You can have the Pi summarize your data for the day and send it to you using an Adafruit
FONA 3G Cellular Breakout - American version - FREE Ting Sim Card w/ Purchase! TING has a 3G SIM card for the FONA, I have one that I am using. If you decide to go with this setup, once you receive the TING card call them and upgrade it to a 3G, no cost difference. 2G service is limited and being eliminated from most cell sites. All the cell sites around me no longer have 2G service. My cellular TING bill is $7.26/month.
So, have the Pi summary sent to you at 9PM like I do. You can even have alerts sent to you, door sensors, temperature sensor, battery voltage (current voltage, or if the battery is being stolen).
Here is what I am working on, but using the Arduino to capture the data from the sensors. You will need a source to keep your batteries topped off.
