It is relatively easy to integrate LiV with IFTTT.
I tested IFTTT a couple of month ago for posting tweets (that was right before I added twitter functionality to LiV Pi code base)
What I did was: I created a recipe that has a trigger (temp_alert) that runs on LiV Pi and an action (post on Twitter). Please refer to second screen capture (look at first tweet, ignore the rest - that was just testing for the LiV software release V1_0 that added twitter support).
To add triggers on LiV Pi:
Create a recipe on IFTTT with "YOUR_TRIGGER" on Maker channel and action on whatever channel you want (google drive channel in your case)
Add trigger code to LiV Pi.
You could do something like this:
In your programming language of choice, on your development machine (this could be LiV Pi or another computer), write a loop and use LiV JSON REST API to read most recent
measurements with "http://IP_ADDRESS_OF_LIV/getAllRawSensorData" (returns JSON).
