Add a feature to enable “Timestamp” on Terminals in the App.
So evertime the device is printing a new row, the terminal adds automatically the timestamp (hh.mm.ss).
Same like the Arduino Serial Monitor
All development on the current version of Blynk ended around 2 years ago.
The new version is due to begin closed beta testing soon. I’d suggest that you wait and see what features that brings.
In the meantime, it’s a simple matter to add this in your code, using the RTC widget to obtain the current time and prefixing the time to your terminal print commands.
