I have been using weewx for several months running on a headless Raspberry Pi 4 connected to my old David Weather Monitor II. It's been working perfectly with great reliability. In fact it has breathed new life into my 25 year old WMII.

Recently I connected a 7" HDMI monitor to the (headless) Pi 4 hoping to use it to display weather data to supplement the old WMII console. The Pi sees the display and shows a login screen but I do not know how use the display for output while logged into the Pi via VNC.

Any suggestions?

Thanks,

Dave R.

The simple way to do this is have the Pi start up in desktop mode, auto login, and launch a web browser pointed to your weewx web site (which can just be the local html directory).

For the first part, run rasps-config and set the boot options to Desktop/CLI->Desktop Autologin. To get the browser launched, see for example https://raspberrypi.stackexchange.com/questions/69204/open-chromium-full-screen-on-start-up where the website is something like /var/www/weewx/index.html depending on your weewx installation.

I'd suggest a raspberry pi forum, as your question doesn't seem to be weewx-related.

Some forums on Reddit that have tens of thousands of subscribers would include:
