I just wanted to read the power data from my lawn mower and exported the data as so called csv. This is how the content looks like: "deviceId","name","timestamp","value" 196,"Rasenmaeher",1523595578,6.225 First of all, this so called CSV data can not be imported in excel directly, it must be pre-processed first to lead to a reasonable result. my main question is about the timestamp. what format is this? 1523595578 how to translate this into a date and time? anyone
