>From researching cheetah generator it looks like most of the python syntax carries over when outputting complex expressions using #echo. So I have tried a few python options, primarily variants of datetime or time.localtime() - timedelta(1) but they're not defined. I am not sure where I can import a module that will not be overwritten in upgrades. I tried adding the import to /usr/share/weewx/user/extensions.py but it doesn't seem to carry over. I have seen a few examples using time-86400, but I would have to define time in epoch values somewhere as well.
I've learned more python than when I first installed WeeWX, and I'm trying to bridge the gaps, but I'm just not there. Cheetah throws another kink in... and the user guide is less thorough than I would have hoped. Thank you in advance to any more suggestions on how to specify yesterday's date in the link either in skin.conf or index.html.tmpl! -Jonathan † On Sunday, September 16, 2018 at 2:30:20 PM UTC-5, Jonathan Zitelman wrote: > > Thanks!
