Don't think it is possible (tried to search other threads), but any ideas for auto updates to Twitter? Do I just need other software? Any free ones? Or php code possible?
Thanks.
WeatherLink doesn't offer a lot of options for customization. Best bet is to maybe give another software package a try if you want to customize a lot. Otherwise it is going to require a custom script to parse data uploaded with an HTX file and feed it to twitter.
Since you are probably thinking of using twitter like a mobile app on a phone, another option is on-demand rather than a scheduled tweet. Using Anole's wxgraphic script, I frequently check the weather from my old 3G motorola razr dumb-phone. I don't know if there is a phone out there today (with MMS) that this wouldn't work on.
