries supplied.

Any assistance would be appreciated.

i use it Arduino IDE 1.8.19
Sorry but I have no knowledge at all about IDE .
Any help is welcome .

Firmware Update instructions in case you forgot

Wed, 05 Nov 2025 01:54:57 +0000

I had some trouble to remember how to do the firmware update so I made a small howto for those who tend to forget things and don't work often with Arduino IDE. The instructions below should save you some time and are similar to what I published on the CumulusMX forum (in the Alpha thread).

--------------

If you still have the Arduino IDE (1.8.19) config it is easy: just download the new firmware from the site (look at the date), unzip into the Arduino directory and compile and upload to the board.

If you don't have the config:

Install the IDE 1.8.19
Install the ESP32 board:
- In your Arduino IDE, go to File> Preferences.
- Open the Boards Manager. Go to Tools > Board > Boards Manager…
- Search for ESP32 and press install button for the “ESP32 by Espressif Systems“
- Install version 2.0.3
Move the WeatherDuino_AQM_III directory from the zip to the Arduino directory. It contains a libraries, software and utilities directory
Move the libraries directory from the firmware zip up to the Arduino directory first level
Edit the Config_Options.h and Credentials.h to what you need
Verify and when no errors => Upload

I think that should be it.
Don't even try other versions of the IDE and Board unless you want to experiment.
If werk_ag decides to move to a next IDE version no doubt he will indicate which versions you need and publish the libraries accordingly.

Compile errors

Fri, 31 Oct 2025 12:04:23 +0000

Hi,
I downloaded your firmware for the AQMIII to start work on my current AQMIII to get it fixed for the problem I reported earlier.
I finally managed to get the correct board in place (ESP32 Dev Module) and compiled the code as is after configuration.
I get loads of errors, the short version - all library resolve seems to go OK - is below. I can post the long version as well.

Any suggestion? (IDE version 2.3.6; and no this is not my daily doing so you may be verbose)
Should I update the libs, if so howto without damage?

Code:

AirLink response

Thu, 30 Oct 2025 11:58:12 +0000

Hi,

I am running CumulusMX with an AQMIII sensor in an Alpha test setup for version CMX 4.7 (with .NET10 and VS2026). This development setup did not read/register data from my AQMIII (dated 2021 I think). Mcrossley wrote:

"OK, your AirLink issue is tracked down. The now stricter JSON parsing is throwing an error because the JSON being returned does not comply with the Davis specification.

It is the final field "error".

My real AirLink returns ...."error":null
yours returns.... "error":0

The Davis spec says

Quote:The error field is usually null on success, but in the event of an error, will be an object with two fields - code and message.
code is a numeric error code
message is a human readable error message string describing the error.

So error should normally be null or...

Code:
"error":{"code":123,"message":"Error message"}

"

Could you change the firmware to reflect this please?

You can contact Mark on the CMX forum if need be.

Hello, I'm surely doing something very obviously wrong, but I cannot get the software to compile, I get an error that the libraries are missing. I've updated the location of the files in the IDE preferences (I'm using 1.8.19 on mac Sonoma) to the provided libraries:

Apologies for the very basic question and thanks in advance for any help,

Hi Forks.
I couldn't find a Stevenson screen that looked like a real one, so I had a crack at designing on in Fusion. I'm still a novice designer but thought it turn out really well, especiallt the print in place door. Any feed back appreciated.

Looking for Advice on a Reliable Personal Weather Station

Tue, 29 Jul 2025 19:27:49 +0100

Hi everyone,
I'm planning to set up a personal weather station at home to track temperature, humidity, pressure, and wind. I'd appreciate any advice on what equipment to choose.
Here’s what I’m looking for:

Budget: around €200–€500
Accurate sensors, especially for temperature and humidity
Easy setup with Weather Underground or MeteoCercal
Low maintenance (solar or long battery life)
Good outdoor durability

As someone who works in custom plastic fabrication, I’m also curious if anyone here has ever designed or modified enclosures or sensor housings to handle harsh weather better. I’d love to hear how you’ve customized your setup.
Thanks in advance for the tips!
