This is a weewx driver for Fine Offset WH23xx hardware. These stations are commonly available as Tycon TP2700, Froggit WH4000, Renkforce WH2315 (Conrad) weather stations.
- install weewx, select 'Simulator' driver (as placeholder)
See http://weewx.com/docs/usersguide.htm#installing
Note that I installed on Raspberry Pi model 3+ (Buster) as follows:
- Add the weewx apt repository key
wget -qO - http://weewx.com/keys.html | sudo apt-key add - - Add the weewx repository
sudo wget -qO - https://weewx.com/apt/weewx-python3.list | sudo tee /etc/apt/sources.list.d/weewx.list - Install weewx
sudo apt install weewx - I also had to default to Python3 and install pymysql as I store the data on a remote MySQL server
sudo apt-get install python3-pymysql
- download the driver
wget -O weewx-wh23xx.zip https://github.com/EdwinGH/weewx-wh23xx/archive/master.zip
- install the driver
sudo wee_extension --install weewx-wh23xx.zip
- configure the driver (now select wh23xx, it should appear in the list of drivers)
sudo wee_config --reconfigure
I had to make some updates to the config file myself, for example remove the port. My wh23xx section of the weewx.conf looks as follows:
[WH23xx]
# This section is for Fine Offset WH23xx stations
# The model name such as Tycon, or TP2700
model = Renkforce WH2315
# The driver to use:
driver = user.wh23xx
- systemd service file
I replaced the LSB init.d file with a proper systemd service file in /etc/systemd/system:
# systemd configuration for weewx
# created by EZ to replace /etc/init.d/weewx (removed this file)

# The following two lines are not in the current distribution version, but should be uncommented and used if you
# have changed the [Service] section to automatically restart the weewx service if it crashes. As noted below,
# this can be particularly useful if weewx has an IP connection to the weather station it is monitoring, since
# transient WiFi network problems are quite common, and may cause weewx to crash.

Then added by:
sudo systemctl enable --now weewx.service
sudo systemctl daemon-reload
- Activating weewx
sudo systemctl start weewx
