Hi Rajib,
The naming of the two parameters can actually be a bit confusing. Here is the difference:
- Event Time = Date & time of sending/transmission of the respective measured value (reading) or data packet
- Device Time = Date & time of recording the respective measured value (reading), also corresponds to the value “Timestamp” in the “Packages” tab
And yes, both are part of the device payload.
I hope this answers both of your questions.
Best regards!
