Does anybody have work on any Personal Weather Ststion? Looking to display the data.

I did look on before. all what I found was related to get the data from online weather service. What I am looking is for a PWS installed in my house and get the information local in my Observatory PC.

I found couple but the are using HA with some nodes no available in Nore Red, ex. eqwittmttq server.

Looking now into WeeWX to see how I can implement on Node Red. I am a 72 Year new on node red

I recently shared one of my projects that might perform **some** of the tasks you are looking for.

> [@Single Sensor Node (ESP32-S2-Mini or RPi Pico-W)](https://discourse.nodered.org/t/single-sensor-node-esp32-s2-mini-or-rpi-pico-w/84951):
>
> The project is based on an ESP32-S2-Mini and can be deployed to sense temperature, humidity and air pressure in any geographical location. All it needs is access to a WiFi Access Point and a (local or remote) MQTT broker. Today I've been converting the Micro-Python script I wrote for the ESP32-S2-Mini to work on a RPi Pico-W. One of my friends wanted to try it out but only had a Pico-W. I've called it 'Single Sensor Node' as it sits in my greenhouse and reports Temp/Humidity/Pressure and the …

I've written an 'Installation Guide' (there's a link on the website) that explains all about the project.  
If you would like to read about it, I've published it on my 'Share my projects' website here...

[https://teamwork-int.com/share\_my\_projects/](https://teamwork-int.com/share_my_projects/)  
If you visit the above link you'll need to click on the folder labelled... **C\_single\_sensor\_node**

**SSN\_generic\_RDS\_v05.py** is the latest version of the Python script - works with ESP32-S2 and Pico-W

The project uses a BME280 sensor to measure **temperature/humidity/air pressure** and send the readings via a MQTT broker to Node-RED where the data can be processed. In my particular situation the device is located in a greenhouse at the bottom of my garden. It uses an ESP32-S2-Mini flashed with Micro-Python. Depending on what you want to do, you can use a local or remote MQTT broker.

I have an Oregon weather station that transmits at 433MHz and I use rtl\_433 plus receiver to send data to Node-RED. There are quite a few of this type of weather station on the market. Includes rain gauge, wind sensor and temperature sensors

Thanks for giving us more information.

Do you already have a personal weather station? If so what make and model is it? What sensors does it have?  
This might be relevant in how you get the data into Node-red.

I think WeeWX is software to obtain the weather data? I'm not familiar with it, but Node-red is perfectly capable of accepting data from external python code.

> [@telescopio](#):

I am sure that Home Assistant is very fine software but you can certainly achieve what you want with "just" Node-red. Most people on this forum don't use Home Assistant.  
Note that it's easy to add features to Node-red, there is a whole library of such add-ons at [flows.nodered.org](http://flows.nodered.org).  
It's very common to use MQTT because it can make communicating between Node-red and other devices very much easier. You might end up using it.

So the first stage is getting weather observations into Node-red. Once you can do that, you can start designing your weather display.

Thanks for your time. I have one Ecowitt GW 1000 server with sensor GS68 Anenometer. Let me tell you that I have the Agg Solo weather from Lunatico that is using UDP to comunicate with a private driver.

I had bad experience with this brand, first I lost a DragonFly unit to control the OBSY, relays failures I did replace it with a PLC Modbus.Now the Anenometer fail so I decide to look for other unit more reliable.

[https://lunaticoastro.com/node-red-tutorial-for-dragonfly-and-cloudwatcher-solo](https://lunaticoastro.com/node-red-tutorial-for-dragonfly-and-cloudwatcher-solo)/

This link show the flow that I am using with the agg solo weather that I did some changes.

Maybe this will help those who want to help me. THANKS FOR YOUR TIME

Can you share your Node Red flow so I can wotk on it? I will love takenanlook andnsee if I can adopt some ideas.

You will have to change the device ID's to match yours but this is a cutdown version of my flows. The final debug nodes are actually Dashboard chart nodes. The MQTT in is from a Pi running rtl\_433 (using a USB receiver to get the info from the actual devices)
