Let’s say you live in Sydney, Australia and there is a garage door opener and want to get an exact time you departed today in one file. The accuracy you need is up to 1 minute and it should be in “YYYY-MM-DD HH:MM:SS” format. Your device uses Datastream with ID 20 and virtual pin 6 for open/close commands. Let’s say you also need to get the list of all the Events that were recorded during this period.
