I want to find a data logger that will display when my relay is on and how long did it stay on. What would be the best way to do this? Google docs sounds promising?? Thank You for the help
Are you already in charge of the relay from an Arduino, or is "my relay" some random relay in an existing system that you want to tap into?

Thank You... Yes I am in charge of actually 3 relays that are being turn on and off at certain times of the day with an esp8266 12e. I want to record the operation of those relays. I thought a data logger would work. Google docs seem to be the answer but have no experience with data loggers. What is the best way to record data from a Arduino without using sd cards. Thank You for your help
The ESP8266 SPIFFS file system provides capabilities much the same as an SD card.
This guide explains both NTP (internet time) and SPIFFS (buildin flash storage).
