A hack that I use that is only production quality for me
Subscribes to an MQTT feed from WeeWX and pulls out the temperature. The temperature is then set, along with the camera name, as left text in a Motion webcam display.
Supports multiple cameras via the config file
The config file /etc/motioneye/mqtt.txt should consist of
space-seperated lines of text, with the first element being the name
of the camera (this could be any arbitrary string) and the second
being the Motion Web Control URL for that camera. An example is
included in the examples directory.
An example systemd unit file is included in the examples directory. To us it:
sudo cp motion-weewx-mqtt.py /usr/local/bin/
sudo cp examples/motion-weewx.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable motion-weewx
sudo systemctl start motion-weewx
This should have the script running as a daemon that starts at boot on Linux systems that use systemd. If your system doesn't use systemd or if you're not using Linux, then you are likely advanced enough to install this on your system.
