Run raspbian-lite, add what you need, turn everything off you don't. You might want to run a lower-powered pi as well. Weewx runs fine on a pi-zero or zero-w if you wanted to go that way, depending on whether you want wired or wireless. I don't know about 3g personally. I'm not sure what you mean about 'some other crap' but you certainly could tweak the skin configs to not generate images or html pages if you work a little. Really comes down to how minimal you want to make it. If you're not generating any output other than saving data to the database, how are you going to access what weewx is receiving from the station ? Are you planning to rsync something pi=>somewhere periodically ? -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
