As a studied atmospheric scientist it is almost a duty to operate a personal weather station (PWS).
Here you can see the outside sensors.
Below is a picture of the basis station.
It is a Renkfore WH2315 radio weather station. The station has a radio connection to a basis station and this is connected to a Raspberry Pi. I used Rasperry Pi OS (32-bit, released 2021-10-30). Via the open source software WeeWX the data is than hosted on Weather Underground.
Below you can see a my setting (arrows define the connections).
Here you can see a sample screenshot of my PWS taken from Weather Underground suitable to the photos above.
Installation of WeeWX and hosting via Weather Underground:
I followed basically the WeeWX debian documentation.
pi@raspberrypi:~ $
wget -qO - https://weewx.com/apt/weewx-python3.list | sudo tee /etc/apt/sources.list.d/weewx.list
sudo apt-get update
sudo apt-get install weewx
Because the driver for the Renkforce WH2315 station is not available in WeeWX it has to be installed seperatly see https://github.com/EdwinGH/weewx-wh23xx/). I used than later WH23xx as the driver.
Status of the weather station:
pi@raspberrypi:~ $
sudo tail -f /var/log/syslog
or
