It looks like
weewx.com does not accept HTTPS web connections. I am not sure who to direct the question to, but would it be possible to move to a new hosting provider that accepts secure connections? If cost is an issue,
Netlfy offers a free
Open Source tier for qualifying projects. The addition of HTTPS on
weewx.com would not only provide the obvious benefit of secure connections, but it would also help improve the overall search ranking for the site. I have taken a preliminary look over the code, and it looks like it would be possible to move the site to Netlify with minimal effort.
