Hi, I have addedd a “waterproof” type DS18B20 temperature to my raspberry pi project, and its early days, but seems to work with Cayenne very well. What I can’t find out is, when I ask Cayenne to download the historical data to my hard drive, my PC can’t regognise the file format and hence, I can’t open it. Anybody know the secret of reading the temperature data gathered in this way. And how long does it go back in time does it collect the data from requesting it ?
a day before
a week before
a month ???
Thanks
