Capture your data with a simple device like a Raspberry Pi and post the measurements to your hosting provider so you can display your data in real-time on your own website. It is also possible to run PWdashboard from the local device using the original Weewx database. As all graph creation and calculations are done on the fly on the client, the load on the local device is kept to a minimum.
The dashboard is cross-browser & cross-platform compatible. You can easily customize graphs by editing the index.htm file.
