The use of the ESP8266 in the world of IoT

#30528 All the examples of cloud datalogging I have seen so far use a momentary value (e.g. temperature). I would like something else: a value accumulated over a day, in this case mileage of my bike, but it could be power consumption, etc. For example, if I have logged 20 km in one session on a particular day, I would like the value to pick up from 20 on that same day if the logger loses connection or is restarted suddenly. Are there any (free, preferably) cloud IOT services that allow for that?

An alternate solution might be, I suppose, ESP logging in to the service, obtaining last data and starting up from here, but that would complicate things a bit, I guess...
